Triple sockets: overview, connection features, types and diagrams. How to install an internal triple socket Are there triple sockets

Installing a triple socket can be a solution for those who do not plan to make repairs in their apartment in the near future, but want to comfortably use the electrician in every room of their apartment. To turn one outlet into three, you have three options. Let's consider each of them.

Installing a block of three outlets

Block of three outlets looks great on the wall

The most acceptable way in terms of price / quality ratio. It is desirable to carry out installation at the stage of repair / plastering, but installation on a finished wall is also possible. More details about

Advantages of the method:

You can make not 3, but 4 or even 5 sockets in one block, depending on the brand and model of the electrical device;
Reliability and ease of installation;
Low cost

Flaws:

The work is dusty - you have to drill sockets
Requires a special tool (perforator, crowns)

Connectors and sockets in one block

Mounting a block of several outlets is the most common modern solution. In fact, you get several separate sockets in one place, moreover, you can use socket boxes to mount not only sockets, but also switches, Ethernet and TV connectors.

Installation of a triple built-in socket mechanism

Often it is not possible to install a block of three sockets, because. not enough space. The considered option with the installation of a block of three sockets, depending on the company and brand, will take from 240 to 260 mm. But this length can be significantly reduced if multi-gang sockets are used with factory installation in one block. Together with the overlay frame, it will take no more than 160 mm

High-quality automatic terminals in the factory module for several sockets

Advantages of this approach:

Easier socket installation
No need to connect anything with additional wires
Takes up less space
Factory installation of electricians is more reliable than any manual

Flaws:

A factory-made block of three sockets costs more than three sockets from the same manufacturer purchased separately. For example, if the Legrand mechanism for three sockets costs $3*4=$12, then the triple multi-gang socket mechanism will cost you $26, that is, twice as much.
Requires a special socket for three modules

Important: When buying, make sure that the purchased module is securely attached to a special socket. It is better to use modules and sockets from the same manufacturer.

Triple socket - economy option

Triple earthed socket

No electrician in their right mind would advise you to install such triple sockets permanently. They can normally serve as a carry-extension, but no more. Nevertheless, on the market you can often find products of Kuntsevo Electro and similar companies that offer you 3 sockets at once for a price of less than $ 4.

Advantages of this solution:

They take up less space than the options described above - three sockets are placed in a 95 * 95cm block;
Price. The mechanism of a normal Legrand socket costs $ 4, and here, together with the case for three pieces, the same price.

And here are the disadvantages:

Due to its design, the socket cannot normally be attached to one standard socket and will constantly fall out of it. No matter how carefully you use it, it will definitely fall out!
The quality of the plastic used. Self-respecting firms do not produce sockets of this format, and all the rest, including Kuntsevo Electro, use cheap combustible plastic, so the use of such sockets even as temporary houses is very dangerous.
Contacts. Inside these sockets there is no copper, no bronze, no brass. Only painted tin. This is how it's done cheap goods. After watching a video about the production of sockets in Kuntsevo and even disassembling such a socket, you will see supposedly brass in contact groups, however, everything immediately falls into place if you check this "brass" with a magnet. After some time, tin contacts cease to spring, they transmit electricity through the plug worse, heat up, and rust. In general, they do everything that tin should do in circumstances unusual for it.

Do not install such sockets without special need for yourself or the customer. In both cases, it will cost you more.

Comments:

Determination of the installation location

Where to put the socket block? Comfort, aesthetics, and safety are all taken into account. But it is necessary to take into account the safety rules and technical operation. If you look at European standards, then the distance between the floor and such a block should be 20-40 cm, according to Soviet - 100-120 cm . Perhaps the location will depend on the installation method.. And she happens:

outdoor;
internal.

Outdoor is used in old buildings, in industrial, non-residential premises. Produced directly on the wall. The cable or wires are placed in a tray made of non-combustible material.

In new houses and in premises after renovation, as a rule, internal or hidden wiring is installed, as well as sockets with switches. In any case, wires from junction box to the outlet must be laid strictly vertically or horizontally. This must be taken into account when choosing a place, so that later you do not have to go around obstacles.

Preparatory work

We are talking about installing a triple socket internal. Again, there are two installation methods:

with one socket;
with three sockets.

Whatever the choice, it is necessary to mark the installation site. Some recommend using a level, however, if the floor is not level, the design will look uneven. Therefore, it is better to make the socket for the outlet a little larger so that you can adjust it. If you decide to install a triple socket in one socket, then you need to measure the dimensions of the socket, make a tolerance and gouge a hole in the wall.

When installing three single sockets, you need to put a socket under each of them. Here special precision is needed. It is necessary not only to set the level, but also to calculate the distances so that each of them enters its socket on the front panel.

