Why does my breaker keep tripping?
Circuit overload
Repeated tripping is usually an overloaded circuit, a short in a device or cable, a ground fault, or a worn breaker. A breaker that trips with nothing plugged in points to a wiring fault and needs an electrician.
Safety first: Never replace a breaker with a higher-rated one. The breaker protects the wire, and oversizing it creates a fire risk.
Likely causes and what each costs to fix
| Cause | Likelihood | Fix | Cost |
|---|---|---|---|
| Circuit overload | Most common | Redistribute loads, or add a dedicated circuit. | $250–$900 |
| Faulty appliance or cord | Most common | Isolate by unplugging devices one at a time. | $0–$200 |
| Ground fault on a GFCI circuit | Common | Locate moisture intrusion or a damaged device. | $150–$500 |
| Worn or failed breaker | Common | Replace the breaker. | $150–$350 |
| Undersized or obsolete panel | Less common | Panel replacement or service upgrade. | $1800–$4500 |
What you can check yourself
- 1. Note which devices were running when it tripped
- 2. Unplug everything on the circuit and reset once
- 3. Test GFCI outlets on that circuit
- 4. Check for burning smells or discoloration at outlets
When to call a professional
- • The breaker trips with nothing connected
- • There is scorching, buzzing or a burning smell
- • The panel is a known-defective brand
- • Tripping is spreading to other circuits
