BREAKER REPAIR
Breaker that trips immediately, will not reset, or feels hot? A licensed electrician diagnoses the failure mode and quotes the fix in writing.
Keil Electric diagnoses and repairs failed circuit breakers across San Diego County and the Austin metro. We test the breaker under load, distinguish a bad breaker from an overloaded circuit or a downstream fault, and replace the breaker with a manufacturer-spec part. Licensed work, written warranty.
Same scope on either side. Pick the shop that covers your area and we will route you to the right crew.
The breaker is doing its job by tripping. The question is why. We test the breaker mechanism itself, then test the downstream circuit for shorts, ground faults, overloads, and arc faults. Sometimes the breaker is bad. Sometimes the circuit is overloaded. Sometimes a single device on the circuit has failed and is shorting.
Breakers fail mechanically. The internal trip mechanism gets sluggish from heat cycling, the contacts pit from years of arcing, or the case warps. We replace the breaker with a manufacturer-spec part (the panel brand matters, since cross-brand swapping voids the panel listing) and re-test.
If the breaker tests good, we move downstream. We isolate each device on the circuit and check for shorts, find loose connections at outlets and switches, and look for damaged Romex behind drywall where a nail or screw has hit the cable. The fix is the underlying issue, not a breaker swap.
AFCI breakers (arc fault) and GFCI breakers (ground fault) trip on different conditions than standard breakers. Nuisance trips on these are common with certain loads (large motors, switching power supplies, older lighting). We diagnose the actual fault vs the nuisance and recommend the right path.
You describe what is on the circuit, what triggers the trip, and how often. That narrows the diagnostic before we arrive.
We test the breaker on the bench, then isolate the circuit to find the fault location.
We write what is wrong, what we are replacing, and the cost. You sign before we work.
We make the repair, restore the circuit, and verify the breaker holds under the original load condition that triggered the trip.
Not every job requires a permit. When the local AHJ requires one, we pull it, schedule the inspection, and stay with the job until it passes. No paperwork on you.
Written warranty: 5-year on outlets, fixtures, and EV chargers; 10-year on wire and breakers; lifetime on panelboxes and surge protection. Parts and labor. Transfers with the home.
A breaker that trips immediately on reset is doing its job. Continuing to reset it can ignite an overloaded conductor or a faulted device. Stop resetting it. We diagnose what is causing the trip and address the underlying issue, not just swap the breaker.
Real work from our San Diego and Austin shops. Same standards, same warranty, every job.
For circuit breaker repair, here's the honest comparison. We'd tell you the same thing if we weren't trying to win the job.
Most circuit breaker repair calls fall into one of three patterns: a single component failed and the symptom is obvious, a slowly degrading connection finally tripped or stopped working, or a previous repair (yours, a handyman, or a prior contractor) was never quite correct and the underlying issue surfaced again. If the symptom involves smoke, sparks, burning smell, or a panel that is hot to the touch, do not wait. Call the local shop. Active hazards get same-day dispatch when capacity allows. Routine repairs go on the next-available slot, usually inside the same week.
The first 20 to 30 minutes is observation and diagnosis: walk the symptom with you, check the panel for related issues, trace the affected circuit, identify the actual root cause rather than the easy answer. Most circuit breaker repair issues sit somewhere other than where the symptom shows up (lights flicker because of a loose connection at the panel, an outlet stops working because of a backstab failure on the next outlet downstream). The diagnostic is the actual job, the price reflects that. We write the scope after the diagnosis, not before.
Circuit breakers are designed to fail safely. When they trip, they are protecting the wiring and equipment downstream from a fault condition. The point is not to make the trip stop, it is to find the underlying issue. We get circuit breaker calls from homeowners and businesses across both shops, and the failure modes cluster into a few clear categories.
Overload: more amps drawn than the breaker is rated for. Short circuit: hot conductor touching a neutral or ground conductor, drawing massive instantaneous current. Ground fault: hot conductor touching a metal surface that is bonded to ground. Arc fault: an arcing condition somewhere in the circuit that an AFCI breaker is designed to detect. Each one needs a different diagnostic path.
An immediate trip on reset, with no load on the circuit, says short or hard ground fault. A trip after a few seconds under load says overload, marginal short, or thermal trip from a loose connection somewhere on the circuit. Random trips at no obvious load condition often mean a failing AFCI breaker reacting to switching power supply noise or a loose connection generating arc signature.
We use the manufacturer-spec breaker for the panel. Square D QO panels get Square D QO breakers. Eaton CH panels get Eaton CH breakers. Cross-brand breakers fit physically but are not listed for the panel and create a fire and code-compliance issue. We document the repair, including the breaker model installed, in the customer file.
There are four common causes: an overloaded circuit (too many devices), a short circuit (hot wire touching neutral or ground), a ground fault, or a failed breaker. The breaker is telling you something is wrong, not malfunctioning. We diagnose which condition is causing the trip and fix the actual problem.
Replacing a breaker without diagnosing the trip cause leaves the underlying problem in place. If the circuit is overloaded or has a short, the new breaker will trip too. We test the circuit first, then replace the breaker only when the breaker is the actual failure.
A hot breaker means high resistance, which usually means a loose connection at the lug or a worn breaker contact. That heat can scorch the bus bar and damage the panel. Stop using the affected circuit and have it diagnosed.
No. Each panel is listed for specific breaker brands. Cross-brand swapping voids the panel UL listing and creates a fire risk. We use manufacturer-spec breakers for the panel brand on every repair.
A standard breaker replacement is a small repair. AFCI and GFCI breakers cost more (the breaker itself is more expensive). We quote in writing after the diagnostic so the cost is fixed before work starts.
Tell us what is on the circuit and what triggers the trip. A licensed electrician arrives, diagnoses, and writes the repair scope before any work begins.
