Thanks. That's the answer I was looking for. I've never seen a cord and plug connected furnace around here.BBQ said:210.63 Heating, Air-Conditioning, and Refrigeration Equipment Outlet. A 125-volt, single-phase, 15- or 20-ampere-rated receptacle outlet shall be installed at an accessible location for the servicing of heating, air-conditioning, and refrigeration equipment. The receptacle shall be located on the same level and within 7.5 m (25 ft) of the heating, air-conditioning, and refrigeration equip-ment. The receptacle outlet shall not be connected to the load side of the equipment disconnecting means. Exception: A receptacle outlet shall not be required at one-and two-family dwellings for the service of evaporative coolers.
We get them all the time but most furnaces and boilers here are not listed for cord and plug connection so doing so is a code violation.I take it your town has never been through a winter storm. We had a few where power was out for days at or below zero. Linemen and people with gennies where really wishing the thing was on a cord.
