I was having a conversation with a coworker about this and we do not agree with one another. What are the opinions of those here at Mike Holt ?
Article 517.13 Tells us that all branch circuits serving patient care areas shall be wired using a metal raceway system, or a cable having a metallic armor or sheath assembly that qualifies as an equipment grounding conductor that meets 250.118. It also tells us that we must have an insulated copper grounding conductor sized using table 250.122.
Heres were we disagree:
Exception No. 2 to article 517.13 .
I say that exception No. 2 ONLY waives the use of the insulated Grounding Conductor requirement.
In other words, lets say the lights switches are outside of the exam room and the luminaires are over 7 1/2 feet off the floor.
I say that according to Exception No.2 an electrician must still use a metallic raceway sytem or cable having a metal armor or sheath assembly that qualifies as an equipment grounding conductor as required by 517.13(A), BUT does NOT need the insulated copper grounding conductor required by 517.13 (B).
I base this on the definitions of Patient care AREA and Patient care VICINITY. The entire room is a patient care AREA but only a part of it is the patient care VICINITY.
My co-worker says that I'm wrong and that as long as the luminaires are over 7 1/2' off the floor and the switches are outside the room, an electrician can wire the lights using regular MC cable instead of using a HCFC cable or metallic raceway system.
