What should I do if the main switch of Jingyue apartment 1 unit trips occasionally? After tripping, the household power supply must be turned off to turn off the main brake.

Tripping is nothing more than short circuit or leakage overload. Turn off the power of a family and turn it on again. If this family has to cut off power every time, it must be that the indoor wires of this family are leaking or short-circuited, so it is necessary to check and repair the wires of this family, otherwise there will be potential safety hazards; If no matter which switch is off, it means that the total load of the household is too large, which leads to the overload trip of the switch. The total load is just in the critical state of switch tripping and occasionally trips. Some people can turn on the switch after turning off some electrical appliances. It is suggested to change the switch to a higher level. Of course, it depends on whether the load of the line design allows to increase the load. If the load of the line design is not enough, there is no margin. The switch will not jump when it is enlarged, but it will overload the line and be unsafe.
