San Pablo Electrical Panel Upgrade | AC3 LLC (AC3 Electric)

In San Pablo, a lot of panel calls start the same way: an insurance inspection flags the old breaker box, or the homeowner wants an EV charger / heat pump and the existing 60A or 100A service won’t support it. AC3 LLC (AC3 Electric) replaces those panels and upgrades service when needed — with the city permit and PG&E steps built into the job.

What San Pablo panel upgrades usually involve

  • Replacing Zinsco, Federal Pacific (FPE), and Challenger panels insurers commonly reject
  • Installing a new 200 amp Square D Homeline solar-ready meter/main when capacity is short
  • Indoor panel replacements with every circuit labeled
  • Working to PG&E Greenbook requirements on service upgrades and coordinating disconnect/reconnect
  • Pulling the City of San Pablo (or applicable) permit and scheduling inspection as part of the project

Planned work uses standard municipal permit timing. We do not treat routine upgrades like emergency panel failures; if you have a burned-up bus bar or an urgent outage, tell us up front. Permit fees depend on final scope and are excluded from totals until confirmed.

Insurance letters and older San Pablo panels

If your carrier named the panel brand on a cancellation or non-renewal notice, replacing the whole panel (not hunting for used breakers) is what usually clears the flag. We can provide the kind of before-and-after documentation homeowners use with insurers after a permitted, inspected replacement. More detail: insurance-flagged panels.

San Pablo sits in our everyday service area between Hercules and South Berkeley, so scheduling a look at the panel is straightforward — photo by text or a site visit, then a written price.
