Question:

Good morning Charlie, and thank you for your service to the industry. The requirement to have a receptacle within 25 feet of an air conditioning condenser/Compressor unit Art 210.63. Yesterday we had an inspection. We installed a receptacle as required for our units. This is 2-family dwelling with two separate meters. Twenty feet away was a refrigerant unit for the second dwelling. Does our receptacle satisfy the requirement for the other unit even though its source of power is from a different dwelling? What of two buildings, separated from each other, but a proper receptacle is installed on one building within 25' of the other building's refrigeration equipment. Does this also satisfy 210.63? I understand the problems with permitting such an installation but I do not see that the code disallows this situation.

All the best, Jeff Glanstein

Answer:

Hey Jeff thanks for your question and the kind words. Yes. A 125 volt single phase 15 or 20 ampere receptacle outlet must be installed within 25 feet of heating, air-conditioning, and refrigeration equipment and what you describe seems to comply with that. The problem is that branch circuits in dwelling units of multi occupancy buildings are only allowed so supply loads within or associated with that dwelling unit as stated in 210.25. There might be a little debate about the wording about the load, such as a portable tool, used to service equipment being associated with that welling unit but that is probably what the inspector was thinking about.
