Introduction to the fault inspection and solution of the circuit breaker in the Small Power Distribution Unit

The fault inspection and solution of the circuit breaker in the Small Power Distribution Unit are as follows:

Circuit breaker tripping: If the circuit breaker trips frequently, the circuit may be overloaded or shorted. First, check whether the electrical equipment exceeds the rated load of the circuit breaker. If so, reduce the load or replace the circuit breaker with a larger capacity. If it is not overloaded, the circuit may be short-circuited. It is necessary to check the connection of the wires and equipment to eliminate the short-circuit point.

Circuit breaker will not reset: If the circuit breaker will not reset, there may be an internal mechanical failure. At this time, no forced operation is allowed, and a professional electrician should be contacted immediately for inspection or replacement of the circuit breaker.

Circuit breaker heating: Abnormal heating of the circuit breaker may be due to overload, poor contact or aging. The power should be disconnected immediately, and the faulty circuit breaker should be checked and replaced.

Circuit Breaker Leakage: If the circuit breaker is leaking, it may be due to damaged wiring insulation or equipment failure. It is necessary to unplug the electrical equipment one by one and reset the circuit breaker to confirm the cause of the leakage, and then repair or replace it.

Remember, fault checking and repairs of Small Power Distribution Units should be done by a qualified professional electrician to ensure safety and proper handling of the problem.
