The zero line, which is a ground wire system and a zero wire, can not be measured with a DU electric pen, unlike the live wire.
zhi to use the test dao pen display.
Use a pen to find the socket's live wire first connected to the socket, and then connect the remaining two wires, if tripped, the two wires are connected to the reverse "tripping is the ground wire and the neutral wire are reversed, and it is useless to adjust the fire wire and the zero wire in the place of the leakage protector".
The bulb is not lit because only the live wire is not made of the zero line, disassemble the light plate to find the position of the zero line and connect it.

Anonymous users2024-01-22I don't understand, the ground wire is connected to the wall, it should be a socket problem, and the zero line is leaking.

Anonymous users2024-01-21First of all, let me tell you that the leakage protector itself is connected to two wires, and there is no third one.
Probably an interstitial version.
The neutral line of the seat is grounded.
Use a multimeter to measure whether this wire is connected with the ground wire, and if so, you can only change the line.
Try it with other electrical appliances first to see if it also trips. If you still jump, it may be a matter of the line.

Anonymous users2024-01-20Now the air switch of the building bai room power line, socket du power supply and zhi lighting power supply is dao
Separately, the air switch of the lighting back power supply does not have a leakage protector, while the air switch of the socket power supply has a leakage protector, so the lamp will not cause tripping. From the phenomenon you described, the occurrence of such failures is due to the following reasons:
1. The working parameters of the leakage protector do not meet the technical standards and are too sensitive, resulting in tripping protection as soon as household appliances are used.
2. The wiring of all wall sockets in your home is in contact with the wall, resulting in the total amount of grounding leakage close to the standard limited by the leakage protector, as long as the household appliances are tripped for protection.
In my experience, the leakage protector of the socket power supply is eliminated, and all problems are solved. The cancellation of the leakage protector is not a big danger to our electricity safety, and the old buildings in the past do not use leakage protectors.

Any appliance plugged in that seat trips. Then you see if there is too much smoke from the neutral wire and ground wire in the socket. As long as it is a socket problem, repair the socket. Home lines are easy to do. It's just a matter of three threads.
There is a problem with the socket, the screws connecting the socket and the wire are loose, and there is a fire phenomenon inside. Open and close the main space in the room and tighten the screws.
In this case, it should be noted that there is a possibility of leakage in the socket. It may be that there is too much oil or that there is too much water. It is recommended to close the main gate during the day, and wipe the cover of the socket with a dry cloth after opening. >>>More
The refrigerator is generally not overloaded, this situation is generally the end of the line is virtually connected, according to U=IR, the voltage is constant, the resistance decreases, the current increases, and the refrigerator compressor starts with a large current, resulting in the circuit breaker overheating action tripping.
