Who should I ask to repair the broken circuit at home?

The power company has a party member service team, which is free of charge. I just need you to provide materials. If there are no materials, you have to pay a part of the fee. Or find your own power-related maintenance personnel.

Jia Zhuang circuit construction should pay special attention to the following points:

A, the construction personnel should have a valid post operation certificate issued by the local labor department.

Two, the materials used should be national standard products, or with safety certification marks, to ensure the safe service life.

Third, the construction should strictly implement the specifications and process standards.

1. When carrying out all kinds of line displacement and transformation, the position of line terminal socket should be determined first, and the accurate position and size should be marked on the wall, and then the conductor should be led to the nearest similar socket. The lead-in method is as follows: If the socket is on the upper part of the wall, slot the wall vertically upward to the installation line where the decorative corner line is installed at the top of the wall; If it is in the lower part of the wall, slot vertically downward to the bottom of the skirting board. The depth of the groove is about15 mm. Put the wire and conductor into the protective sleeve, lie in the groove on the wall, smooth it with cement mortar and fix it in the wall. If the original socket is retained, it should be reinstalled in the original location; If it is not retained, it should be filled with bricks and leveled with cement mortar. When installing the skirting board, the wires along the ground are located inside the bottom of the skirting board. When installing the decorative wire, the wires along the top corner are hidden in the decorative corner line.

2. Code for Construction of Circuit Reconstruction Project. Slotting depth should be consistent, and slot line should be straight. After the control line pops up on the wall, cut the wall with a marble machine and make grooves by hand. When installing the line, it is necessary to add a protective sleeve, and the sleeve connection should be tight and smooth. The inside of the corner should be cut at the right-angle corner, and the arc interface should be cut at the cut side before bending installation. After the conductor is put into the casing, the conductor fixing clip should be used to fix it in the wall and metope first, and then plaster it for concealment or use skirting board and decorative corner line for concealment. When installing the socket box, first make a hole in the wall. After the wires are inserted into the box, the box will lie in the hole and be fixed. The wires are fixed to the panel, and the panel is fixed to the box. The installation method of the power switch is the same as the socket box.

3. Copper wires should be used and configured according to capacity. Not too thin. It is suggested that the air conditioning line diameter is 4 square millimeters; 2.5 square millimeter wire for socket; 1.5 mm2 wire for general lighting. When wiring, in addition to passing through the hollow floor, it must pass through the pipeline. Lighting wires and wires with different voltages such as telephone and TV lines should not be placed in the same tube; The power socket panel should be left zero line, right phase line and upper ground line, and cannot be connected wrongly; The neutral wire, phase wire and ground wire should be of different colors.

4. The wiring should use concealed pipes. For electrical wiring, PVC pipes are used to lay concealed pipes, and PVC grooves are used to lay open wires. Avoid wall cracks caused by gouging during construction and damage to wall structure. When laying, it should be changed according to the number of wires in the pipe. There should be no more than four wires in the same tube. It is forbidden for wires to occupy all the space in the pipe. Air conditioning, lighting and sockets should be controlled by branches, generally at least four ways. Lighting all the way, air conditioning all the way, three or four sockets. The advantage of this is that once a line has a short circuit or other problems, the power outage range is small and will not affect the normal work of other lines. The distance between the power cord and the telephone line and TV line should be more than 50 cm, and the pipeline should be fixed with the structure. Junction boxes shall be installed at all switches, sockets and lights. In addition, if the pipeline is too long or turns too much, a junction box should be set at a certain distance. Wire connectors are strictly prohibited in the pipeline. At the bend of the wire protection tube, a matching elbow tool or elbow should be used, and there should be no wrinkles. The distribution control switch should be configured reasonably according to the requirements of the specification. If the configuration is too small, it will be inconvenient to use, and if it is too large, it will not guarantee the safety of electricity use. Another point is very important, that is, the pipeline should be installed first, and then the conductor should be threaded, so as to avoid the phenomenon that the conductor can not twitch when changing the line in the future.

In addition, I want to remind you that when your home improvement project is completed, don't forget to ask the construction unit for a set of electrical circuit completion drawings to facilitate your future maintenance.
