Article 210

Branch Circuits

210.63 Heating, Air-Conditioning, and Refrigeration Equipment Outlet

The words “on rooftops and in attics and crawl spaces” and the exception were deleted so that this rule would coordinate with the mechanical code. This section now reads:

A 15 or 20A, single-phase 125V receptacle outlet must be installed at an accessible location for the servicing of heating, air-conditioning, and refrigeration equipment (HACR) on rooftops and in attics and crawl spaces. The receptacle must be located within 25 ft. and on the same level of the heating, air-conditioning, and refrigeration equipment. The receptacle outlet cannot be connected to the load side of the equipment disconnecting means. Figure 210–8

Author’s Comment: This rule does not apply to ventilating equipment.
Intent: The changes require a 15 or 20A, single-phase, 125V receptacle outlet be located within 25 ft. of heating, air-conditioning, and refrigeration equipment (HACR) for all occupancies, including one and two family dwellings. This receptacle must be GFCI-protected if it is located outdoors [210.8(A)(3)] or in crawl spaces at or below grade [210.8(A)(4)]. Previously this rule only applied to roof tops.
Author’s Comment: The outside 15 or 20A, single-phase, 125V receptacle outlet required for dwelling units [210.52(E)] could be used to satisfy this requirement, but only if the receptacle outlet is located within 25 ft. of the equipment.
