For attachment to the outlet box is equipped with strutting legs with jagged ends, with special tightening Screw these feet are divorced and run into the wall box. Before you tighten the screws are tight, you need to hand in these outlet in the box to two stops mounting bracket formed on the edge of the box. In modern models, the installation boxes provided smarting bovye socket screws, which flange socket is attracted to the box. Read more from Verizon to gain a more clear picture of the situation. Outlet should be installed so that the sockets for plug positioned horizontally. When laying power lines outlets directly to the height of their deployment setup boxes simultaneously used as switching: for each terminal is fixed at the same time and the transfer, and a lead wire. When mounting switch should be aware that live wire should be connected to the terminal sliding contact, and zero – to the terminal fixed contact.
If the switch two or trehklavishny, he has all the moving contacts displayed on the one terminal (for her and connect live wire), and the terminals fixed contacts connect two or three neutral wire. Zero sum up the wires from the switches for lamps (or groups of lamps chandeliers) as a phase, they must be connected to a central electrical contact holder. Wire is threaded from the contact, which is screwed into the lamp cap, is connected to the neutral wire. If you want a single point, multiple socket or power sockets and switches, you can use special installation box with adapters to integrate them into one unit. For switches and outlets, there are also frames, overlays, which combine two, three or four device into one unit – vertical or horizontal. Wiring junction boxes in each room can have one or more groups. Each group must be connected to your junction box (Or to the total, multigroup), which, as already stated, is housed in a room or hallway closer. Switching the wires can be carried out at the terminal block, although permitted and twisting. The correct twisting of wires (with subsequent isolation by tape or by using a commercially available insulating cap that fits over a pair of wires and twist them, turning the screw cap) provides a better contact than the terminal block with side clamp the wire. Such contact is not heated and does not spark. However, the twist is very inconvenient for repair or overcommutation.
