BREAKER REPLACEMENT
Manufacturer-spec breaker replacement on Square D, Eaton, GE, Siemens, and other listed panels. Single-pole through 200A main, in writing.
Keil Electric replaces failed circuit breakers across San Diego County and the Austin metro. We use manufacturer-spec breakers (Square D QO, Eaton CH, GE THQ, Siemens QP) matched to the panel listing, swap on a single visit when the breaker is the verified failure, and document the replacement.
Same scope on either side. Pick the shop that covers your area and we will route you to the right crew.
Each panel is UL-listed for specific breaker brands and series. The bus stab geometry, contact metallurgy, and trip mechanism are designed together. Putting a different brand breaker into a panel might fit physically but is not listed and creates a fire risk plus a code violation. We use manufacturer-spec breakers on every replacement.
Standard thermal-magnetic breakers are the cheapest and used on general-purpose circuits. AFCI breakers are required by code in bedrooms, living areas, and other locations. GFCI breakers are required in kitchens, baths, garages, outdoor circuits, and within six feet of water. We replace with the right type for the location, not just whatever was in there before.
Replacing the main breaker requires de-energizing the panel by either pulling the meter or scheduling a utility cut. We coordinate the disconnect, replace the main breaker, and re-energize. The work is bigger than a branch breaker swap but follows the same logic: verify the failure, replace with manufacturer-spec, re-test.
If the panel itself is FPE Stab-Lok, Zinsco, or another recalled obsolete design, breaker replacement does not solve the safety issue. The breakers in those panels do not trip reliably, period. We say so in writing and quote the panel upgrade instead.
We test the breaker under load to confirm it is the failure point and not a downstream fault.
Manufacturer-spec breaker matched to the panel brand and current generation.
Power down, swap the breaker, torque the lugs to spec, restore power, and verify under the original load condition.
Replacement breaker model goes in the customer file along with the panel directory update.
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.
Always confirm the breaker is the failure point before swapping. A new breaker on a faulted circuit will trip too. We diagnose first, replace second.
Real work from our San Diego and Austin shops. Same standards, same warranty, every job.
For circuit breaker replacement, here's the honest comparison. We'd tell you the same thing if we weren't trying to win the job.
Most circuit breaker replacement 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 replacement 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.
Replacing a circuit breaker is a small repair that has to be done correctly. The panel listing, the breaker brand, the torque on the lugs, the diagnostic that confirms the breaker is actually the failure, all of it matters. We do this work weekly across both shops and the consistent pattern is that customers call us after another contractor swapped a breaker and the trip kept happening because the underlying fault was never addressed.
Before we replace anything, we verify the breaker is bad. A breaker that trips immediately under no load is testable on the bench. A breaker that trips under specific load conditions tells us either the breaker is marginal or the circuit is overloaded. The diagnostic step gets skipped in commodity electrical work and that is why repeat trips happen after a “fix.”
Square D QO, Square D Homeline, Eaton CH, Eaton BR, GE THQ, Siemens QP. Each one is a different physical interface and a different listing. We carry the common ones in the truck for both shops because mismatch is the leading cause of a re-call on this work.
Cost depends on the breaker type. A standard 15A or 20A breaker is the cheapest. AFCI and GFCI breakers cost more because the parts cost more. Main breakers run higher because of the panel disconnect required. We quote in writing.
In most jurisdictions a homeowner can legally do this work. We do not recommend it. The panel is energized at the service-entrance lugs even when the main breaker is off, and a slip with a tool there is potentially fatal. A licensed electrician brings the right test gear and the safety procedure.
We test the breaker on the bench under simulated load. If it trips immediately at low current, it is failed. If it holds at rated current, the breaker is fine and we move downstream to find the actual fault.
Yes. The breaker amperage is sized to the wire gauge on the circuit. Putting in a higher-amp breaker would let the wire overheat without tripping, which is a fire risk. We replace at the same amperage unless the wire is being upgraded too.
A standard branch breaker replacement is usually under an hour, including the test and re-verification. Main breaker replacements that require a utility cut take longer because of the coordination, usually three to four hours total.
A licensed electrician verifies the breaker is the actual failure, replaces it with the manufacturer-spec part, and re-tests under load. Fixed-price quote, written warranty.
