Your electrical panel is the backbone of your home's power system. When it's undersized, outdated, or showing signs of wear, every circuit in the house feels it. Clayton homes built in the 1970s through the 1990s often use 100-amp panels that were sized for a fraction of today's typical electrical load. Add an EV charger, a heat pump, or a kitchen remodel to that aging setup, and you're asking a small panel to carry far more than it was designed to handle. Mr. Electric of Concord CA serves Clayton and the surrounding Contra Costa County communities with licensed electrical panel upgrades and replacements, performed by Clayton electricians with an average of 10 years of field experience. We pull the necessary permits through the City of Clayton, coordinate the inspection, and test the system before we leave. The Neighborly Done Right Promise® backs every panel upgrade.

What Clayton Homeowners Should Know About Panel Capacity
Older panels in Clayton neighborhoods like Regency Park, Oakhurst, and the areas near Mt. Diablo Boulevard have two common problems. First, many were installed at a time when households had less electrical needs, meaning they weren't designed to accommodate electric vehicle charging stations, induction ranges, home offices, or whole-home air conditioning systems. Second, some panels from that era were Federal Pacific or Zinsco-branded panels, which have documented safety concerns and should be replaced regardless of age. A standard upgrade moves you from 100 amps to 200 amps. Larger homes or properties with dedicated circuits for workshops, hot tubs, or EV charging infrastructure sometimes need 400-amp service. The right size depends on your current load, your planned additions, and what the utility connection at the street supports. Our Concord electricians walk you through all of that before writing the quote.
Permits are required for panel upgrades under the City of Clayton building codes, and that's not a step to skip. A permitted and inspected panel is documented for your insurance company and shows up correctly in any future home sale disclosure. We handle the permit application, schedule the inspection with the building department, and make sure the final paperwork is in your hands.
