Electrical Panel Upgrades in Freeport, Maine

Freeport has put a number on its electrification. The Climate Action Plan approved by the Town Council in December 2024 tracks residential heat pump permits as a metric and models about 1,750 new residential installations between 2024 and 2030, and nearly half of the residents who answered the plan's survey said they already had one. Every heat pump that takes over from an oil boiler shifts winter heating onto the electric service. In a house built before 1970, which the plan says describes 40 percent of Freeport's homes, that service may be 100 amps or less, with a panel that was already crowded before anyone thought of heating with electricity.

Goodnow Electric replaces fuse boxes and aging or problem panels, including Federal Pacific, Zinsco and Challenger equipment, upgrades 100-amp services to 200 amps, and installs whole-home surge protection. Sizing is done on paper first: a load calculation adds the heat pumps, heat pump water heater or EV charger on your list, so the service fits the house you are heading toward rather than the one you have now. Freeport also has about 6 percent mobile and manufactured homes, whose services, feeders and grounding follow their own rules and are worth checking before new load is added to them.

The permit is local. Freeport's Codes Enforcement office issues electrical permits through its online system and inspects the work, asking for two business days' notice for an electrical inspection. Goodnow Electric submits it online, arranges the inspection and works out the meter pull and reconnection with Central Maine Power. Under the code Maine now enforces, a complete service replacement on a one- or two-family home needs an outdoor emergency disconnect, and on a house in the downtown historic district, where the meter and disconnect land on the facade deserves thought. Estimates are free and written, and they spell out the meter socket, mast, grounding and panel work so there are no surprises on the day the power is off. On a house with rooftop solar, the inverter connection and any backfeed breaker are reviewed as part of the new panel layout, since the town's high share of solar homes makes that a common question.
