Wiring: covert and overt

Hidden wiring in most private homes and almost all apartments wiring hidden. When installing the hidden wiring in plaster walls and ceilings, break through the shallow grooves into which fit the electrical wires. After completion of installation of wiring grooves render over cement mortar or alabaster. If the installation of concealed wiring is in a newly built house, you need in punching furrow disappears. First the wiring, the wires are fixed with nails hammered into the mortar between bricks or primazyvaniem their alabaster wall at several points, then made plastering walls and ceiling and the wires are under a layer of plaster. In the joints of wires installed splice boxes, which are hidden in all the twisted wires. Dividing box must be installed at the surface of the wall, flush with it. Closed box for safety reasons and aesthetic plastic covers. To install the outlets and switches use the same splice box. They are made of steel or plastic. Sockets and switches are used for mounting the same in the version for concealed wiring. Once installed, they practically do not protrude above the surface of the walls. For installation of concealed wiring using copper and aluminum wire in PVC insulation, copper - a section of not less than 1 mm2, aluminum - not less than 2.5 mm2. The apartments are hidden wiring installation is carried out in channels, pre-made concrete walls and floors. Therefore, living in apartments need to be very careful when switching various electrical wires and replacing switches and outlets. To replace or even grow conductivity, which you inadvertently broke some have to shoot down tile, you may have recently laid, or to the junction of the wires you do not get. Hot Wire Hot Wire is on the surface of walls and ceilings. For the installation uses copper or aluminum wire with rubber insulation, coated with PVC. You can also apply for installation of copper and aluminum wire insulated with a polyvinyl chloride, but only if the wire separating the base, separating one strand of wire from the other. Electrical wire open wire fastened on the walls and ceiling with rollers made of insulating material - porcelain. Each roller has an axis of openings through which pass through the nail, the fixing roller with assembly in the wires to the wall. The smallest section of wire used for mounting an open wire: copper - 1 mm2 aluminum - 2,5 mm2. Wire when mounting the horizontal part of the wiring on the walls are put in parallel lines of intersection of the walls and ceiling at a distance of not less than 100 mm and not more than 200 mm from the ceiling or cornice. The vertical part of the wiring (descents,) acted as the ceiling perpendicular to the plane. Around windows and doors lead to the paving of 100 mm from the edge of the door or window frame. Clips for attaching the wires are located at a distance of 50 cm from one another. Switches and sockets with open wiring not attached directly to the wall surface, and the special insulating pads, made of dry wood and called the accessory boxes. Escutcheon attached to the wall long screws, and to him are already using two small screws are screwed into the switch or outlet. Own switches and sockets to open posting differ from those intended for concealed wiring and appearance, and the way fixed to the wall, since because of the specific installation are not in the wall, and on its surface. In the basement of the house because of hazardous conditions (wet, conductive floors and walls), the switch can not be set, it is set on the kitchen wall. Now open wiring in homes is rare, but it's looking where. In the house with wooden walls other wiring to do is simply impossible.
