Home leakage switch, old trip, old electrician, teach you step by step

There is a leakage switch called an earth leakage circuit breaker . In short, the output current is not proportional to the output current (the current is not enough), and the current amplitude is not equal. It can be said that the current of the live wire and the neutral wire are not the same. In such a situation, please be careful to stay away from it and ensure personal safety.
Leakage switch tripping is mainly divided into three cases: leakage trip, overload trip and leakage switch tripping. If the leakage switch is damaged and the trip occurs, the power supply will be turned off if it is on, and the load will be turned off regardless of whether there is power or no power.
The performance of the overload trip is: after the load trips, the gate is not matched at all. The temperature of the circuit breaker case is not directly contacted by the hand. As long as the temperature drops, the switch can be closed. In this case, the overload is turned off. .
There are many sayings about leakage tripping. The most reassuring and reassuring is the discharge method. Unplug the power supply, turn off the leakage circuit breaker, and then use the split-switch method to connect to the leakage circuit. The leakage switch will be bounced off. You can determine which way you are, and then check which pipe inserter, or other electrical appliances, take the pipe socket of this switch, just remove all the electrical appliances connected to the socket, and then send them power. One by one, the power is turned on until the appliance is plugged in midway, and it is possible to eliminate which appliance is off. Such problems are generally not serious.
If the problem is serious, it is not a simple method to solve the problem. For those two examples, the air conditioner compressor leakage, the simple method of discharging is not easy to check, only when the compressor is running. Will trip. The other is the street light. When it rains, the lamp head will be wet and it will trip irregularly, which is very difficult to solve.
