Electrical · Sourced answer

Why does my circuit breaker keep tripping repeatedly?

Consumers ask whether the cause is an overloaded circuit, a short circuit, a ground fault, or a faulty breaker.

Ask about your own electrical problem

The answer

Breakers trip to prevent wires from overheating and causing fires. Causes:

  1. Overloaded circuit (connected devices exceed 15A/20A breaker rating)
  2. Short circuit (hot wire touches neutral/hot, causing current spike)
  3. Ground fault (hot wire contacts ground path)
  4. Arc fault (damaged cords or loose terminations detected by AFCI).