It is necessary to fasten the socket box firmly, even a little laxity can destroy the plaster, and it will be unpleasant for yourself. You can fix it with dowels, if you have the skill, as you can destroy the socket. However, it will be more practical to use screws, who knows, you may have to change or remove them.

The stores sell kits: screws and sleeves. We put the socket box in the hollowed out socket and mark the place for the fasteners. We drill a hole along the diameter of the sleeve (it can be a little less, but not more) and insert the sleeve, it should hold firmly. When tightening the screw, the sleeve will press even more tightly against the wall. If the wall is brick, you can use an ordinary drill, although if there is a soldered one, the desired diameter is better. For concrete, it’s definitely worth taking a soldered drill, since they are now freely sold.

Wire preparation

It's time to think about laying cables or wires. To do this, you need to decide what you will use. According to the rules, each outlet must have its own wire. If the sockets are provided with grounding, then one more conductor is additionally needed. The earth wire is used without insulation.

It would be nice to have one or two cores in stock. When connecting a triple socket, one of the cores can be damaged. aluminum wire, especially if it is cut, it breaks easily. You can make a mistake and cut shorter than necessary. During work, due to heavy load wires may burn. That's when the backup core will be more than ever useful.

A little more about the material of the conductive conductor. Earlier it was said about the need to think under what load the outlet will work. This is true for wire as well. There are many reference books, tables for calculating the cross section of a conductor, depending on the current passing through it. A stranded conductor carries much more current than a single-core conductor of the same cross section. Based on this, you can decide what will be used - wire or cable.

After you have bought everything you need, draw a line on the wall from the main electrical outlet or box to the nest you made.

Remember, the line must go strictly vertically or horizontally. Hollow out the track so that the cable or wires go completely under the plaster. If there is a suspicion that there will be wiring nearby, it is necessary to de-energize the apartment.

This is possible when the gasket is made to the box, which is nearby, but slightly to the side.

Before installing the socket box, a hole for the wire (cable) is drilled in the case. If there are three of them, then in each of them. After that we fix it to the wall. After securing one end, check the level. If one outlet is crooked, it is hardly noticeable, but if it is triple, it immediately catches the eye. Screw the sockets and go to the wire.

Before you fix the cable, ring all its cores and mark them. In some cables, the insulation of each core is colored in its own color. If wires are used, marking is not needed, but it is necessary to ring. After that, lay them in the groove and secure. Measure the end that will be connected to the network so that it is enough to put it into the box and connect it. Do not forget about the rule - always leave a reserve, even if more is better than not enough. Do not connect to the network yet.

Insert the other end into the socket and connect to the socket terminals. Check the integrity of the wires and the correct connection. This can be done in the following way. A jumper is made from a bare wire and inserted into a socket, then this circuit is called. The same is done with the second and third. Grounding is connected separately, if it is not there, you will have to do it yourself.

It remains to plaster the wires and the socket. If the holes for the wires are very large, they must be sealed so that the plaster does not get inside. After the plaster has dried, seal the wall and cover the triple outlet. It remains to figure out how to connect a triple outlet to the network. Connection can be of two types:

to an existing box, for example, we change a single outlet to a triple one;
directly to the center line.

Connection in a box

First of all, completely de-energize the apartment. Never try to work under voltage! Open the box and inspect the connections. If they are wrapped with electrical tape - unwind, put on caps - remove. This is done in order to provide access to conductive elements. At the same time, try on if the wires fit in the box?

Check the bare wires in the box to make sure they are not touching and apply voltage. Next, it will be necessary to determine where the phase is located - the conductor through which the current comes. You can use an indicator or a device that measures voltage. Everything is clear with the indicator: touch the conductive element, if a light signal appears - this is a phase.

The device is another matter. As it is measured alternating current, it is impossible to understand where the phase is, and where is zero. Therefore, the person himself is used as zero. The probe of the device is taken in one hand, and the other touches all connections in turn. There is no need to be afraid: the current passing through the circuit will be so small that the most sensitive person will not feel it. But for this, the connected scale of the measured voltage on the device must be at least 250 volts.

If there are more than two connection points in the box, you must make sure that the found phase connection refers to the center line.

Connect the phase to the three stripped wires that go to the contacts of the three outlets. The other three, connected to other socket contacts, connect to zero - this is another wire of the central line.

Line connection

To connect to the central line, purchase a junction box in advance. De-energize the apartment, cut the wire of the central line, install the box, strip the wires of the central line and from the outlet, put it all into the box. Connect the wires from the first contacts of the socket to one conductor of the line, connect the wires of the other contacts of the socket to another conductor. Connect the earth to the earth conductor.

Connecting a triple outlet for non-professionals can cause some confusion. But there is nothing complicated in this, and, following our simple tips, you can connect everything in just a few minutes.

The main thing here is attentiveness and not neglecting the safety rules.

Before proceeding directly to the connection, you should decide on the possibility and correctness of our decision. For this , rated current circuit breaker, which feeds this group, as well as the absence of prohibitions on the installation of sockets in a room of this type.

