What are the situations of small power distribution unit tripping? How to solve it?

Small power distribution unit tripping usually has the following situations:

Overload: When the load connected to the circuit exceeds the load capacity of the distribution box and circuit design, it will cause overload tripping.

Short circuit: When a direct connection occurs between two conductors in a circuit (usually live and neutral), it causes a short circuit trip.

Leakage: When the current passes through the ground or leaks to the ground, it will trigger the leakage protector, resulting in leakage tripping.

Unbalanced load: When the electrical load in the home is unbalanced on different phases, it may cause the phases to be different, triggering a trip.

Solution:

Check the load: confirm whether the use of electrical appliances in the home exceeds the load capacity of the distribution box, reduce the load appropriately or increase the appropriate power supply.

Check electrical appliances: Check whether there is a short circuit in the electrical appliances in the home. If there is any damage or the circuit is aging, replace or repair it in time.

Leakage detection: purchase leakage protectors, regularly check and repair leakage problems.

Load balance: Reasonably arrange the use of household electrical appliances on different phases to avoid problems caused by load imbalance.

If the above methods cannot solve the trip problem, it is recommended to contact a professional electrician to check the distribution box and circuit to ensure safe and stable power supply. Electrical and electrical problems require professional repairs and adjustments. Please do not try to repair the circuit at will, so as not to cause greater safety hazards.
