Installation of electrical wiring is a rather laborious, complex and responsible matter. Therefore, you need to approach him with all seriousness. Before starting work, it is advisable to draw a scheme, given the future location of sockets, switches and lamps. The total power of the devices connected to one socket should not exceed 5 kW.
Wiring the entire wiring in the apartment must be carried out at the same time. The fact is that any twisting wires that are inevitable during partial installation repeatedly increase the likelihood of malfunctions in the future. For the input line, it is permissible to use the wire with a cross section of at least 4, 5 mm, for wiring in the apartment — 2.5 mm. Lines leading to sockets, switch and lamps can be made of 1.5 mm wires.
Wiring of the wiring is carried out in two ways — closed and open. When using the first method of the wire, stretch either to the final decoration of the walls with subsequent plastering, or after, but along the strobe — a groove specially arranged in the wall or ceiling. After completion of work, the groove is covered with plaster. In this case, the prices for installation of electricians will be slightly more expensive than pulling it in an open way.
The wires are opened in an open way either along alabaster pads or in special fire pipes. They can be corrugated or smooth. In the first case, brackets from the same wire are used for fastening, in the second clip. For the places of branches from the main line (to the sockets, switch, etc.D.) Provading boxes are provided.
The wires are usually pulled under the ceiling, retreating from it down 10 — 20 cm. From the room to the room they are drawn through through holes in the walls. At the same time, refractory metal tubes are used without fail. For very powerful household appliances, individual electrical wiring lines leading from the shield are provided. It is advisable to install auto switches on them.
As for the sockets, they are mounted at an altitude about a meter from the floor, the switches — a meter — one and a half. These elements are installed in the nests previously knocked out in the wall and covered at the edges of alabastr. With an open type of electrical wiring, sockets and switches are mounted on special gaskets.
During the work, it must be remembered that the qualitatively performed wiring in the apartment will allow you to use it without problems for many years. Various technology disturbances can lead to serious additional expenses and even in some cases — to the tragedy.
