Connection of a double outlet

How do you feel about your own home? Consumer or in a businesslike way? When water is dripped in the kitchen, and sparks fly out when light or use rosettes - it is not very pleasant and even dangerous to live in such a house. You can cope with many housework on your own if you arm yourself with the necessary tools and get acquainted with the rules of work. Today we will talk about installing a double outlet. This is simple, but very responsible.

Surely every person, even a child knows what is a socket and why it is needed. Without electricity, it is impossible to imagine our life and if the socket does not work, then turning on an iron, a hairdryer and a refrigerator will not work.

What is a socket

The outlet consists of several parts. The one that we see is the external building, and the “heart” or the working part of the outlet is hidden in the depths of the wall. The working part is connected to the electrical wires passing in the wall to terminals, which are additionally wrapped in several layers of island (for reliability and safety during operation). Everything is simple and clear if you look at the standard socket and connection diagram. But, as you know, the world does not stand still and with it everything around changes. So we can say about sockets, to replace standard devices for connecting electrical appliances to the electrical network more improved structures. To cope yourself with their connection, you need to know not only the scheme, but also the types of sockets. Let us dwell on this issue in more detail.

Rosettes are divided into such types:

• faling outlet - designed to connect to open wiring. It is installed directly on the wall on a wooden base (less often - plastic) in a specially designated place. Such sockets are outdated, they can be found in multi -apartment residential buildings “Khrushchevs” and “Stalinks”, as well as in villages and in dachas;
• a hidden or built -in socket is designed to connect internal wiring. The name speaks for itself - the socket is attached in a specially prepared recess and is connected to electric wires;
• the device with a clamping terminal is screw, convenient for connection, because the electrical wir is simply clamped between the plates and screwed with a screw. Convenient, fast and reliable;
• the keyboard clamp - you will have to fix the contact using a spring that is located on the terminal. If you press on a special key, then the plates are extended so that it is possible to connect, releasing the plate key, tightly capturing the contact wires.

If you decide to replace the outlet in the living room, then it is best to give preference to a socket with a clip and a screw.

If everything is clear with the type of connection, then when choosing sockets, you should pay attention to single and double sockets. For example, a double external outlet can be installed even in one nest (socket) or in different ones - niches designed to install several sockets. For example, a double inner outlet can be connected in both 1 and 2 sockets, which are interconnected or located near each other (on a jumper with conductors connected in parallel).

The purpose of sockets is also important when choosing this device. So, on sale you can see sockets for installation in the room, as well as on the street.

Types of sockets and their purpose:

• the socket for installation on the street - the case is protected from moisture and dust. According to the degree of protection, such a socket is marked by the designation: IP 55 - protection against water and dust. It is equipped with an additional lid so that water and garbage do not get into the fork nest;
• a socket for rooms with high humidity (baths, saunas, kitchen, bathroom) - are equipped with a body that reliably protects the rosette from moisture and drops of water. Marking of such a socket is slightly lower - IP 44;
• a socket with additional functions is a forking for a fork and grounding. As soon as you need to extract a fork of an electric appliance from a socket, pulling it behind it, the springs located inside the rosette housing are triggered and the fork easily leaves the nest. This is very convenient, and also extends the life of the outlet. Grounding - grounding contacts that need to be connected to the grounding conductor are displayed to the grocery case. Such sockets protect the user and electrical appliances from breaking currents that can “reach” the plastic case;
• closed sockets are indispensable for houses where young children live. In order not to install protection and each time the electrical appliance is turned on, not to extract it, and then insert it back, it is advisable to install a closed outlet. In it, the holes are hidden from prying eyes with curtains (they can be moved away when the electrical appliance is turned on). If the child wants to insert a nail or another item into the socket, nothing terrible will happen, the holes will remain closed, since the curtains open only while pressing;
• a programmed outlet - for turning on and off, the device is equipped with a timer that can be programmed for the duration of work. So, if you install the timer for 3 hours, after this time the electric device will independently turn off from the power. It is very convenient if, for example, in the morning in a hurry you forgot to turn off the forceps for curling hair or an iron.

And a few words about the design of sockets. Recently, these simple devices have changed a lot, you can choose a socket for the interior of the room, hide or vice versa, it is profitable to emphasize this important and indispensable element.

How to connect a double outlet

Let's first consider the standard socket connection scheme to have a general idea of \u200b\u200bthe scale of work:

• it is necessary to de -energize the electrical wire, for this you need to open the electrical panel and turn off the plugs (twist or lower the toggle switch down). If you do this for the first time, then this work is best done in rubber gloves;
• now you need to check if you did everything right and make sure that the current is absent. This can be done in a simple and banal way - to include any electric device in the outlet: a table lamp or a hair dryer. If the bulb does not light up, and the hair dryer does not turn on, then you can start work. Or do this: check the current with a special indicator;
• armed with a screwdriver, unscrew the plastic lid of the outlet to remove the mounting clamps and gently pull out the working part of the outlet;
• at this time, you can carefully so as not to damage anything, remove the old wires;
• if there is a socket (box in the wall), then this place needs to be well cleaned or replaced by the old box with a new one. It is best to put the basis for fastening the outlet on a alabaster or gypsum solution. In order not to damage the wires, it is best to pre -extract them;
• preparation of electrical wires for fixation-cut the wires to the desired length, usually 7-10 cm, remove the braid, clean the ends by a couple of centimeters with a sharp knife, if necessary, you have to steal the ends. Everything, now you can connect the wires to the working terminals on the outlet;
• we bend the wires, insert them into the box, then to “plant” the core of the outlet and attach it to the socket using screws. If your outlet has a different design - just bend your paws so that the working part of the outlet reliably “sits” in the niche and does not hang out;
• everything, we coped with the main work - then we need to install the frame, fix with screws and you can turn on the plugs on the shield to check the work.

