The External transaction type is mounted along the wall. Wires are attached by special fasteners or are within the cable channels in the corrugation or the metal hose.
According to the rules of electrical safety, all wiring in a residential room should be three-wire, consisting of phase (L), zero (N) and earth (PE). The wires are allowed to use only with copper conductors. If the old house was repaired, then surely it held outdated two-wire aluminum wiring. The old cable should be pulled out of channels in the wall, then mount a new, modern power supply system.
For work on installation of electrical we will need the following tools and materials:
During the electrical installation in apartment or private house you should take precautions. First, do not connect the cable to the network during work with him. Secondly, it is necessary to wear protective devices:
Gates is allowed to make only horizontally or vertically. If the wall or partition has a thickness less than 100 mm, making vertical grooves closer than 200 mm from the edge of the wall is prohibited. The distance between the channels for wiring on the same wall should exceed 1500 mm. Corrugation should be chosen with such a diameter that it is several times greater than the diameter of the cable.
Taking a pencil, draw the places where you plan the installation of sockets, switches and junction boxes. Then you should identify places where there will be grooves, it is preferable to use a level for precise drawing lines horizontally and vertically.
Using a drill with a special nozzle, do the recesses for switches and sockets, and holes for mounting junction boxes.
Between the recesses for sockets and switches, follow channels, using wall chasers. These holes should be done so that the corrugated pipe can easily fit into the groove completely. The wiring should not protrude beyond the grooves. After work a power tool to make the grooves using a chisel and a hammer. Be sure to remove the resulting dust from the walls and floor before the next operation.
Lay the corrugation with wires inside into the prepared grooves, and then zashpaklyuyte wall and align their rule. Then you are ready to install junction boxes.
Before starting, do not forget to remove the top cover. In the wall the material is fixed with a small amount of putty. Once the box is securely held in the wall, insert a tube and secure them with nails, driven into a corner.
In the process of operation of the building may be open circuit in the wiring inside the building. If the wiring was not used terminal boxes, find the open will be much harder. If they do has been set, then the damaged wire is easy to calculate and replace with serviceable. You do not need to peel the Wallpaper and break the wall again.
After successful electrical installation in a private home or apartment start puttying the walls. After the desired amount of material applied, the holes plastered over, the excess solution, remove the trowel and flatten the wall rule. Monitor the work performed and attach to the wall level.
During the installation of electrics in the cottage or any other building required to carry out the stranding of the wires to each other according to the same rules of the SAE. There are only 3 types of cable connections:
During the installation of the electrics in the room besides the machines, we need to think about the installation of fire protection devices, RCD installation, the leakage current of 100 mA. In rooms with high moisture (bathroom, kitchen) you need to install an RCD with leakage current up to 30 mA.
During the work related to electricity in residential areas, use only high-quality wire, such as cable VVGng and its modifications.
