What should I do if a breaker keeps tripping?

A breaker that trips repeatedly is doing its job. Unplug loads on that circuit and reset once. If it trips again with nothing connected, stop and call an electrician.

Overload — too much load on one circuit — is the benign explanation. A short circuit or ground fault is not, and repeated resetting of a faulting circuit is a fire risk.

Never replace a breaker with a higher-rated one to stop tripping. The breaker protects the wiring, and oversizing it removes that protection.

What to check first

  • What is plugged into the circuit, and whether one appliance causes the trip
  • Whether the trip is a standard breaker, a GFCI, or an AFCI device
  • Signs of damage: warm faceplates, scorch marks, buzzing, burning smell
  • Whether the circuit is shared with a high-draw appliance

When to call a professional

  • The breaker trips with all loads disconnected
  • There is any heat, arcing, buzzing or burning smell
  • The panel shows corrosion, moisture or damaged components