So:

Before you install a triple socket in an already working electrical network group, you should decide whether the circuit breaker can withstand the additional load. To do this, we need to calculate the possible rated current in the outlet. This is done by summing rated currents the most powerful consumers electrical energy that can be connected to this outlet.
If we know only the rated power of these devices, then we calculate the rated current based on the formula I \u003d P / U × cosα. Where I is the rated current, P is the rated power of the device (usually indicated in the passport or on the device case) and cosα is the coefficient the power of the electrical appliance (the instruction manual for the appliance should help you find its value, but if you did not find it, then you can take it equal to 1).
Now, summing up all the rated currents for a given group, we can check the compliance of the machine with these parameters. Often the machine needs to be replaced with a more powerful one. But if the socket is designed to connect low-power video and audio equipment, then this may not be required.

Note! According to clause 6.2.2 of the PUE, the maximum allowable rated current of the circuit breaker supplying the group network cannot be more than 25A. So, if you already have a 25A machine installed, then you will have to think about dividing the group or restrictions on connecting devices to this group.

Also, if installing a triple socket in an existing group involves controlling the cross section of the supply wire. Often, if the machine does not fit, then the existing wiring will not meet the new requirements. Therefore, again, you will have to think about the limitations of the connected load for this group.
And finally, you should decide, but is it possible to install an outlet here at all? It is impossible to mount the socket in bathrooms and storerooms. At the same time, there is an exception for bathrooms, which allows installation when installed in the power circuit of this group of an RCD.

In addition, if it must be installed on a combustible base, you should take care of its fire safety. To do this, mortgages under the outlet must be made of fireproof materials. Usually, steel products are used for this.

Installing a triple outlet

Assembling a triple socket

At the moment, there are a huge number of different sockets on the market. But either the price of them "bites", or they do not meet our requirements. Therefore, often a triple socket is assembled from three ordinary sockets.

How to make a triple outlet, we will now tell you:

To do this, we need three ordinary sockets, the nominal parameters we require. It can be one socket for 6A, the second for 10A and the third for 16A. The main thing is that they meet the above requirements. We also need an overlay for a triple outlet, which will create the appearance of a single whole.

We measure the required height from the floor, usually it is 30 cm, but you can choose any other height. At the installation site of the outlet, we draw a horizontal line parallel to the floor.
Now we remove the decorative covers on the front side of our single sockets and install a triple overlay in their place.
We put overhead boxes on sockets and apply our triple socket to the mark. We mark the place where the wall is shredded under the embedded boxes (see).

Note! If you use plastic embedded boxes with guides (they are also called mortgages for drywall), then it is enough to put on the mortgages and attach them to the installation site.

We drill the wall and install the embedded boxes. We fix them and install the sockets directly. If you did everything according to the size, then you should get a good triple socket. At the same time, its price is often significantly lower than that of similar stationary counterparts. Now it remains to connect.

Connection from junction box

The most common case is to connect the outlet directly from. It is used in 99% of cases when installing socket groups, and also in most cases when adding sockets to existing groups.

So:

First of all, we make the connection between the sockets. To do this, we need a wire with a cross section no less than the wire with which we plan to connect.
From the outlet to which you plan to connect, we make jumpers to the adjacent outlet. And from the next - to the third outlet. In this case, we attach the ground wire to the ground contacts, and the zero and phase wires to the power ones.
Now our triple socket in one socket is ready to be connected. But before you do it, you should relieve the tension from the group with which you have to work. In addition, if wires of other groups pass through the junction box, they should also be de-energized.
We open the junction box and determine the phase, neutral and protective wires of our group. If your electrical network is installed in accordance with the PUE standards, then the blue wire is zero, yellow-green is protective and the third is phase. If this is not the case, then we are looking for these wires by briefly applying voltage. The search methodology is described in other articles on our site.
Now we connect the phase wire in the junction box and on the outlet, then we do the same with zero and protective. It is important not to confuse the place of connection of the protective wire; phase with zero can be connected to any power outlet contacts.

After connecting all the wires and closing the junction box, you can apply power and test the performance of our sockets.

Connecting one outlet to another

This method is often used when adding a new outlet to an existing group. It is designed to reduce the amount of work associated with wall chasing and reduce the final connection price. And although it is rarely used, it also has the right to exist.

In order to make such a connection with your own hands, you should first of all assemble our triple socket, as described above.
The next step is to remove the voltage from the outlet from which the connection is to be made.
Then we open this outlet and then we act according to the established scheme. In essence, we install a jumper, as between sockets in our triple socket.
This completes the connection and you can apply voltage to our entire socket group.

Conclusion

Now you know how to install a triple outlet and assemble it from several single outlets. We hope this will help you in creating a comfortable electrical network for your home.

