1. There is a phenomenon of "soft breakdown" in the "socket" circuit in your home. The method of judgment is to use a 500V megohmmeter to check the insulation between the "neutral line" and the "live line" after power failure, and the minimum insulation resistance should not be less than 0.5 megohms,
2. There is a slight leakage phenomenon in the "socket" circuit in your home. The inspection method is to remove the "neutral line" and "live line" of the "socket" circuit in your home, and then connect them to any other switch with the same capacity in the distribution box. If the switch no longer trips after closing, it means that there is a slight leakage phenomenon in the "socket" circuit in your home. If the switch still trips after closing, it means there is a "soft breakdown" phenomenon in the "socket" circuit of your home.
3. There is a problem with the leakage protection switch of the "socket" circuit in your home. You can try replacing it.
Finally, I have a piece of advice for you; Do not blindly listen to those who do not understand electrical engineering
Increase the capacity of the switch, otherwise there is danger. 1. Are there any electrical appliances with high loads?
two
If not, then there must be something short circuited It's a problem with the wiring. There may be a short circuit in some part of your home. Please have an electrician check it at home. That means there's a short circuit somewhere!!! Check the switch carefully for any faults, short circuits, or electrical leakage. I'm not sure if you changed the wiring during the renovation. If the cables were laid without protective tubes, this problem may occur. There are two possibilities for this problem: overload of the load; There is a short circuit in the circuit I personally feel that the biggest possibility is that there is a problem with the leakage switch, because you mentioned that the main switch also tripped. The reason for the main switch tripping is due to excessive current. If it is an electrical leakage, I won't tell you for a few minutes before jumping. It should be in an instant, between 20ms-40ms. Try replacing the leakage switch, it may be due to poor insulation inside^_^
My family has encountered a similar situation before. An electrician came and tightened the wire ends in the distribution box. Is it simple?! First, unplug all the plugs Then you pull off all the switches in the distribution box except for the main switch Then you closed each gate separately If that road jumps, it means the problem lies there Don't close the road that jumps like this The rest can be used Then find a professional to take a look If the socket trips even after being unplugged, it indicates that the load is not exceeded. Check if the trip switch is damaged, and then check if there is a short circuit in the circuit. Additionally, if the wires are aging and leaking electricity. Thundering is also related. Except for the main switch, all the circuit breakers should be turned off, and all electrical appliances should be stopped. See if the main gate will jump. Will: The main switch is broken, and the wiring in the distribution box is damaged. No: Try opening the circuit again, closing each circuit one by one. If the circuit jumps, it means the problem lies there.
