Why does my circuit breaker keep tripping?
A breaker that keeps tripping is protecting you from one of four things: an overloaded circuit (too many devices), a short circuit (bare wires touching), a ground fault (current finding an unintended path), or a failing breaker that trips under normal load. The fix ranges from free (unplug some devices) to a $150–$400 electrician call for a new breaker.
Most recurring trips are overloads — you've added too much draw to one circuit. But a breaker that trips the moment you reset it, or one that trips under normal loads it handled for years, points to a wiring or breaker failure that needs same-day attention.
4 reasons a breaker keeps tripping
Overloaded circuit
$0 (redistribute) or $200–$500 (new circuit)How to tellBreaker trips when multiple high-draw devices (hair dryer, space heater, microwave) run on the same circuit; no trips when you use fewer devices
The fixMove devices to different circuits; for recurring kitchen or bathroom issues, add a dedicated circuit
Short circuit
$0–$60 (replace device) or $150–$400 (outlet/wiring repair)How to tellBreaker trips immediately on reset with a loud pop or burning smell; often caused by a frayed cord, damaged outlet, or faulty appliance
The fixUnplug everything on the circuit; plug devices back in one at a time to find the culprit. If it's wiring, call an electrician
Ground fault
$150–$300How to tellBreaker trips near water — in kitchen, bathroom, garage, or outdoors; GFCI outlet won't reset
The fixGFCI outlet replacement is often the fix; if trips continue, there's a downstream wiring issue
AFCI nuisance tripping
$150–$300 diagnostic + $40–$100 per replacement breakerHow to tellNewer home or recently updated panel; breaker trips randomly with normal loads, especially with older appliances or power strips with surge protection
The fixAFCI breakers can be triggered by electronic noise from certain appliances; an electrician can test for true AFCI faults vs nuisance trips
Failing breaker
$150–$400How to tellCircuit handled the same loads for years; now trips under normal conditions; breaker feels warm or won't stay reset
The fixReplace the breaker — licensed electrician job; don't attempt yourself
Try this first (before you pay anyone)
- Unplug everything on the tripping circuit, reset the breaker, then plug devices back in one at a time. If it trips immediately with nothing plugged in, the problem is the wiring — stop and call an electrician.
- Check if it's a GFCI breaker — these have a test/reset button on the breaker face itself. Press the reset button firmly; sometimes GFCI breakers just need a manual reset.
- Look for the obvious: a visibly frayed cord, a burning smell from an outlet, or a device that was recently added to the circuit. Replace or remove that device first.
- For kitchen and bathroom trips: those should be on GFCI-protected circuits. If the GFCI outlet won't reset, the outlet itself has likely failed — a $15 part, easy DIY or $150–$200 with an electrician.
Unlock the hiring checklist
Use this before you call an electrician, so you know what to ask and what to avoid.
Call a pro when…
- Breaker trips the moment you reset it with nothing plugged in — this is a wiring fault, not an overload
- You smell burning plastic or see scorch marks around an outlet or the panel
- A breaker feels hot, warm, or has visible discoloration — this is a fire risk
- The same breaker keeps tripping after you've removed the obvious overload sources — a failing breaker or hidden wiring fault needs diagnosis
Repair or replace?
Individual breakers cost $5–$60 for the part; electrician labor to swap one runs $150–$400 including panel access time. That's almost always worth it. The question of replacing the whole panel only comes up if you have a documented hazardous brand (Federal Pacific, Zinsco) or your panel is genuinely full with no room for the circuits you need. One bad breaker doesn't mean a bad panel.

Related questions
Is a tripping breaker dangerous?
The breaker tripping is actually the safety system working — it's protecting your wiring from overheating. The danger is when a breaker should trip but doesn't (failing to protect), or when you repeatedly reset a breaker without finding the cause. If a breaker keeps tripping, treat it as a problem to solve, not a nuisance to reset.
Why does my breaker trip only at night?
Nighttime trips are often from HVAC systems — heat or AC running without competition from daytime loads can push a circuit to its limit. Also check if any appliances run on timers or charge overnight (phone chargers, EV chargers, dishwasher on delay) that you haven't accounted for.
Can I replace a breaker myself?
Technically it's DIY-able, but the panel interior has live busbars that carry lethal voltage even with the main breaker off. Most homeowners should hire an electrician. If you're confident with electrical work and know to never touch the two wires feeding the main breaker, it's a 20-minute job. Permit is typically not required for a single breaker swap.
What's the difference between a short circuit and a ground fault?
A short circuit is when a hot wire touches a neutral wire directly, creating a low-resistance path and a surge of current. A ground fault is when a hot wire touches a grounded surface (a metal box, a wet floor, your hand) — same dangerous surge, different path. GFCI protection catches ground faults in milliseconds; a standard breaker catches short circuits.
