During the use of the small power distribution unit, the following problems may occur:

Short circuit fault: Due to the short circuit of the wires in the circuit, the current is too large to exceed the design capacity, which may cause the small power distribution unit to trip or even cause a fire.

Overload problem: When the circuit load exceeds the rated capacity of the small power distribution unit, the current is too large, which may cause tripping or equipment damage.

Leakage problem: Leakage refers to the abnormal flow of current from the line to the ground or other unexpected paths, which may lead to the risk of electric shock, and the fault needs to be eliminated in time.

Overvoltage problem: When the power supply voltage of the grid exceeds the rated voltage of the small power distribution unit, it may cause damage to electrical equipment and even cause a fire.

Wiring problems: There may be problems such as loose, loose or wrong wiring, which will lead to unstable circuits and even affect the normal operation of other equipment.

In order to avoid the above problems, it is recommended to check and maintain the small power distribution unit regularly to ensure its normal operation and to have any malfunctions dealt with by professionals.
