200A and 400A service upgrades for Essex County, MA homeowners. We replace aging panels safely, cleanly, and to code — so your home is ready for EVs, heat pumps, and everything modern life demands.
Most homes in Essex County were wired with 100-amp service in the 1970s and 80s — designed for a world of incandescent lights, a single refrigerator, and maybe a window AC unit. That world no longer exists.
Today's homes run EV chargers (Level 2 requires 50A dedicated circuit), heat pumps (30–60A), electric dryers, induction ranges, and home offices. A 100-amp panel can't support all of this simultaneously — and trying will trip breakers, damage appliances, and in the worst cases, start fires.
⚠ Federal Pacific & Zinsco panels: These brands have well-documented failure rates. Their breakers can fail to trip during overloads, creating serious fire risk. If you have one, don't wait — get it assessed now.
Not all panel upgrades are equal. A proper job isn't just swapping the box — it's upgrading the entire service entrance, pulling permits, coordinating with the utility, passing inspection, and leaving you with a clean, labeled, code-compliant system you can trust for the next 30 years.
💡 Permit matters: Unpermitted electrical work can void your homeowner's insurance and cause problems when you sell. We always pull permits.
Most homes upgrading for the first time go to 200A. But if you're planning solar, a battery backup system, multiple EVs, or a large home addition, 400A gives you the headroom to do it all — without having to upgrade again in five years.

Massachusetts follows the National Electrical Code (NEC) with state amendments. MA requires permits for panel replacements, utility coordination, and inspection sign-off before the work is considered complete. Most townships in Essex County also require a licensed master electrician to pull the permit — not just a journeyman or handyman.
