Replacing a circuit breaker means working bare-handed millimeters away from the live "bus bar" inside your electrical panel, which carries enough raw voltage from PG&E to be lethal. This is never a DIY project. When Dollens Electric replaces or repairs a breaker, we follow strict safety protocols:

1. Diagnostic Load Testing: We do not blindly swap out breakers. We use a professional multimeter to measure the actual electrical draw on the circuit. This tells us definitively if the breaker itself is faulty, or if the circuit is genuinely overloaded by your appliances and requires a dedicated line.

2. Live Panel Safety & Power Isolation: We safely remove the panel's deadfront cover and, whenever possible, shut off the main power to isolate the panel. Our veteran electricians use specialized insulated tools and personal protective equipment (PPE) to safely extract the defective switch.

3. Bus Bar Inspection: Before installing a new breaker, we rigorously inspect the metal bus bar it snaps onto. If the old breaker was arcing, it may have pitted or burned the metal bus bar, which would require a larger panel repair to ensure a safe, flush connection.

4. Exact Brand & Amperage Matching: You cannot put a 20-amp breaker on a wire rated for 15 amps, and you cannot mix and match breaker brands (like shoving a Square D breaker into a Siemens panel). Doing so violates the National Electrical Code (NEC) and creates a fire hazard. We install the exact, manufacturer-approved replacement.

5. AFCI/GFCI Code Upgrades: If we are replacing a standard breaker that services a bedroom, kitchen, or wet area, modern California building codes often require us to upgrade it to a dual-function AFCI (Arc-Fault) or GFCI (Ground-Fault) breaker to provide your home with advanced fire and shock protection.
