Reasons and detection methods for wall switch sockets that cannot be energized normally

Dec 08,2022 / BY DEVELOPERS
Wall switch sockets can be seen everywhere in life, and they are all concealed, so if there is no power supply, how should we solve it?
The detection method of the wall switch socket without power is as follows:
1. Check whether the neutral wire connector is short-circuited. First, disassemble the socket panel to see if there is any problem with the connection. You can lead a neutral wire to the socket from the normal working socket. If it can be powered on normally, it means that the original neutral wire is burned. If it is broken, the original wire should be removed and a professional electrician should be re-wired.





2. When the electric pen is tested, if the light is on, it means that the live wire is energized, and it proves that the neutral wire is disconnected, which will cause the socket to have no electricity.
3. Check whether the elasticity of the positive and negative contacts is good, and whether there is any abnormality in the contact between the shrapnel in the socket and the plug when the plug is plugged in.
4. The live wire has power, but it cannot be energized normally. At this time, it is also necessary to check whether the neutral wire is open (missing zero)
