How do I reset a tripped circuit breaker?

Resetting a tripped circuit breaker is straightforward, but first identify why it tripped to prevent it from happening again.

A tripped breaker is a safety feature working correctly - it detected an overload, short circuit, or ground fault and cut power to protect your home from fire or electrocution. Before resetting, unplug devices from the affected circuit and look for obvious problems like damaged cords or overloaded outlets.

To reset the breaker, go to your electrical panel and look for a breaker that's in the middle position (not fully ON or OFF) or one that looks different from the others. Some breakers have a red or orange indicator when tripped. Firmly push the breaker handle all the way to the OFF position first, then push it back to the ON position. You should hear a click when it engages properly.

If the breaker trips immediately again, don't keep resetting it. This indicates a serious problem like a short circuit or ground fault that needs professional attention. Repeatedly resetting a breaker that keeps tripping can cause overheating and fire risk.

Common causes of tripped breakers include too many devices on one circuit (especially space heaters, hair dryers, or microwaves), damaged extension cords, faulty appliances, or moisture in outlets. In Ottawa's older homes, 15-amp circuits are common and can easily overload with modern electrical demands.

When to call an electrician: If breakers trip frequently, if you smell burning, if outlets feel warm, or if you're uncomfortable working at the panel. Under the Ontario Electrical Safety Code, homeowners can reset breakers, but any repairs to the panel or wiring require a licensed electrician.

For persistent electrical issues or if you're dealing with an older panel that needs upgrading, Electrical Ottawa provides free consultations to assess your electrical system's safety and capacity.