I would just like to note that additions to an existing network carry certain limitations. Therefore, they should be used only in exceptional cases.

In the modern age, when innovative technologies are developing by leaps and bounds, it is impossible to imagine life without electrical appliances that not only make life easier modern man, but are also an integral part of it. Even an inexperienced person who has never dealt with electronics before does not need to explain the principle of operation of electrical appliances, since everyone understands that their operation requires connection sources, the function of which is performed by a socket. What is a socket, you also do not need to tell. The house, as a rule, has sockets, and far from one, but it often becomes necessary to install a socket in case of repair activities or the operation of more electrical appliances. What to do in this situation? You can use the services of a professional electrician by calling him to your house, or you can comprehend the basics of installing electrical outlets and do it yourself. How to connect a triple socket in accordance with modern standards - we will consider in this article.

Socket and its varieties: an electrician's view

The socket is a specialized device designed to provide an absolutely safe contact closure, which results in an uninterrupted supply of electricity to electrical appliances. The design of the socket is represented by a plastic case, including the working part. The inside of the socket is represented by terminals to which springs for the plug and contacts are attached. Most modern sockets, including the triple grounded socket, are equipped with grounding contacts that reduce the voltage from all electrical appliances and increase the safety of the system. Modern market electrical appliances and their components offers the consumer several types of sockets, in the process of choosing which it is necessary to take into account the specifics of the operation of electrical appliances.

Despite the fact that the design of the socket, at first glance, is simple, it is necessary to distinguish between the following types of sockets:

C5 sockets are a standard Soviet socket, familiar to most residents of standard high-rise buildings. They are characterized by a square shape of the body, in the center of which there is a round cutout for the plug of the electrical appliance, as well as two round holes into which the plug of the electrical appliance is inserted. These outlets are not grounded and are also suitable for most older electrical appliances. Despite the fact that they are successfully camouflaged on the wall, their design and appearance leaves much to be desired;
C6 sockets, or, in other words, euro sockets are characterized by a more attractive appearance and, unlike C5 sockets that can withstand no more than 6A, the ability to withstand currents up to 16 A. In addition, for most modern electrical appliances, it is euro sockets that are used, which characterized by a wider fork hole. Another advantage of modern sockets is the ability to ground them, which makes such sockets safer.

However, contrary to the opinion of amateurs, the appearance of sockets is not their only difference. Sockets of all types have internal design differences. This is due to the desire to improve the design of the outlet, making it safer.

Important! Type C5 sockets are characterized by the simplest design, on inside which two adapter contacts are attached to a plastic or ceramic base, which are attached to the electrical wiring. The principle of operation of this type of socket is based on the closure of two transitional contacts, which occurs when you insert the plug into the socket.

The types of electrical contacts are also different. There are spring and spade contacts of C5 type sockets, while the latter are considered less reliable, due to their ability to lose their rigidity and subsequently spark when the plug is inserted into the socket. The reliability of spring contacts is due to the wear resistance of the springs that make up the design of the sockets, due to which such sockets can be successfully operated for several decades.

Triple socket: main varieties

The age of progress and the growing energy intensity of electrical appliances causes a constant increase in the popularity of triple sockets, which are becoming increasingly difficult to refuse in Everyday life. This problem is particularly acute in the kitchen, where we spend a quarter of our lives and make the most of many electrical appliances. As already mentioned, now reigns the age of innovative technologies that have not bypassed triple sockets, which differ in accordance with their modification, shape and size. Like the rest of the sockets (double, single), there are:

Triple internal sockets designed for hidden wiring;
Triple external sockets, so-called external sockets), characterized by a high degree of protection and the presence of a protective cover;
Triple sockets overhead and built-in;

As for modern modifications of triple sockets, they distinguish:

Triple sockets with grounding and without grounding;
As well as triple sockets with protective shutdown, which implies shorting the wires and turning off the outlet, while during installation ordinary socket simply knocks out the counter.

The design features of triple sockets, which have one power wire, allow you to connect up to three electrical appliances at the same time. Regardless of the modification of the socket, whether it be external or internal, in the process of their installation, the block assembly method, also called "combined sockets", is used. This method involves assembling and installing three separate outlets at the same time. To ensure convenience and aesthetic appearance of the design, experts suggest combining the outer frames of three separate outlets, replacing them with one common frame, which must be purchased separately. When buying an external frame, it is necessary to select it in such a way that the shape of the inside of the front panel matches the shape of the frame.

Important! Experts advise purchasing sockets that are characterized by a square shape of the inside of the front panel, as they are a more versatile model.

It must be remembered that manufacturers produce frames of various shapes and colors. More expensive models are sold separately: one box contains the inner part with contacts, and the other contains the outer part with a frame and a decorative cover.

