SAFE NEXT CHECKLeave it off and stop resetting it. With nothing plugged in, an instant trip means a fault in the wiring or a hardwired device — finding it means opening the circuit, which is an electrician's job.
Where to stop. Resetting a breaker once is homeowner-safe. A breaker that keeps tripping is protecting against a real fault or overload — do not repeatedly reset it, and never tape, wedge, or oversize it. Opening the panel and any wiring repair is a licensed electrician's job. This is general information, not a quote and not a substitute for a licensed electrician.
Try the safe next check above. If it doesn't resolve it, or would mean working on wiring or a panel, stop and call a licensed electrician — don't replace parts on a guess. Open the full tool to change any answer for your exact situation, or try a related check below.
Electrical Fault Check provides general diagnostic information only. It is not professional advice, not a quote, and not a substitute for a licensed electrician. Do not work on live wiring. If you see smoke, sparks, burning smell, heat, shock, water exposure, or repeated tripping, stop using the circuit and contact a licensed electrician or emergency services as appropriate.
