EV charger installation in Prince Frederick, Maryland.

Prince Frederick is the county seat, so it sees a mix of housing stock: older homes close to the historic core and courthouse, and newer construction further out along Dares Beach Road and Route 231. A lot of the older houses were wired for a 100 or 150 amp panel decades before anyone was plugging in a car overnight, and that is the single biggest question we get asked here. Maryland adopted the 2023 National Electrical Code statewide, and Article 625 covers exactly this kind of circuit, so a permitted Level 2 install starts with a real load calculation, not a guess.

We handle the panel evaluation, the permit paperwork with the county, and the inspection, whether your Prince Frederick home needs a straightforward 240V circuit off an existing panel or a service upgrade first.
