Electrical Panel Upgrades in Lebanon, Maine

More of Lebanon's housing was built between 1980 and 1999 than in any other period, about 37 percent according to the Census Bureau, and the median home dates to 1989. That means a large number of panels now thirty to forty-five years old. Many of those houses were built with 100 or 150 amp services at a time when oil furnaces and boilers did the heating and nobody planned for an electric car. Breakers wear, bus bars corrode where moisture reaches them, and panels from that era often have no open spaces left after decades of added circuits. Older village houses, about 14 percent built before 1940, can still carry fuse boxes or 60 amp services, sometimes feeding wiring that has been added to by several generations of owners.

Lebanon leans on heating oil more heavily than the towns around it, about 67 percent of occupied homes, so heat pumps are the most likely reason a homeowner here starts thinking about the panel. A whole-house heat pump system, a heat pump water heater and a Level 2 charger together can exceed what a 100 amp service can safely carry, and a load calculation shows where the line falls. Goodnow Electric upgrades services from 100 to 200 amps, replaces fuse boxes and Federal Pacific, Zinsco or Challenger panels, adds whole-home surge protection, and coordinates the disconnect and reconnect with Central Maine Power.

Mobile homes deserve their own mention, since they make up about 15 percent of Lebanon's housing. A mobile home is often fed from a meter on a pole or pedestal rather than on the home itself, and upgrading that kind of service means working on both the pedestal and the feeder to the home's panel. The state board's guidance to utilities says a manufactured home outside a park needs no state permit, while any building with two or more meters always does. New services and full service replacements on one- and two-family homes also need an outdoor emergency disconnect. Every job starts with a free written estimate.
