Circuit Breaker Keeps Tripping
A breaker trips repeatedly when you use certain appliances or outlets.
Circuit Breaker Keeps Tripping: A circuit breaker that keeps tripping is caused by an overloaded circuit, a short circuit, a ground fault, or a faulty breaker. Overloads are most common — too many devices on one circuit. If a breaker trips repeatedly, stop resetting it and call a licensed electrician. Diagnosis costs $100–$250, and repairs run $150–$500.
What Causes This?
Circuit Overload
Too many appliances or devices drawing power on the same circuit. Common in older Sacramento homes where kitchen, bathroom, or bedroom circuits weren't designed for modern loads like space heaters, hair dryers, and multiple electronics.
Short Circuit
A hot wire touches a neutral wire, creating a sudden surge of current. This can happen from damaged wiring, loose connections, or faulty appliances. Short circuits are a fire hazard — don't keep resetting the breaker.
Ground Fault
A hot wire contacts a ground wire or the grounded metal box, typically in wet areas like bathrooms, kitchens, or outdoor outlets. GFCI outlets should trip first, but a breaker-level trip indicates a bigger wiring issue.
Faulty or Worn Breaker
Circuit breakers wear out after years of use. A breaker that trips under normal loads or won't stay reset likely needs replacement. Common in panels older than 20 years.
Arc Fault
Damaged or deteriorated wiring creates electrical arcs — sparks jumping across gaps in the wire. Arc faults are a leading cause of electrical fires. AFCI breakers are designed to detect and stop them.
Can It Wait?
A repeatedly tripping breaker is a warning sign. Stop resetting it and unplug devices on that circuit. If you smell burning, see scorch marks, or hear buzzing from the panel, call an electrician immediately — these indicate a fire risk.
What Does It Cost?
| Item | Cost Range |
|---|---|
| Diagnostic Visit | $100–$250 |
| Breaker Replacement | $150–$350 |
| Circuit Rewiring | $300–$800 |
| Adding a New Dedicated Circuit | $200–$500 |
| Panel Upgrade (if needed) | $1,800–$4,500 |
Repair vs. Replace
Repair
Replace the breaker if: it's a single faulty breaker and the rest of the panel is in good condition. Add a dedicated circuit if the issue is overload on a single circuit.
Replace
Upgrade the panel if: breakers trip frequently across multiple circuits, the panel is a Federal Pacific or Zinsco brand (known fire hazards), or the panel is under 100 amps and can't support your home's electrical needs.
Rule of thumb: If your home has a 60- or 100-amp panel and you're adding EV chargers, heat pumps, or major appliances, a 200-amp panel upgrade ($1,800–$4,500) is the right long-term solution.
When to Call a Contractor
- ✓A breaker trips more than twice in a day under normal use
- ✓You smell burning or see scorch marks around the panel or outlets
- ✓The breaker won't stay reset or feels hot to the touch
- ✓Multiple breakers trip simultaneously
- ✓You have a Federal Pacific, Zinsco, or Pushmatic panel

Circuit Breaker Keeps Tripping — FAQ
Why does my breaker keep tripping?
The most common cause is circuit overload — too many devices on one circuit. In Sacramento-area homes built before 1990, kitchens and bedrooms often share circuits that can't handle modern appliance loads. Other causes include short circuits, ground faults, and worn-out breakers.
Is a tripping breaker dangerous?
The breaker itself is doing its job — protecting your home from electrical fires. But the underlying cause may be dangerous. Repeated tripping from short circuits or arc faults indicates wiring problems that can start fires. Have an electrician diagnose the cause rather than continuing to reset it.
How much does it cost to fix a tripping breaker?
A diagnostic visit costs $100–$250. A simple breaker replacement runs $150–$350. If the circuit needs rewiring or a dedicated circuit added, expect $200–$800. If the whole panel needs upgrading, that's $1,800–$4,500 for a 200-amp upgrade.