Installing a triple outlet: preparations

Repair involves not only plastering, painting and wallpapering the walls, but also other tasks, the solution of which is also important. According to requirements modern design, the installation of electrical outlets must be carried out in accordance with euro standards, which imply their location at a height of 20-40 cm from the floor. This is due not only to convenience, but also to aesthetic beauty, since the cables of electrical appliances in this case will not be visible. When carrying out electrical installation work, it is important to be clearly aware that in case of incorrect selection of installation products, such as sockets and switches, a fire may occur. This issue is of particular relevance in the case of installing a triple outlet. This is due to the fact that any element of the electrical network is designed for a certain operating current, and in case of a discrepancy, an overload of the electrical network will occur and, as a result, overheating and burning of the contacts.

How to choose and install a triple socket? First of all, it depends on the type of wiring, which can be hidden or outdoor. If you plan to work with hidden wiring, you need to take the work more carefully. In this case, it is important to make sure that it is designed for a triple load. Otherwise, an overload of the electrical network may occur, which will lead to the need to replace the burnt wire, which is an extremely troublesome task.

Before connecting a triple socket, it is necessary to mark the place of its installation. If everything is much simpler with a single outlet, then all the constituent elements of a triple outlet should be located on the same level, since the slightest deviation from a single level will greatly “cut” the eyes. Having determined the installation site of the triple outlet, which, in accordance with Euro standards, should be located at a level of 25-40 cm from the floor, it is marked out, which is best done with a thick marker. If the layout for a single and double outlet is not difficult and involves drilling one hole in the wall, then things are a little more complicated with a triple outlet. To do this, set the building level and draw a horizontal line, after which mark the centers of the outlets, taking into account the distance between them. This is done as follows: mark the first center of the outlet and set aside half the width of the lining on the socket from it. This can also be done by applying the patch to the first center and measuring the second vertically located center, in accordance with the width of the patch.

Important! So that when installing a triple outlet there are no problems with cable routing, experts advise installing it where a single outlet was previously installed.

If it becomes necessary to lay wiring in a new place, it is necessary to apply vertical and horizontal lines to the wall (they must be straight!), As oblique and curvilinear routes will further complicate the process of finding and repairing wiring damage.

How to install a triple socket box?

Experts recommend installing a triple socket in one socket box, which is a block with three sockets located on a single frame. If you use three single sockets as a triple socket, which you install in parallel, experts recommend using single sockets. Due to the fact that the installation of a single block of three sockets is similar to the installation of a single socket, the installation of three sockets in single sockets will be considered below.

If you plan to work with brick or concrete walls, before starting work, you need to prepare the following materials and tools:

Perforator;
Specialized nozzle, which is a crown with a diameter of 70 mm, equipped with carbide cutters;
Voltage indicator;
Curly and straight screwdriver;
A hammer;
Chisel;
Medium and narrow spatulas.

Before installing a triple socket, take a puncher designed for concrete wall, or a drill for a brick and drywall wall, as well as a crown for socket boxes. The drill must be pressed against the centers of the sockets marked earlier and carefully start drilling holes until the crown rests against the wall. After that, it is pulled out and drilling is completed.

After you have drilled the holes, take the socket and squeeze out the number of holes on its back, the number of which corresponds to the number of cables that go into it. For a triple socket, this number is 3 pieces, and therefore, it is necessary to squeeze out three holes.

Important! When working with bricks and especially drywall, care must be taken and care must be taken as these materials tend to crumble.

Also, it is important to remember to drill two wire holes between the three cable holes. For these purposes, select a drill diameter that matches the diameter of the small corrugation into which the wires are inserted. Experts recommend using a corrugated pipe, but often it can be abandoned. If you install a socket in a plasterboard wall, the cable in the corrugated pipe must be thrown along the mounting profile.

How to wire a triple socket?

The wires must be connected in accordance with the parallel scheme, which implies that two wires are connected to each wire from the shield, coming from additional wires going to the second and third sockets. By using indicator screwdriver it is necessary to determine the phase and zero, after which the electricity in the shield must be turned off. Next, the wires are twisted, while remembering that for reliable twisting, experts recommend using specialized contact tips, which must be inserted into the socket clamps and screwed on. After the first twist, the wire is thrown onto the second socket and its socket is inserted through the hole in the back cover. A similar action must be performed with the third hole. After you have done this, all three sockets are ready for installation.

How to fix the socket?

Having prepared a mixture of alabaster with water, the holes drilled in the wall are coated with this mixture and socket boxes are inserted into them. Experts recommend making the mixture thicker, which will speed up the setting of the alabaster. If you see that the sockets are falling through, add alabaster, and if they stick out, they are tapped with a hammer.

Important! Despite the fact that this event seems quite simple, it must be treated with due care and put all the sockets on the same level, for which it is necessary to use the building level. In addition, it is important to keep an eye on the top screws, which should be located at the highest points of the socket and hold them. After you have installed the socket, you need to leave it until the alabaster is completely dry, which will take 1-2 hours, and then proceed to connect the socket.

