What a tripping breaker means
It is doing its job — protecting the wiring from overload, a short circuit, or (for AFCI/GFCI) an arc or ground fault.
Step 1 — Unplug everything on the circuit
Reset the breaker. If it holds, plug devices back in one at a time. The one that trips it is the culprit.
Step 2 — Check for visible damage
Look at outlets and switches on that circuit for scorch marks, melted plastic, or warmth. If you see any, stop and call a licensed electrician.
Step 3 — GFCI / AFCI specifics
These trip on ground faults or arcing — usually a moisture issue or a damaged cord.
When to call a pro
- Breaker trips with nothing plugged in
- You smell burning plastic at the panel
- Lights dim or flicker on multiple circuits
