Breaker Keeps Tripping? Utah Electrical Diagnostic
Same breaker tripping repeatedly? Here's the diagnostic order Utah electricians use — most causes are fixable, but some signal a serious safety issue.
A breaker is doing its job when it trips — it stopped current to prevent a fire or shock. The question is what's CAUSING the trip. There are 5 distinct causes, each with a different fix.
Diagnostic
Most likely causes (in order)
Walk through the list top-to-bottom. The first cause matches roughly half of cases we see in Utah; if it doesn't fit your symptoms, move to the next.
Overloaded circuit
Too many devices on the same circuit. 15A circuit can handle ~1,800W; 20A can handle ~2,400W. Hair dryer + space heater on one bedroom circuit = trip.
Short circuit (hot to neutral or hot to ground)
Damaged wire insulation, rodent damage in the wall, or a faulty appliance with a short. Breaker trips immediately when reset. Smell of burning insulation possible.
Ground fault (GFCI)
Current leaking to ground (e.g., water in an outlet, frayed cord touching metal). GFCI breakers trip at much smaller currents (~5mA) than standard breakers.
Failing breaker
Breaker contacts wear out over decades. Trips below rated current. More common in older Federal Pacific or Zinsco panels (which have separate documented safety issues).
AFCI nuisance trip
Newer code-required AFCI breakers trip on arc faults. Sometimes oversensitive — vacuum cleaners, dimmers, and certain LED bulbs cause nuisance trips. Genuinely useful for fire prevention; sometimes annoying.
DIY first
Safe checks you can do today
Each step is labeled by safety level. Stop at any “Pro only” step — that's where the diagnostic crosses into work that needs gauges, multimeters, or live electrical access.
Reset the breaker ONCE
CautionPush fully OFF, then fully ON. Trips immediately again = short circuit. Trips after a few minutes of use = overload. Doesn't reset = breaker may be defective.
Identify what was running when it tripped
Safe DIYTwo high-draw devices? Overload. One specific device? Could be that device's fault — try plugging it into a different circuit and see if it trips that one too.
Unplug everything on the circuit
CautionReset breaker with nothing plugged in. If it stays on with nothing connected, it was an overload. If it trips with nothing connected, you have a wiring problem.
Stop here if breaker won't reset or trips with nothing connected
Pro onlyYou have a short, ground fault, or wiring problem behind the wall. Live electrical diagnostic — call.
Stop and call
When you should call us instead
- Breaker won't reset (stuck OFF or trips immediately)
- Breaker is hot to the touch — replace immediately
- Burning smell or scorch marks at panel — emergency, call same day
- Federal Pacific (FPE Stab-Lok) or Zinsco panel + tripping — replace panel, not just breaker

FAQ
Frequently asked questions
Is it safe to keep resetting a breaker that keeps tripping?
+
No. After 2–3 trips on the same fault, stop. Either you have a real problem the breaker is detecting (and continued resets risk fire) or the breaker is failing (and a failing breaker may not trip on the next fault). Either way, diagnostic time.
Can I just install a higher-amp breaker to stop it tripping?
+
No. Wire gauge dictates breaker size. A 14-AWG wire is rated for 15A; a 12-AWG wire is rated for 20A. Putting a 20A breaker on 14-AWG wire = overheated wire = fire. The breaker is the fuse for the wire, not the load.
