The installation location of the switches is dependent on the design and the type of room. For lighting devices that are installed in rooms with high humidity, it is recommended to take out sockets and switches to neighboring rooms with optimal environmental conditions.
For a common room, switches and switches should be installed on the walls, from the side of the doorway at a height of about 1. 5 cm. With this option, the switch does not close the opening door.
In places convenient for use and depending on the room and its finishes are planned to install a socket.
The device should have a location at a distance of at least 0. 5 m from metal structures with grounding – heating, water and gas pipes. In the kitchens, the distance has no special norms. The height of the installed sockets from the floor has no standards for rooms and kitchens. The sockets above the skirting boards are installed from the floor at a height of 0. 3 m.
By the method of fastening, sockets and switches are divided into screw and shameless. Using a screw, make a clamp between the contacts of the plate. This fastener method is the most reliable for aluminum wires, since during operation they have the property of heating and then deformed.
As a result, a weakening of contact is obtained, a spark begins to appear and heating. But it is worth twisting the screw and everything is getting better. Copper wires are connected with a locking clip – a special terminal. Reliable, fast and simple.
By type of installation, the circuit breakers are divided for wiring hidden and open. If the wiring is open, then the switches and sockets are installed on sodmettes with a diameter of 60 to 70 mm and not more than 10 mm thick, on material made of wood, organic glass or textolite. These devices are attached to the wall using screws, and a hidden head or gluing KNE-260 glue.
Fasteners are used using plugs made of wood or dowels. Electric installations of products are attached to the shatter with 2 screws having a spherical head.
For the grounds that have the ability to burn, it is necessary to install special gaskets on the slicema, from asbestos having a thickness of 2 to 3 mm. After that, the ending of the end wire of the electrical wiring is connected to the clamps.