How to connect a triple socket?

Recall that we connect a triple socket in three sockets. In this case, the connection is carried out in accordance with the parallel circuit. It is important to know that there are sockets that are connected in series through a loop. They are not recommended to be used to connect several electrical appliances at once, characterized by high power consumption. In this case, the socket is connected according to the diagram attached to the socket. In the case of our socket, all wires must be connected to its clamps and we press them tightly with terminals and screws, depending on the type of socket. Then the wires are twisted inside the box, after which the central part of the outlet is installed. In order to correct its level during the installation of the outlet by baiting the screws, lightly tap the metal case to level it. Then tighten the screws. After installing the central part of the triple socket, install the decorative overlays.

We can say that the sockets are installed and ready for use. To verify this, you need to check their performance by turning on the machine. To turn on the outlet for the first time, it is not recommended to use complex electrical appliances, preferring a table lamp.

Safety instructions for installing a triple socket

Before starting electrical work, be sure to turn off the electricity, and then make sure that the electrical network is broken;
In the process of work, it is necessary to use only special tools with insulated handles;
If you have to work with electric wire large length, carefully lay it in the wall or cut it to the required length;
If it is necessary to build up the wire, it must be soldered, and not twisted;
When installing the socket into the wall surface, it is important to monitor the density of its installation and insulation;
It is necessary to use equipment and wires rated for rated power and current and intended for electrical work.

By following these simple rules, you will be able to carry out electrical installation activities related to connecting electrical outlets as safely and efficiently as possible.

How to connect a triple video socket

Before wiring in new apartment or before replacing wiring during a major overhaul, any owner faces a choice of how many and which outlets he needs to install in each room. AT modern apartments outlets are rarely installed one at a time, usually two, three, and in some cases even four electrical outlets are placed side by side. For example, it is better to install 3-4 sockets at a workplace with a computer, otherwise you will not be able to do without an extension cord.

Practice shows that there are never too many outlets. If we need to install two sockets side by side, then we have a choice - to install two single electrical sockets in a two-gang frame or one double electrical outlet. The Florence series features double rosettes and multi-gang frames, so both options can be implemented. What to choose?

Double sockets are designed to instead of one old socket, one double socket could be installed into an existing socket. This allows you to double the number of outlets during the redecoration of the apartment. For this, double sockets were developed.
The price of a double socket is less than the price of two single sockets in a two-gang frame, we will see this on the example of white or beige sockets of the Florence series.

1. Calculation of the price for two single sockets in a two-gang frame

2. Calculation of the price for an alternative option - for a double socket

It is possible to mount the wiring so that powerful electrical appliances are connected to each single socket, i.e. so that a current of up to 16 A flows through each. But for this, it is necessary that the sockets are either powered through two separate lines with cables of the usual cross-section for connecting sockets (2.5 mm2), or powered in series through an oversized cable. As a result, it is possible to ensure that the total maximum current, which can flow through two single electrical outlets would be 32A. This cannot be done by mounting a double electrical outlet.

Summing up, we can say that double sockets are indispensable if we are faced with the task of increasing the number of sockets in pre-installed sockets. This is mainly true when replacing sockets in the process of redecorating, if the wiring is not being replaced with the installation of new socket boxes. Single sockets under a multi-gang frame look more aesthetically pleasing than double sockets and offer more freedom of choice. This option is suitable for an overhaul of an apartment with a replacement of wiring or for arranging an apartment without finishing in a new building.

Electrician's blog>Quadruple socket etude

At the SE themed event, which, alas and to my great regret, the author was forced to leave much earlier than planned, the novelty, wow wow, hot, series was once again presented Etude electrical installations Schneider Electric and in one copy was expropriated and carried away by the author to the bowels of the editorial office of the blogelectrician.

What they won’t tell you about the sockets in the store - which ones to choose Legrand or Schneider Electric?

The novelty is a square rosette with four posts.

It is simply incredible, but everyone who has seen this, at the request of the workers, a long-term product, if, of course, they are familiar with the attempts IEK sell all kinds of sockets and switches, almost unanimously recognize the novelty of Etude as a socket of the series Brix.

However, this is only a first approximation.

A more substantive acquaintance, for which it is enough even just to take the socket in hand, places accents as it should.

Etude does not compete in the market with Brix om, carried Turkish Chinese products, and with LegrandQuteo, well, and perhaps that Belarusians.

An etude based on mechanisms LEXEL produced at the Potential factory from plastics with demonic names. I'm afraid I won't be able to pronounce their names, and, to be honest, I'm simply afraid to do so. Actually, a young Belarusian specialist in the related field, here at this link, not only voiced, but also demonstrated clearly, including the impact on a fragile body. 🙂

So, the quadruple socket Etude:

Quite thin, at least the one at my disposal, well, in the photo, without curtains and a grounding contact.

