If the fixtures are located more than 7-1/2-feet above the floor and switched from an area outside the patient care are, they donít need to have the redundant ground so, if that's the case, regular MC should be okay there. As I understand it, if the wall switch is located more than 6-feet away from the edge of the bed, it would generally be considered as outside the patient care area.
IMO, 517.13,B exception #2 in the 2011 NEC is improperly worded and misleading. The way it references 517.13,A makes it sound like you have to have the redundant ground, which would make no sense, since it negates the purpose of the exception even being in article.
Do they have permanent fixed water and drain connections for the dialysis unit, like in a clinic?
I guess technically the area would become a patient care area, but in the hospitals, those portable hemodialysis units just roll into the room and they run long flexible lines to hook up to the sink faucet for water supply and drain them into the toilet of the patient bathroom. They have all the filtration tanks mounted on the back of the cart.
The peritoneal units just look like bags hanging from a pole with a cycler unit and a drain line or bag.
