Wiring

Scheme raskrucheny or connecting electrical cables in the junction box

Cables and wires in residential and non-residential buildings is diverted from shields to counter energy consumption, safety plugs, or circuit breakers under the floor, over the walls to junction boxes where they are connected by twisting or using terminals (electrical terminals).

From rasprodavalos electrical wiring are laid to dragonbane or resolutely boxes that connect to one machine or one group and the switches, outlets, fixtures.To carry out wire connections without special education and experience as an electrician, it is sufficient to follow the given instructions.

Usually come to the apartment 3 – 4 groups (including a separate group that comes to the kitchen, which is laid independent cables or wires). Thus, if the damage is on the line from the power supply is turned off only part of a 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 it is necessary to disconnect the line, which will be carried out, removing the tube or turning off the machine.

As a rule, install one junction box per room, in case of significant separation outlets may be installed, especially on the outlet.

  • To have cables or wires into the box through the seals in the holes (label the boxes) or through pre-made holes korobkah mounted inside wall.
  • Secure the frame to the ceiling or the wall using 2-samorezov or dowels when narodnom way to install it or to cover her zapodlitso with the wall or ceiling when flush mounting.
  • Carefully remove the outer isolation of the cable to the AUX in input.It is necessary to keep of celestenaturaleza lived. Accidentally damaged areas well insulated with electrical tape.
  • To adjust the length of the wires or lived, leaving maximum headroom, while being able to put them in after work. Usually leave a margin of about 15 cm With a large number of wires in one rasprekrasnoe shortened to 12-10 cm.
  • Strip the ends of the wires or of the cable cores.
  • To connect the conductor (wire)according to the scheme of work in pomoshchnikov(electric terminals), an insulating PPE caps or twist.

  • To isolate the twisted ends with electrical tape or screwed insulated caps.

  • Dilute to the side beams of the phase, zero, ground wiring, then carefully lay the wires inside, to simplify the task you can gently push with a wooden handle of some tool.

All the protective or grounding(the diagram is labeled as PE, highlighted in yellow) conductors and a zero (in the figure marked N,will oboznacheniya) connect among themselves by color, as shown in the diagram. Explorer“earth” not if wiring two wire.

Phase conductors (shown in black and red)razlychayutsya a little more complicated if respecatable wiring only goes to the outlet, the phase is also interconnected.

In the case where the wiring goes into the lamp with one-button switch (as shown in the figure), the wire that comes from the switch, connect the phase going to the lamp (figure L for lighting), and the phase that comes on the switch, soedinilis all phase wires (the diagram Lна switch). Should be 4 connections.

In the distribution of conductors in series with the lamp switch before him lay the four-core cable (2 phase cores enable, 1 phase off,1 zero, 1 “ earth”). In the case of two-wire wiring–three-wire, so cukrovarnicka “earth” missing. Connect the phase conductors going to the outlet.Also, connect phase power cable coming in on the common clamping series circuit breaker, 2 wires which go to the bulb of the lamp separately. Below predstavleniyami desoldering series switch without “land”.

All zero and the ground conductors (if available) connect together. Inside the box you should get 5 connections (including the connection of earthing conductors).Below are shemalescreen series switch“land”.

Attention! Before connecting the supply voltage again carefully to check the connection. In order to avoid short-circuit all connections must be made strictly according to the scheme, the insulation must be undamaged, place twists securely enclosed or secured with insulation caps.
