The first reason: because the overload protector's heavy load exceeds the rated load, it is an overload protection trip;

The second reason: because some electrical appliances are grounded and tripped due to leakage protection; you can gradually plug in or turn on the electrical appliances, and when you turn on a certain electrical appliance, you must first check whether it has leakage current. Suspected, or high-power electrical appliances, the load has accumulated to exceed the rated load;

The third reason: Check whether the leakage can turn off or unplug all other electrical appliances, and turn on this piece alone. If it is turned on normally, it means that it does not leak electricity, and if it also trips, it means that the problem lies in this piece of equipment;

The fourth reason: If there is no leakage device, it is a load problem. You can first see how big your overload protector is (also pay attention to the allowable load of the meter), and then convert the total amount of electrical appliances you are using. Power, (refrigerators and air conditioners calculate the power based on whether the compressor starts or not), if it is indeed overloaded and cannot be adjusted to avoid it, it is necessary to consider the expansion of the meter and the replacement of the air switch.