Connection scheme for a conventional and double outlet:

Everything seems to be simple and understandable, but when it comes to business, it turns out that not everything is so easy. So, so that you do not have questions when connecting the outlet, these tips will help you quickly deal with the task:

• if there is no grounding wires in your house, then the work is slightly simplified, since in this case it does not matter how to connect wires (phase and zero) to the terminals. You just need to connect the wires without sharing anything;
• if there is grounding in your apartment, then the connected wires will not be 2, but 3. The task is somewhat complicated, since you need to understand which cable to choose and connect everything correctly. For ease of work, each wiring is dressed in a colored shell. The white, red or brown color of the wire is always a phase, black, blue or blue - zero, and green or yellow is the “earth”;
• what is the difference between an ordinary outlet and with grounding: the wire to the ground cable must be connected to the terminal with protruding parts (antennae), which go beyond the rosette body;
• connecting the wire to the clip of terminals (screw) can either simply stretch it between the two plates or wrap the ring clockwise, from the side where the screw is screwed;
• we clean the ends of the wires according to the rules. The most acceptable method is to use a special tool for removing the winding that does not sniff the wire. Not every owner has such a tool at home, so we will do everything well, but with the help of improvised tools. To remove the winding carefully, you will need a knife and pliers. First, with a sharp knife, cut the winding in the circular, carefully remove. If the wire is one -core, then the insulation must be cut as if you are going to sharpen a pencil. We do it as accurately as possible so as not to break the wire itself. The bare part of the cable must be sold out to extend the service life of the outlet.

Now that everything has become clear with the rules for connecting a standard outlet, you can start a more difficult task - installing a double outlet.

A double outlet can be with grounding or with connection directly without a grounding wire.

How to install a double outlet. Subtleties of work:

1. A double socket is a monolithic case with two main blocks. Such sockets of such a socket are also 2, but it must be installed in a regular socket.
2. The total current when connecting any electrical device should not exceed 10-16 A. If this condition is not observed for a double outlet, then it is better not to create such a situation and not endanger.
3. Before starting work, you need to prepare a place for installation of the outlet, think about where the electric cable will take place, remove the wires and install the sockets in advance in the wall (make recesses). In addition, you need to buy sockets suitable for the interior of the room.
4. Turn off the machines in the electrical panel (twist or lower the toggy down). We don’t stop there yet, we immediately check if there is a current in the outlet. The standard method of checking - using a special device - a milliammeter. If you didn’t have one, then you can simply include any electric device in the outlet and make sure that the current does not enter.
5. Now carefully examine the double outlet. It needs to be disassembled, unscrew the screws and remove the pad. You will see the heart of the outlet - or the mechanism. It is necessary to work with it, that is, correctly connect a double outlet.
6. We expose the wires for 1 cm. Using a sharp knife, remove part of the isolet so that the wire itself is not damaged.
7. The peculiarity of connecting a double outlet is that you need to connect 2 outlets to one wiring line simultaneously. We draw conclusions: we need to select 6 wires to connect one outlet to connect one outlet, and for the second to lay a train of 3 wires (main).
8. As a result of the work done, it turns out that the socket, which is closer to the current source, takes on the voltage by the train (then if the extension cord) transfers it further to the second source - that is, the second outlet.
9. When connecting wires, nothing needs to be invented, since the color marking of the wires is always standard. That is, if you see black (red/brown) wires, then it will be a phase, zero - blue (blue), and green or yellow - the grounding wire. We do the following: we connect the wires “zero”/“phase” to the extreme terminals, only the grounding wire (green/yellow winding) to the central terminal.
10. If you are afraid to confuse something, then use a special screwdriver with an indicator, she will show where which phase is located.
11. Having checked yourself, you exclude the fire of the wiring, a short circuit and oxidation of the wire metal.
12. The full electrical safety of the outlet can only be guaranteed if the wire is inextricable, and the connection was performed using the branch of electric wires.
13. If you did everything right, then at this stage you can tighten the screws and attach the outlet itself. To do this, firmly fix the working part in the niche, fasten the fasteners and only after that you can install the lining (decorative element).
14. To attach the decorative part of the outlet, use the pencil and with the help of the building level, designate the line on the wall. This is the only way to do all the work correctly and efficiently.
15. Since the lining is very fragile, while screwing the screws, do not fix them much so that the lid does not burst.