The socket can be screwed to the installation box for flush-wiring mechanisms, which greatly expands the possibilities of application, for example, in panel houses when you want more outlets, and the budget clearly hints that it’s not now and not here.

And with such an outlet you can 🙂

And, of course, everything is also prepared for cable channels.

The socket consists of two and a half mechanisms that are not only non-separable but also pre-charged with wires.

Any home, such as renovation or construction work, is almost impossible to imagine without sockets. Consider the basics of their installation and connection.

First of all, turn off the power in the room where the sockets will be inserted.

After disconnection, it is necessary to additionally check the absence of electricity. Then prepare subcontractors and install new sockets. Wires must always be accessible.

Installing a new socket

Installation begins with disassembly of the cue - the outer shell from the inside.

Then the claws cut off the excess wire. In our case, the length of the wire should be at least 10 centimeters - this is enough for a comfortable and most convenient installation. In addition, at each end, the wire insulation is removed by about one centimeter.

Wire stripping:

Installing Consumer Connectors

Before installation, specify their number and location.

Installation conditions directly depend on the location of electricity consumers, which are very difficult to move - TV, refrigerator, computer and others. In such places, a block of 2 to 5 electrical outlets is usually installed so that additional electrical devices can be connected. This solution is much better than using different extensions and plugs that have an extra connector at the output, which significantly reduces the life of the socket.

Block parallel connections(with loop):

Connector wiring diagram - with a loop

You also need to consider sockets for temporary devices - a charger, an iron, a laptop, a vacuum cleaner, these are equipment that can move around the house or apartment.

These rooms are characterized by high humidity, which adversely affects the socket contacts.

Triple Connector: Installation Features

At best, at worst, it will become useless - you may be injured. If you still need to install this battery in such a room, for example, it is better to use a special protected electrical outlet for the boiler.

In damp areas, electrical outlets must be IP 44 protected.

They are located at a distance of 0.3-0.8 m from the ground in places of maximum access to consumers and with the possibility of their quality service. The distance to electrical appliances should not be too large so that the cable can hang freely and not be stretched.

Mounting types

The method of fastening the nest depends on its design, the material on which the wall is made, and the type of cable used.

If installed in plastic boxes, outdoor outlets are often used. The accessories are attached by means of joints on a concrete or brick wall or with self-tapping screws on drywall.

If the wiring is in the concealed type, sockets of a different shape are attached to a special part of the wall installed in the wall.

Attaching the socket holder to the junction box with a screw connection:

The latter elements also vary in different designs, which depend on the material on which the walls are based.

If the extension is made of dry walls, then it makes holes in accordance with the dimensions of the box attached to the drywall with special screws. Then connect the wires and place the electrical outlet in the box.

Installing grooves in a drywall wall

A wall-mounted outlet with a higher power, such as brick or concrete, it is necessary to use a special nozzle crown, which carries an annular groove in the size of the wall of the room.

Then only the agent is removed using a perforator or chisel. Mounted niche and box installed. Mounting and fixing sockets are similar to the plaster type partition method.

Installing an additional heater on a hard surface:

Location of points

To optimize the performance of your hair dryer, electric shaver and washing machine, the bathroom has a lot of nests.

In a standard room you need at least 4, while in a hallway one or two is enough. To protect a person from defeat electric shock on the power line, it is necessary to install a residual current device.

Risk of system damage without RCD:

All connections to the client group should be made slowly - the durability, efficiency of points of sale and the safety of residents of a house or apartment depend on the regularity of the operation.

Connection according to wire color

For convenience when working with wires, they are color-coded in standard colors to identify their purpose.

Blue is used for the neutral wire, white for the phase, and yellow-green for the floor.

Color Compatibility:

If you want to know which wire is connected to a certain terminal, you can start connecting.

The end of the remote wire is inserted into the socket and securely fastened with a screw.

When you connect all the wires, the socket is installed in the glass and attached with special clips.

Then the outer cover is on top.

Installing the outer cover:

The cover is located on the inside of the socket and is tightly screwed on. Basically, the connection is complete. You still need to check the correctness of the work done.

triple sockets

triple sockets allow you to connect to three consumers in one place. These connectors have one power wire. In most cases, the external and internal connectors use a communication method or a so-called connector. This method consists of the fact that an assembly is made up of three or more separate selling points.

External visible elements of the triple socket

For convenience and aesthetic appearance With this design, the outer frames of the individual outlets are replaced by one common (sold separately) frame.

When you buy a frame, you should pay attention to the suitability of the shape of the inside of the socket front panel and the shape of the frame. It is recommended to buy sockets with a square inside plastic panel (shown on the right).

They are more versatile in terms of options and installation instructions. Although this is the taste of the owner (buyer).

This triple mount frame has four outlets for socket covers, but the angles of the corners are not the same as for the frame on the right side.

