AFCI INSTALL
AFCI protection where the code requires it: bedrooms, living areas, dining rooms, hallways. Manufacturer-spec breakers, licensed install.
Keil Electric installs AFCI breakers across San Diego County and the Austin metro to bring older homes up to current NEC requirements. AFCI protection is required by code in bedrooms, living areas, dining rooms, hallways, and most of the rest of a dwelling unit. We swap standard breakers for AFCI on the affected circuits.
Same scope on either side. Pick the shop that covers your area and we will route you to the right crew.
An arc fault is a low-current electrical arc, often inside a wall, that does not draw enough current to trip a standard breaker but generates enough heat to start a fire. AFCI breakers monitor the waveform on the circuit and trip when they see the signature of an arc. They are required by NEC because they catch a failure mode that standard breakers miss.
NEC 210.12 requires AFCI on most 120V branch circuits in dwelling units: bedrooms, living rooms, family rooms, dining rooms, kitchens, hallways, closets, laundry, and similar areas. The list expanded over multiple code cycles. We map the existing panel against current code and identify which circuits need AFCI protection added.
AFCI breakers can sometimes nuisance-trip on older wiring with multi-wire branch circuits, shared neutrals, or aged Romex with deteriorating insulation. We diagnose the cause rather than work around it. Sometimes the fix is correcting the wiring, sometimes it is a different breaker manufacturer with better immunity to the specific load type.
AFCI protects against arc faults. GFCI protects against ground faults (current going through a person to ground). Some breakers do both (dual-function). The right choice depends on the circuit and the room. We pick per circuit, not by reflex.
We inspect the existing panel, identify the brand, and map circuits against current code AFCI requirements.
We list which circuits get AFCI breakers, the breaker model, and the install cost. You sign before we proceed.
Power down, swap the standard breakers for AFCI breakers, restore power, and verify each circuit holds under load.
We trip each new AFCI breaker via the test button to confirm the AFCI mechanism works, and document the install.
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.
AFCI breakers detect arcing in the wiring and trip before a fire develops. Nuisance trips are sometimes caused by older lighting or switching power supplies, and we troubleshoot those rather than reverting to a standard breaker.
Real work from our San Diego and Austin shops. Same standards, same warranty, every job.
For AFCI breaker installation, here's the honest comparison. We'd tell you the same thing if we weren't trying to win the job.
Most AFCI breaker installation calls start when the homeowner is planning ahead: a renovation, an addition, an EV charger, a generator, a panel upgrade, or any project where the existing electrical needs to be sized correctly for the new load. The earlier we walk the property, the cleaner the project sequencing. Bringing us in before the drywall closes saves rework. Bringing us in before the contract is signed with the GC saves scope confusion. We are happy to walk a property at the planning stage even if the install is still months out.
A walk of the property with attention to the panel (age, capacity, available breaker space), conduit accessibility, attic / crawlspace conditions, and the load picture (current loads + planned future loads). For installs that touch the service drop, we factor utility coordination from the start. The estimate we leave with is fixed for the scope as walked. Change orders only happen for genuinely new findings during the work, you hear about them before we proceed.
AFCI breaker installation is one of the most under-requested fire-prevention upgrades in residential electrical work. The NEC has required AFCI in dwelling units since 1999 and the requirement keeps expanding. Most homes built before 2002 have zero AFCI protection. Adding it is a panel-level upgrade that catches a failure mode the original wiring was never designed to detect.
Imagine a Romex cable inside a wall where a screw has nicked the insulation. The hot conductor is barely touching the ground conductor, drawing maybe 2 amps through the partial connection. A standard 15A breaker sees 2 amps and does nothing. The 2 amps generate localized heat at the nick. Over months or years, the heat carbonizes the insulation, the carbonized path conducts more, and you have a slow-motion fire start inside the wall. AFCI breakers see the arc signature on the waveform and trip before that develops.
Panels manufactured before AFCI requirements existed were not designed for the larger AFCI breaker form factor or the test-button mechanism. We confirm AFCI compatibility for the panel brand and series before quoting. When the panel does not support AFCI, the upgrade path is the panel itself, not a one-off breaker swap.
New construction and most renovations are required to. For an existing home with a working panel, the code usually does not retroactively require AFCI on circuits that were code-compliant when installed. Many homeowners add AFCI voluntarily because of the fire-prevention benefit.
AFCI breakers are made by every major panel manufacturer (Square D, Eaton, GE, Siemens). The panel has to support AFCI, which means most panels manufactured after the early 2000s. Older panels sometimes need a different solution. We confirm panel compatibility on the site visit.
Common causes are switching power supplies in older electronics, certain LED dimmers, large motor loads, and shared neutrals on multi-wire branch circuits. The fix is usually to identify the specific load that triggers the trip, then either upgrade the device or change the AFCI breaker manufacturer.
Cost depends on the number of circuits and the panel brand. AFCI breakers are several times the cost of standard breakers. We quote in writing after panel inspection so the number is fixed before we start.
No. They serve different purposes. AFCI catches arc faults, GFCI catches ground faults to people. Some circuits in kitchens and laundry need both, which is what dual-function (combination AFCI/GFCI) breakers do. We pick the right type per circuit.
A licensed licensed electrician walks the panel, identifies the circuits that need AFCI under current code, and quotes the swap in writing. Manufacturer-spec breakers, fixed-price install.
