How to reset a tripped circuit breaker

A tripped circuit breaker is a safety feature that cuts power when a circuit is overloaded or a fault occurs. Resetting it is usually simple, but doing it safely matters. This guide explains the steps and when to stop.

What is happening

Breakers trip for two main reasons: an overload (too many devices drawing current) or a fault (short circuit or ground fault). Some breakers, especially GFCI or AFCI types, have a TEST/RESET button and may trip for safety reasons even without an overload.

Emergency warning

If you see sparks, smoke, flames, smell burning, or notice damaged wiring or a hot panel, do not touch the panel. Call your local emergency services immediately and then a licensed electrician. Never work on a panel that is wet or damaged.

Step by step

1. Turn off and unplug devices on the affected circuit. This reduces load and prevents surprises when power returns.
2. Locate the service panel and open the door. Use a flashlight if needed. Stand on a dry surface and keep one hand free.
3. Identify the tripped breaker. Its handle will be in the middle position (not fully ON or OFF). The label inside the panel can help.
4. Reset it: push the handle firmly to the OFF position, then push it fully to ON. You should feel a click.
5. Test the circuit by plugging in one device at a time. If it trips again, unplug everything and try once more. If it trips with nothing connected, stop.

If your breaker has a TEST/RESET button

Press RESET firmly. If it does not stay reset, the breaker or the circuit has a problem. Do not keep pressing it.

What NOT to do

• Do not reset a breaker repeatedly if it trips immediately. That indicates a fault.
• Do not use tools, tape, or force to hold a breaker in the ON position.
• Do not replace a breaker with a larger size or a different type unless a licensed electrician does it.
• Do not work inside the panel if you are unsure or if the panel looks damaged, rusty, or smells burnt.
• Do not ignore a breaker that feels hot or smells like burning plastic.

When to call a professional

Call a licensed electrician if: the breaker trips again right after resetting; multiple breakers trip; you see scorch marks or smell burning; the panel is warm; you have aluminum wiring; or you are not comfortable working near the panel. For any fire or smoke, call emergency services first.

How to prevent nuisance trips

• Distribute high-wattage appliances (heaters, hair dryers, microwaves) across different circuits.
• Use power strips with built-in overload protection and avoid daisy-chaining them.
• Have an electrician inspect your panel if trips are frequent.

Resetting a breaker is safe when done carefully. If it does not stay reset, stop and get professional help. This is general information, not a substitute for professional electrical advice.
