There is a problem:
1. The main reason is that there are too many line connectors and improper handling of connectors. Some lines are too long. Some joints will be produced during the electrician's operation. However, due to technical limitations of some of the construction team's electricians, the wiring, insulation, and moisture-proof treatment of joints are not good, and disconnection, short circuit, etc. will occur.
2. To reduce the cost of cutting corners, the wiring for the concealed treatment is not sleeved.
3. The completed line was damaged by subsequent construction. If the wall line is interrupted by an electric hammer and the floor is paved, the air nail gun penetrates the PVC pipe or sheath wire.
4. The distribution line does not take into account the different rated currents of the wires of different specifications. The "small horse-drawn cart" causes the line itself to be overloaded for a long time.
5. Different lines go the same line. If the television antenna, the telephone line and the distribution line are threaded into the same casing, the reception of the television and the telephone is disturbed.
