My breaker keeps tripping and won't reset — is it dangerous?
A breaker that trips again immediately after one reset is telling you there's a real fault on that circuit — an overload, a short, or a failing device — and continuing to force it is how wires overheat inside walls. One reset is reasonable; repeated resets are not.
- Unplug everything on the affected circuit, then try one firm reset: push the handle fully to OFF, then to ON.
- If it holds, plug things back in one at a time — the item that trips it again is your suspect.
- If it trips instantly with nothing plugged in, or the breaker or panel feels warm, stop. Leave the breaker off and have a licensed electrician trace the fault.
- Never swap in a bigger breaker to stop the tripping — the breaker size must match the wire it protects.
