Did the circuit breaker trip when it went up from the distribution box
When a breaker detects an abnormal surge, it “trips,” cutting off electricity to prevent potential damage. You can reset the breaker once the issue is resolved. It's working exactly as designed. It's shutting off power because something on that circuit isn't safe. The tripping is a warning signal, not a malfunction. But what's causing it? And more importantly, does it need an expensive fix, or is. The main circuit breaker is designed to protect the electrical system in a building or home from overload and potential fire hazards. This occurs when a hot wire touches a neutral wire or another hot wire. In this guide, we'll walk through these.
