Cables and wires in residential and non-residential buildingslaid on the shield with a power consumption meter, with safety plugs or circuit breakers under the floor, on the walls to the junction boxes where they are joined by twisting, or via terminals (electrical terminals).
From racpredkorobok electrical wiringto pave drugimraspayachnym rasklyuchitelnym or boxes that connect to a single machine or the same group and for circuit breakers, sockets, svetilnikam.Vypolnit rasklyuchenie possible without special education and work experience as an electrician, just follow these instructions.
Usually come to the apartment 3 - 4 groups (includinga separate group that comes on electric stove, which paves independent cables or wires). Thus, in case of damage to the line from the power supply is turned off only part of the building or apartment. Pay special attention to the proportional and uniform load distribution between the machines or safety plugs in the electrical panel.
Before starting work, you need to de-energize the line, on which work will be done by removing the plug or switching off the machine.
As a general rule, establish a junction box for each room in case of a significant distancing sockets can be installed more specifically on the outlet.
- Start the cables or wires into the box through the holes in the gaskets (for overhead boxes) or advance the knockout holes vkorobkah installed inside the wall.
- Secure the box to the ceiling or wall using 2 dowels hsamorezov or when the process of assembling, adjustment, or installation to cover its vzapodlitso to a wall or ceiling with concealed installation.
- Carefully remove the outer insulation of the cable to theentrance to raspredkorobku.Pri tselostnostvnutrenneyizolyatsii want to keep living. Accidentally damaged areas are well insulated by using electrical tape.
- Adjust the length of the wires or conductors, leavingmaximum stock, while taking into account the ability to put them in for work completion. Normally, leave a margin of about 15 cm. With a large number of wires in one raspredkorobkeih shortened to 12-10 cm.
- Strip the ends of the wires or cable conductors.
- Connect the conductors (wires) according to the scheme of work with pomoschiklemmnikov (electrical terminals), insulating caps PPE or twisting.
- Insulate the twisted ends of the insulating tape or screwed caps.
- Dilute to the side beams of the phase, zero,grounding wire, then carefully tuck the wires inside, to facilitate the task can be to push gently with a wooden handle of a tool.
- Close and zavintitkryshku.

All protective and grounding (marked on the chartlike PE, highlighted in yellow) wires and zero (in the figure labeled N, oboznachenysinim) interconnected by color, as shown in the diagram. "Earth" Explorer is not, if the two-wire wiring.
Phase conductors (shown in black and red) rasklyuchayutsya a bit more complicated if the wiring of the junction box is just an outlet, the phase also interconnected.
In the case where the wiring goes to the lamp withone-button switch (as shown in the figure), the wire that extends from the switch, connected to the phase running on the lamp (L in the figure for lighting), and the phase is attributable to a switch soedinitso all phase conductors (in the circuit breaker Lna). Must be 4 connections.
The allocation of the conductors on the lamp withdvuhklavishnym switch to it pave the four-core cable (2-phase switching conductors, 1 phase off, 1 zero, 1 "the earth"). In the case of a two-wire wiring, three-wire, so kakprovodnik "earth" is missing. Connect the phase conductors to each other, reaching to connect rozetki.Takzhe phase power supply cable, coming to the common terminal dvuhklavishnogo switch with 2 wires which go to the lamp bulb separately. Below predstavlenyskhemy desoldering dvuhklavishnogo switch without the "land."
All null and grounding conductors (if availablethe latter) are joined together. Inside the box you should have 5 connections (including connecting grounding conductors) .Nizhe presented skhemarasklyucheniya dvuhklavishnogo switch to "ground".
