I'm being asked if I can connect a hot water heater that serves an apartment to the building's house panel. Metering wise, this is an issue, but is there any code section that prohibits this?
Per the 2020 NYC energy code:
R404.2 Electrical energy consumption (Mandatory). In all buildings having individual dwelling units, provisions shall be made to determine the electrical energy consumed by each unit by separately metering individual dwelling units.
Per the NEC, sections 210.25 (A) and (B):
(A) Dwelling Unit Branch Circuits. Branch circuits in each dwelling unit shall supply only loads within that dwelling unit or loads associated only with that dwelling unit.
(B) Common Area Branch Circuits. Branch circuits required for the purpose of lighting, central alarm, signal, communications, or other needs for public or common areas of a two-family dwelling, a multifamily dwelling, or a multi-occupancy building shall not be supplied from equipment that supplies an individual dwelling unit or tenant space.
I don't see anything in these sections that prohibits this. Is there another section?
