Cornish sits at the meeting of Routes 5, 25 and 160, with the Saco River on one side and hills on the others, so most trips to shopping, work or the highway start with miles of two-lane road. For an electric vehicle, that makes home charging the practical plan. About 81 percent of homes in town are single-family houses and roughly 82 percent are lived in by their owners, which means a driveway, dooryard or barn is usually on hand for a Level 2 unit. On a 240-volt circuit, a few overnight hours put back a full day of driving, and leaving home with a full battery counts for more when January cold trims range.
Some village houses may still be on 60- or 100-amp service, since more than a third of the town’s homes predate 1960. An EV charger can hold a draw of 32 to 48 amps for hours, a heavy addition beside a well pump, an electric range and any heat pumps. Goodnow Electric looks at the panel and service before suggesting equipment, whether that is a hardwired unit or a plug-in one, a Tesla Wall Connector or a universal model, on a circuit sized to match. Where the service falls short, there are three routes, each laid out in writing before anything is installed: a smaller circuit, a charger that manages its own load, or a bigger service. If heat pumps are also on the horizon, size the service for both now so the panel is opened only once.
On the incentive side, Efficiency Maine currently has a $200 discount code for a qualifying off-peak charger and pays another $200 after the unit is connected and registered in its app; by default those chargers hold off through the evening peak from 5 to 9 p.m. Village houses sit close to Main and Maple, so the charger often lands in a carriage barn or on a side wall, and putting one on a street-facing wall inside the historic district is something to run past the code office. The state electrical board issues the permit for the new circuit, and an inspector sees the wiring before any wall is closed.
