Electrical Panel Upgrades in Eliot, Maine

More than 60 percent of Eliot homes still heat with fuel oil, the highest share among the towns along this stretch of the Piscataqua, and that shapes almost every panel conversation here. An oil boiler draws very little electricity. The heat pumps that replace it draw a great deal, especially on the coldest nights, and a house that got by on 100 amps for decades can find itself short once a ducted system or three wall units, an electric water heater and a car charger join the load. A load calculation done before the heat pump is ordered saves the surprise of a service that cannot carry it.

The age of the house sets the rest of the job. About a quarter of Eliot homes predate 1940, and those farmhouses often have services that were added piece by piece, a fuse box feeding a later breaker subpanel, or a 60-amp main that was never replaced. Homes from the 1960s and 1970s may carry Federal Pacific, Zinsco or Challenger panels with breakers that many electricians recommend replacing. Newer houses, and Eliot has a lot of them, with about 17 percent built since 2010, usually start with 200 amps and need only a check that there is room for the new circuits.

The paperwork in Eliot is different from many towns. The town has stopped issuing electrical permits and performing electrical inspections, and it no longer tells Central Maine Power that a service is ready to energize. Under its notice, the responsible licensed electrician sends Form 1360 directly to CMP, and where a certificate of occupancy is involved, gives the town an affidavit or equivalent documentation. Goodnow Electric handles that step and coordinates the disconnect and reconnect with CMP. State guidance to utilities also calls for an outside emergency disconnect on new or fully replaced services for one- and two-family homes, so the new equipment on the exterior includes one. Whole-home surge protection is worth adding in the same visit, and so is labeling every circuit in the new panel, something many older Eliot panels never had. Estimates are free and in writing, and they spell out what the new service will carry.
