Hurry!! Kneel and beg all of you, and ask the great god to be in a hurry!!

The reasons are generally as follows:

1. The total load of household appliances exceeds the power capacity of the switch. For example, if the total power consumption of an appliance running at the same time is up to 10kW, the circuit current can be reached, and if the rated current of the switch is only 30A, it will trip due to overcurrent protection. You can observe whether there are too many high-power appliances (air conditioners, instantaneous water heaters, etc.) turned on at home when tripping, if so, turn off some of the electrical appliances to see if it can be solved, if some are turned off to solve, it means that it is indeed caused by overload, and you can replace the switch with a higher current.

2. There is leakage in electrical appliances, and leakage protection. This situation is more dangerous, and it must be checked in time, especially the electrical appliances and wiring in the bathroom, kitchen and other places where the environment is relatively humid.

3. Overheating protection caused by aging of switches and poor contact. Replace it in time.

Either way, it's best not to replace it yourself, unless you know the principle of strong electricity very well, it is highly recommended to find a professional electrician to get it.

There are generally two reasons for tripping, one is that you have too much electrical equipment in your home, and sometimes the centralized power consumption is too large and overloaded. It is possible to replace the electrical switch with a slightly larger capacity. Second, it may be that the contact of a certain electrical appliance line in your home is not good, and there is an instantaneous short circuit, please carefully find the cause and eliminate the hidden danger.

If it was normal before, then it may be that the switch is broken, change it.

One is that the empty drive is broken, and the other is where there is a short circuit.

There are several reasons for tripping, you have to check the line at home, overload, short circuit, undervoltage, overvoltage, and leakage will cause tripping. If you can't find out why! It is recommended that you find a property electrician to check and deal with this problem.

Suggestion! You get a professional electrician! Help you.
