GFCI and AFCI breakers trip on leakage current or arcing, not just overload. A GFCI/AFCI breaker tripping under load or at random is doing its job — the cause is a leakage or arc path to find, not too much load.

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.
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.
