Electrical Panel Upgrades in Gorham, Maine

Gorham still leans heavily on heating oil. About 60 percent of occupied homes heat mainly with fuel oil, according to the Census Bureau's 2020-2024 American Community Survey, against about 14 percent on propane, about 12 percent on piped gas and only about 8 percent on electricity. As households swap oil boilers for cold-climate heat pumps, each outdoor unit brings a dedicated 240-volt circuit, and the heat pump often arrives alongside a heat-pump water heater or an electric car. A panel that handled a boiler, a well pump and a kitchen comfortably can run out of both space and capacity once the second or third of those loads is added.

The town's rapid growth means a wide spread of equipment. About a third of Gorham's homes were built in 2000 or later and about 18 percent since 2010, so a large share of houses already have 200-amp panels, though often with few open slots. The older layer is where upgrades are most needed. About 14 percent of homes predate 1940, clustered in Gorham Village and the outlying villages of South, West and North Gorham, Little Falls and White Rock, and many 1960s and 1970s houses still carry 100-amp services, fuse boxes, or Federal Pacific, Zinsco and Challenger panels that are worth replacing on their own merits.

About 5 percent of Gorham's housing is mobile homes, which usually take power from a pedestal or pole-mounted service with its own disconnect; upgrading that service and the feeder to the home follows different rules from a house. Gorham's Code Division issues residential electrical permits through its SmartGov online system, with paper applications accepted through October 31, 2026, and inspections are by appointment. Goodnow Electric files the permit, books the inspection, and coordinates the Central Maine Power disconnect and reconnect so the house is without power for as short a time as the work allows.
