Cabling
Open wiring is done on the surface of walls and ceilings. For the installation using copper or aluminum wire with rubber insulation, coated with PVC. You can also apply for installation Copper and aluminum wires with insulation of a polyvinyl chloride, but only if the wire separating the base, separating one strand from the other wires. Electrical wires open posting fixed to the walls and ceiling with rolls made of insulating material – porcelain. Each video has a shaft hole through which threaded nail that secures the roller assembly in a wires to the wall.
The smallest section of wire used for the installation of open wiring: copper – 1 m m , Aluminum – 2, 5 m m . Wires when installing the horizontal part of the wiring in the walls are put in parallel lines of intersection of the walls and ceiling at a distance of not less than 100 mm and 200 mm from the ceiling or eave. The vertical part of the wiring (slopes, lifts) performed perpendicular to the ceiling. Around doors and windows wire laid at a distance of 100 mm from the edge of a door or window frame. Clips for fastening wires are located at a distance of 50 cm from one another. Switches and sockets in an open cabling attached not directly to the wall surface, and the special insulating pads, made of dry wood and called the Escutcheon. Escutcheon attached to the wall a long screw, and to it is by means of two small screws fastened the switch or outlet.
Own switches and sockets to open the wiring different from intended to flush and appearance, and the method of attachment to the wall, since due to the specifics of installation are not in the wall, and on its surface. In the basement of the house because of hazardous conditions (wet, conductive flooring and walls), the switch can not be set, it is set on the wall kitchen. Now open wiring in homes is rare, but it depends where. In the house with wooden walls to the other wiring is impossible.