We must not forget that frames are available in various shapes and colors.

More expensive connectors and switches are usually sold separately: in one box the inner part with contacts and in the other box the outer decorative cover with the frame. They produce outdoor outdoor parts different colors and forms.

In the case of external connectors, they are specially designed (but not widely used) that can partially bite part of the case and then form a triple assembly nice and carefully.

Installation elements of a triple socket.

In addition to the special external elements for the triple socket, mounting boxes are also used.

This part is in the wall and is usually invisible to users.

Brick and concrete brick boxes

Composite boxes are either cast-in or interlocked to ensure accurate and secure assembly of the built-in part.

Strip boxes

For hollow walls (cladding, drywall) there are also 3-gang mounting boxes.

All this applies to quadrant, penthouse and other multi-slot nests.

Hollow wall boxes can be used in solid walls (bricks...), you can remove the clips at the same time

The position of the plugs (connecting holes).

When installing and using three or more connectors, pay attention to the location of the connectors.

It is recommended that these holes run along or at an angle to the nest (see below). A transverse position (as shown in the figure below) may make it difficult to attach the side plugs of electrical devices.

When using devices - devices for temporarily connecting several consumers to one connector, you must be very careful.

With this connection method, there is an additional mechanical and electrical load on the pins of the main socket, which can cause an accident.

The main cause of unusual events is the decoupling of connector pins. In the event of poor contact, the connectors and plug connectors become very hot.

At the same time, they oxidize and condense, which leads to even worse contacts and strong heating in subsequent connections. The socket will burn out in the future. There is not much power here.

The figure shows a dissolved extension plug, for which a 1600 W hair dryer was connected.

The hair dryer worked for about 10 minutes. And the main problem was the poor connection of the plug to the socket. First insert the fork with thick end caps and insert the fork with thin stems.

More reliable in this case, in my opinion, is a multi-stage socket with connectors of different standards (thickness) included in the "own" holes.

For example, on the left side only plugs with thin rods are inserted, on the right - thick ones (evrovichki).

Also note the location connecting wire inside the assembly.

In some cases, it may be located under the break terminals on the inside of the socket. In this case, the insulation of the wire is destroyed by a possible short circuit of the conductors.

To connect sockets, it is desirable to use a solid wire with a cross section of up to 2.5 mm square (for example, VVG-1 3 × 2.5). Thick wires for connecting to the power supply are problematic - it simply does not fit into the terminal hole of the terminal.

Wire 3x2.5 VVG-2, although the cross section is the same as 3x2.5 VVG-1, but the actual thickness of the conductor in VVG-2 is due to the greater difference between the individual wires of the bundle.

Wire VVG 3×2.5 allows you to transmit power up to 5 kW at a voltage of 220 V.

Which usually means the total allowable power that RES provides for an average house, apartment.

Installing triple sockets

Installation of hidden triple sockets in a brick wall.

Consider, for example, the completion of electrical work in a newly built building with walls.

Basic steps for installing triple sockets

The study of the electrical circuit
Marking the location of electrical points (installation points of sockets and switches, junction boxes)
Chasing and laying wires
Installation of boxes for connectors and switches
Installation of electrical outlets, switches and other connections.

There are several cable routing options.

Chasing at the bottom of the wall - as in the picture.
This option was chosen due to the lack of a floor, it will not be difficult to install knitted plates.
If the floor, you can put the wires in a special base with built-in cable channels.
This method is also used in residential apartments.
In the absence of a special move, you can place the strokes below the feed plate at the bottom of the wall that you take for a while. (Also in pre-existing areas.) Be careful not to damage the wire by attaching the bracket!

Adding a new socket to an already equipped residential area.

Beneath the existing (preferably low carrier) rosette with a sharp knife, remove the background.

We have expanded them on the pages. We turn the car into a braid. The same applies to the location of the new socket. Place the cable in the flange and under the base. We have led to a new connector. We are chasing the strobe. Lay wallpaper (after the plaster has dried). The seat is visible only after the story of its presence.

You can use ready blocks

You can use external remote access sockets.

When installing external (plug) connectors, pay attention to the back of the socket.

Installed external plugs with open back, which must be installed using a special patch.

There are also external connectors with a closed back.

This connector can be attached directly to a surface.

Switches and sockets

A retro-wired interior will look incomplete if you don't pay attention to a few more important accessories: retro switches and retro sockets. Switches and sockets for open wiring Villaris are a unique combination of European design of the first half of the 20th century, high-quality environmentally friendly materials and modern Spanish mechanisms.

Socket outlets

The peculiarity of retro switches and retro sockets is that most of them are installed on top of the walls without special installation boxes.

This eliminates the need to drill holes for an electrical outlet, which means that retro switches and retro sockets, in combination with retro wiring, allow you to lay an internal electrical network already after finishing work.
