Why Does My Breaker Keep Tripping?
Causes & Solutions
Troubleshoot why your circuit breaker keeps tripping. Common causes from overloaded circuits to short circuits, and when to call a licensed LA electrician.
Why Your Circuit Breaker Keeps Tripping
A tripping circuit breaker is annoying, but it's also a safety feature protecting your home from electrical fires.
3 Main Causes of Tripping Breakers
Circuit Overload
Too many devices drawing power from one circuit — a 15A circuit running a vacuum, space heater, and computer simultaneously.
Short Circuit
A hot wire touches a neutral wire, causing a sudden surge. Burning smell or scorch marks. Requires immediate professional attention.
Ground Fault
A hot wire touches a grounded surface. GFCI breakers trip instantly. Common in kitchens, bathrooms, outdoor circuits.
How to Diagnose a Tripping Breaker
- Unplug everything on the affected circuit and reset the breaker.
- Plug devices in one by one. If it trips when plugging in a specific device, that device may have a short.
- Notice when it trips. Only when high-draw appliances run? Likely overload. Randomly? Probably a short or ground fault.
Safety warning: If a breaker trips repeatedly and won't reset, or you see burn marks, melted insulation, or smell burning — call a licensed electrician immediately.
