Panel Upgrade & Replacement in El Cerrito, CA | AC3 LLC (AC3 Electric)

El Cerrito homeowners often add EV chargers, heat pumps, and induction ranges on services that were sized decades ago. When the panel is also a Zinsco, Federal Pacific, or Challenger — or insurance has already flagged it — a permitted upgrade is the clean path forward. AC3 LLC (AC3 Electric) does that work locally.

Call 510-224-5795.

Panel work tailored to El Cerrito

We focus on safe, code-compliant replacements and capacity upgrades:

  • Insurance-driven replacement of Zinsco, FPE Stab-Lok, and Challenger panels
  • 200 amp Square D / Homeline solar-ready service upgrades
  • Meter/main and indoor panel work with labeling and inspection
  • PG&E coordination and Greenbook-compliant service equipment when the utility is involved
  • City of El Cerrito permit and inspection included in the job process

For planned jobs, expect standard city permit timing — not an emergency rush window. If you have a true emergency (failed main, burned bus bar, no power), say so when you call so we can prioritize correctly. Permit fees are set once final scope is confirmed; they stay excluded from quoted totals until then.

Capacity for the loads El Cerrito homes are adding

Hillside and flats homes alike are pushing past 100A once heat pumps, Level 2 charging, and kitchen electrification stack up. A load calculation tells us whether a full 200 amp upgrade is needed or whether options like a SPAN smart panel make sense for load management. When a service upgrade is the right answer, we install solar-ready Square D Homeline equipment and walk the job through PG&E and the city.

If you’re planning a heat pump, our heat pump electrical / rebates page covers the circuit, disconnect, and panel-capacity side we handle alongside your HVAC installer.
