Fix a Circuit Breaker That Keeps Tripping

What is actually broken

Breakers trip for four reasons. Overload: the circuit is asked for more amps than it is rated for (a 15-amp circuit is about 1,800 watts, and one space heater is 1,500 of them). Short circuit: a hot wire touches a neutral or ground somewhere — instant trip, often with a pop or a smell. Ground or arc fault: modern GFCI/AFCI breakers trip on leakage or arcing signatures that older breakers ignored — sometimes a real hazard, sometimes a dying appliance leaking a trickle. And the breaker itself wears out after years of trips and starts letting go early. The tests below separate these in order, with nothing opened but outlet covers you can see.

The fix, step by step

1. 1 Reset it properly and note the timing

   A tripped breaker sits in a middle position — push it fully OFF first, then ON. Now note exactly when it trips: instantly, even with everything off, points to a short or ground fault in the wiring or a hard-faulted device. Tripping after minutes of use points to overload or heat. Tripping the moment one specific thing switches on names that thing.

   Tip: Write the timing down. 'Trips instantly' vs 'trips after the kettle and microwave run together' leads to completely different fixes.

2. 2 Empty the circuit completely

   Find everything on that circuit (flip lights and test outlets, or just work the rooms that went dark) and unplug — not just switch off — every device, especially heaters, hair dryers, microwaves, kettles, toasters, window ACs, and anything with a motor. Reset the breaker. If it trips instantly with everything unplugged, the fault is in the wiring, an outlet, or the breaker itself: stop here and call an electrician.

   Tip: Phone chargers and TVs draw almost nothing. The hunt is for heat-making and motor-driven loads — those are your amps.

3. 3 Add loads back one at a time

   With the breaker holding, plug things back in one at a time, running each for a minute. The device that trips it — or the combination that trips it — is your answer. A single device that trips the breaker the instant it starts, every time, has an internal fault: unplug it and retire or repair it. If only combinations trip it, that is plain overload: do the watt math (amps × 120 = watts; stay under 80% of the breaker's rating for steady loads) and move one big load to a different circuit permanently.

   Tip: Kitchens and bathrooms are the usual crime scenes: microwave + toaster oven, or hair dryer + space heater, each pair exceeds a 15 or 20-amp circuit on its own.

4. 4 Read the fault indicator if your breaker has one

   Many modern AFCI/GFCI breakers blink a code or have a test button and an indicator showing whether the last trip was overload, arc, or ground fault. Check the panel door label or the breaker maker's chart. A ground-fault trip with a bathroom, kitchen, garage, or outdoor device on the circuit points at that device or moisture in an outlet box. Repeated arc-fault trips on a circuit feeding an old vacuum or a worn extension cord are usually the device, not the house.

   Tip: Test GFCI outlets monthly with their own TEST button while you are at it — a GFCI that won't trip on test has failed silently and protects nothing.

5. 5 Decide: manage the load, replace the device, or call the electrician

   Overload solved by moving a load = done, free. One faulty appliance identified = done, replace the appliance. Everything else — instant trips on an empty circuit, trips at random with modest loads, a warm or buzzing breaker, any scorch or smell — is an electrician's diagnosis. A breaker that has tripped hundreds of times can itself be the fault, but proving and replacing it happens inside the panel. Not sure which bucket you are in?

   Tip: When you call, give the electrician your notes: when it trips, what was running, what you unplugged. Good notes turn a two-visit diagnosis into one.
