How to Troubleshoot Unexpected Circuit Breaker Tripping

Circuit breakers are designed to protect an electrical circuit from damage due to overcurrent. When a circuit is overloaded, the circuit breaker will "trip", switching off power to the circuit. Unexpected tripping of circuit breakers can be frustrating and disruptive. This article provides a comprehensive guide on how to systematically troubleshoot and resolve the root causes of unexpected circuit breaker tripping.

Common Causes of Unexpected Circuit Breaker Trips

There are several potential root causes for a circuit breaker unexpectedly tripping. The most common causes include:
