Why Does My Circuit Breaker Keep Tripping?
A circuit breaker keeps tripping for one of four reasons: too many devices on the circuit (overload), a short circuit, a ground fault, or a worn-out breaker. If it trips again right after you reset it, or you smell burning, stop resetting it and call a licensed electrician.
1. Circuit overload
Space heaters, hair dryers, air fryers and window AC units draw a lot of current. If the breaker trips when you run several at once, move a load to another circuit or have a dedicated circuit added.
2. Short circuit
A hot wire touching a neutral causes a large surge of current and an instant trip. Look for scorch marks or a burning smell. This needs an electrician.
3. Ground fault
Current leaking to ground, often from moisture in outdoor outlets or a failing appliance, trips GFCI devices. Unplug items one at a time to find the culprit.
4. Arc fault
AFCI breakers trip when they detect arcing from damaged cords, loose connections or nails through wires.
5. A failing breaker or panel
Breakers wear out. Some older panels, such as Federal Pacific and Zinsco, are known for problems. See circuit breaker repair and panel upgrades.
What you can safely check
- Unplug everything on the circuit and reset the breaker.
- Plug items back in one at a time.
- If it trips with nothing plugged in, or trips instantly, stop and call 657-201-1586.
