NEC 517.14 Health Care Facilities

[jar546]

If a Chiropractor's office in a strip mall has 2 separate services providing power to his patient care areas, do the panels need to comply with 517.14 to each other, even if different services? In this case, the panels serve the left and right side of a common hallway (vicinity).

517.14 Panelboard Bonding. The equipment grounding terminal buses of the normal and essential branch-circuit panelboards serving the same individual patient care vicinity shall be connected together with an insulated continuous copper conductor not smaller than 10 AWG. Where two or more panelboards serving the same individual patient care vicinity are served from separate transfer switches on the essential electrical system, the equipment grounding terminal buses of those panelboards shall be connected together with an insulated continuous copper conductor not smaller than 10 AWG.

Yes but looking for opinions

My opinion, I see no exception for separate services.

Out of my depth there, so no opinion. But, would a chiropractic office even have an essential electrical system? And I'm suspicious that "patient care vicinity" wouldn't include a common corridor.
