Professional Electrical Fault Finding Cape Town can be used to investigate the underlying problem.
5. Circuit Breaker Keeps Tripping
Circuit breakers are designed to interrupt electrical supply when a fault or abnormal electrical condition occurs.
If a circuit breaker repeatedly trips, repeatedly resetting it does not address the underlying cause.
Common reasons a breaker may trip
A breaker may trip because of:
Circuit overload
Short circuit
Faulty appliance
Damaged wiring
Loose connection
Faulty electrical component
Another electrical fault
If your power keeps tripping, professional fault finding can help determine whether the issue is related to an appliance, circuit, wiring or distribution board.
