Breaker Keeps Tripping
Why your breaker keeps tripping, how to tell if it's overload / short circuit / ground fault, and when to call a licensed electrician.
A breaker that trips repeatedly is doing its job — it's protecting your home from a fault. The question is whether the fault is an overload (too much load on the circuit), a short circuit (hot touching neutral or ground), a ground fault (leakage to ground), an arc fault (loose connection sparking), or a bad breaker itself. Here's how to tell — and when to stop resetting and call a licensed electrician.
Key details
- Overload: too many devices on one circuit
- Short circuit: hot wire touching neutral or ground
- Ground fault: leakage to ground (typical near water)
- Arc fault: loose connection causing arcing
- Bad breaker: worn or heat-damaged trip mechanism
- Never keep resetting — it's a fire risk
First, isolate the load
Unplug everything on that circuit. Reset the breaker. If it holds, plug items back in one at a time — the one that trips it is either faulty or the last straw on an overloaded circuit. If the breaker trips instantly with nothing plugged in, you have a hardwired issue: bad breaker, damaged wire, or a shorted device.
When it's an AFCI or GFCI trip
Arc-fault breakers protect bedroom circuits and trip on any arcing (loose neutral in a receptacle, damaged wire, some noisy motors). GFCI-protected outlets trip on any leak to ground. Both are legitimate safety devices — repeated tripping means something on the circuit is actually wrong.
When to call
Any trip that repeats within minutes, any burning smell, any warm-to-touch breaker or panel, any trip that happens with nothing plugged in, or any tripping breaker in a Federal Pacific, Zinsco, or Challenger panel — these are all reasons to stop resetting and call a licensed electrician.
