How to connect a telephone, computer socket: schemes

For the operation of electrical devices, you must connect to a local power network. Since you can connect the outlet with your own hands, it is not necessary to contact professional electricians with this problem.

Steps for connecting a simple outlet

To properly connect a computer or any other outlet (under a stove, refrigerator, power supply), you will need step-by-step instructions and a wiring project. The first step is to finish all the preparatory work. This is the wiring of the cable to the desired location, the organization of the holes in the wall (if the connection will be made using the built-in outlet) and the choice of the desired device type.

Step-by-step instruction:

1. It is necessary to disconnect the apartment or house. This is the first and very important step on which your safety depends. In most cases, an automatic machine is installed at the entrance to the room, which allows you to completely stop the supply of electric current. After that, using a special screwdriver, you need to check the voltage, when the power is turned off, it should not be. To avoid possible injuries, you need to work in rubber dielectric gloves;

2. Then you need to remove the old outlet box. It is attached with screw connections. Gently unscrew them and remove the screws to the side. For fixation, most boxes are attached with metal tabs to the protrusions in the wall. They must be carefully bent off, be careful, if they are handled carelessly they can break. Now you need to disconnect the power wires;
3. To ensure the maximum level of security, we recommend that you connect an earthed outlet to the shield. They are slightly different from standard sub-rosette in their design, they are primarily connected to grounding terminals, and after them the phase cable. Here, the earth wire from the switchboard is laid to the desired outlet and is adjacent to the protruding metal terminals;
4. If you have a model without grounding, then the work is carried out more simply and quickly. In most cases, the connection wires are color coded. Each of them needs to be cleaned a little - this will help make the cable more flexible. For this, up to 15 centimeters of insulation is removed;
5. After we connect the power wire to the terminals. For a denser and more durable installation, it must be connected to the contacts using a screw clamp. Screw the screw with a screwdriver, but do not squeeze it, otherwise the thread will fly off;

   

6. When connecting the outlet, you need to twist the wires into a ring, so they are guaranteed not to fly off the clamp screw. After all the terminals are once again checked for fastening, the device is inserted into the box;
7. Depending on the type of appliance, it can be installed on the wall or in it. The built-in is considered more convenient and safe in everyday use, but at the same time the consignment note significantly saves time at the preparatory stage.

When you insert the device into the socket outlet, make sure that there are no distortions, all ends should be at right angles to the wall. When everything is ready - just install it in place using the tabs and screws that hold the outlet in the wall opening.

Dual Model Connection

Now in most apartments modern double sockets are installed, which allow you to turn on several electrical devices at once from one point of the apartment. Their difference from standard models is a greater number of contacts.

How to connect a double or triple outlet Legrand, Vico (Viko), Schneider Electric, Makel:

1. When working, keep in mind that there are two pairs of contacts that can be located above and below, and on the right - on the left. Depending on the design, the connection principle changes;
2. The power cable is stripped and routed into two different current collector plates. If you connect everything to one, you will get a very dangerous connection. In the future, the installation principle is no different from the installation of a standard single model;
3. Also, sometimes a double outlet means a team in which you need to connect two and more single (if connected in series, then when the machine is turned on, a short circuit). For this, special jumpers are used to help branch the wire.

Turning the circuit breaker on

To save wire, many home masters use a circuit where you can connect a switch and an outlet to one junction box. This saves the number of cables and provides the ability to connect additional lighting or other electrical appliances under the lamp.

1. Power wires are wound into the junction box. Consider the example of color marking. The phase (red) and zero (blue) are entered in the box;
2. The socket is connected using the power cord to the network, and the zero of the device - respectively, to zero wiring;
3. All connections are made in parallel. Similarly, the phase supply of the switch is connected to the phase of the network and the same thing is done with zero. It turns out that the switch controls both the outlet and the lamp.

After all the cables are crimped and wrapped in a distribution box, it closes.

Connecting a TV and Internet cable

Now in each apartment there is one, or even more television, each of them must be connected to the electric network. How to connect a loop-through Internet (LAN Ethernet, HDMI) or a TV outlet Legrand Cat (Legrand), Lezard, ABB, etc. do it yourself:

1. They are connected by a loop. It should be noted that during the operation of this scheme the satellite signal may be lost, therefore it is worth discussing such a connection with your Internet provider;
2. The connection is almost the same as in all the options described above, but all sockets are connected as pass-throughs and only the last of them is final;
3. Each pass-through device has an output under the antenna and under the TV, or under the computer and router. Using these schemes, the signal gradually attenuates; in the penultimate one, it is the weakest;
4. The separation of wires is the same as that of dual devices.

In addition, you can also connect a computer cooler to an outlet for additional cooling of the PC.

Telephone line connection

For the phone to work, you need to connect a telephone jack. It is very easy to do:

1. Telephone lines use plus and minus labels. Plus is red, minus is black. It is advisable to take into account the polarity when connecting, because some phones otherwise simply do not work. To find out this indicator, you need to check the contacts with a tester;
2. Set the wires according to their colors and tighten with a screw clamp;
3. Close the outlet box and mount it in the desired place.
