How to install the electrical shield?

Before installing the switchboards,it is necessary to draw up a project, which will be used to distribute the transmission lines. Consumers are grouped by machine according to capacity. It should be noted that some appliances require better protection from short circuit, therefore, in considering the wiring, you must take this into account and mount separate highly sensitive machines for such devices.

By dimensions, the electric guard is calculatedaccording to modularity. One module is 18 mm. In other words, a single-phase automatic machine will be 18 mm wide, two-phase machine - 36 mm and so on. In this case, the use of RCD should be meaningful. Do not use a differential automaton to power the lighting or sockets. They are used for instruments of high sensitivity to earth faults. Such devices are rarely found in everyday life, so the RCD is not always suitable for installing home electrical wiring.

Shield electrical built-in type betterlooks like a cumbersome bulging structure, but for this you have to hollow the niche under the body in the wall. Some montors recommend the installation of a hinged shield made of a plastic box. At the same time, it looks rather elegant, and its installation is simple.

When installing the switchboard, it is necessary to arrange free access to the machines, so the structure should be placed in spacious rooms on free vertical supports.

Electric fittingsis installed with the help of anchors and special stamped holes for them. In the shield body, sometimes you have to drill holes yourself. When everything is ready for fixing, the casing is mounted, evaluated, it is fixed exactly, then it is removed. Then the machine is mounted on a DIN rail. In addition, you can separate the jumpers and prepare a place for cable entry.

If it is decided to install an electrical shieldbuilt-in performance, then you have to work, because, in addition to simply installing machines and fixing cables to them, you have to hollow out a niche in order to fit the shield body in it. But it's aesthetic and saves space.

Works on site preparation are betterto entrust to the specialist, since on the way of the bumper there will necessarily be armaments or old electrical wires. After installation, proceed to assembly.

If the installation is carried out in a niche,prepare the sleeve for cable entry into the built-in shield. This is done in several ways, however, deciding on the reconstruction of the wall, it would be wrong to put power lines somewhere on the baseboard or on the walls.

After everything is ready, it remains to establishthe shield is electric to the prepared place, and all necessary machines must already be installed in it, and the cable must be brought to the point of entry.

It is worth remembering that wiring around the apartmentshould be marked, and for greater confidence you can get rid of the veins. The shield should be earthed, as, indeed, the sockets, so it is recommended to throw the cable with the backup wires.

Installing machines for convenience is from left to right, from top to bottom. An introductory automaton is installed first, and further installation is performed at the current rating - from higher to lower.
