Answer: Generally, this is due to overloaded circuits, weak breakers or defective breakers.
- A Circuit Breaker is rated to protect a defined ampacity, exceeding the rated ampacity may cause "tripping" of breakers.
- Breakers with a continuous heavy load or a load close to the circuit breaker rated value, can stress the internal workings of the breaker and weaken the trip mechanism. This is a common cause of nuisance tripping. Circuit breaker replacement and/or re-circuiting is recommended.
- Circuit Breakers can fail, I have yet to find an item that has never had a manufacturers defect. We check for that!
