Breaker Keeps Tripping? How to Reset It and Find the Cause
How to safely reset a tripped breaker, the four reasons breakers trip, and the warning signs that mean you need an electrician instead of another reset.
Quick Answer
A breaker trips to protect the wiring. Unplug what was running, push the breaker handle firmly to OFF, then back to ON. If it trips again right away, or keeps tripping, there is a short, ground fault or failing breaker that needs an electrician.
Key Guide Highlights
How to Reset a Tripped Breaker
1. Turn off or unplug the lights and devices on the circuit that lost power.
2. Open the panel and find the tripped breaker. Its handle sits in the middle, between ON and OFF, or shows a red or orange flag.
3. Push the handle firmly all the way to OFF. You should feel it click.
4. Push it back to ON.
5. Plug things back in one at a time to see if one device causes the trip.
If your panel feels hot, smells like burning, or shows scorch marks, do not reset anything. Call an electrician.
The 4 Reasons Breakers Trip
1. Circuit Overload
The most common cause. Too much is running on one circuit at once, like a space heater and a vacuum, or a microwave and a toaster oven. The breaker trips after a few seconds or minutes, and resets fine once you unplug something.
2. Short Circuit
A hot wire touches a neutral wire, usually from a damaged cord, a loose connection or a failing outlet. The breaker trips instantly, sometimes with a pop or a spark. Do not keep resetting it.
3. Ground Fault
Current leaks to ground, often through water in an outdoor outlet, a wet bathroom fixture or a damaged appliance. GFCI breakers and outlets trip on very small leaks to protect people from shock.
4. Arc Fault or a Worn Breaker
AFCI breakers trip when they detect sparking in damaged wires or loose connections. Breakers also wear out with age and can start tripping below their rating.
Which One Is It?
The timing of the trip tells you a lot:
| What You Notice | Likely Cause | What to Do |
|---|---|---|
| Trips after running a while | Overload | Move a heavy appliance to another circuit |
| Trips the instant you reset it | Short circuit | Leave it off and call an electrician |
| Trips when it rains | Ground fault outdoors | Check outdoor outlets and covers |
| Trips with one appliance | That appliance | Try it on another circuit |
When to Call an Electrician
A breaker that trips once after an overload is doing its job. Call us if:
- It trips again immediately after you reset it
- It trips repeatedly with nothing unusual plugged in
- You see scorch marks, smell burning or hear buzzing at the panel or an outlet
- You are constantly juggling appliances to avoid trips, which means you need more circuits
