Residential Electrical in Baldwin, Maine

Two hundred years of rural building show in Baldwin's houses. Nineteenth-century farmhouses line Route 113 and cluster in the old centers of East, West and North Baldwin, and about 15 percent of the town's homes are older than 1940. Knob-and-tube, cloth-covered cable and ungrounded circuits can all survive in them. Houses from the 1960s and 1970s, around a quarter of the total, commonly have two-prong receptacles and scant ground-fault protection. The roughly 28 percent built since 2000 are mostly wired to modern standards, though many were finished before today's arc-fault rules. A farmhouse that grew an ell, a connected barn or a converted shed over the generations can hold several eras of wiring at once.

Mobile homes, about 16 percent of the housing, have their own issues: aluminum branch circuits in older units that need rated connectors or replacement, feeders sized too small, and receptacles worked loose over the years. Across all three kinds of house, Goodnow Electric replaces knob-and-tube and aluminum runs, grounds outlets, adds GFCI and AFCI protection where code calls for it, traces circuits that trip or go dead, and wires remodels and additions. The draft comprehensive plan points out that state housing law now requires towns to allow up to two more units on a lot with an existing single-family house, and each new unit brings its own circuits and frequently a service upgrade.

There is no town electrical permit. In a single-family home the master electrician doing the work verifies it; anything the state does require a permit for, like apartment buildings or commercial work, goes through the Electricians' Examining Board. Buyers looking at an older farmhouse or mobile home in town can learn a lot from having the panel and wiring inspected before the purchase closes, since a handful of repairs and a complete rewire are very different budgets. Estimates are free and written, and in an older house the panel's spare capacity is checked before any circuit is added.
