I'm powering an electric door hinge in a hospital emergency department treatment room. The critical branch panel of the emergency system is where I'm instructed to pick up the power.
Can I use hospital grade AC Cable or do I need install EMT ?
 
If it is a retrofit you can use 517.30(C)(3)(3)(c), if the wall is open you would need to use EMT.

I would agree with barbeer. It's not required to have a redundent ground so you would not need to use hospital grade AC cable.

John, how do you figure this doesn't need to meet the requirements of 517.13?

It is a treatment room so it is a Patient Care Area.

I agree it MAY fit 517.13(B) or it may not, we can make assumptions though. I would guess you cannot make "contact" with the equipment, in my mind it is above the ceiling?

Assumptions or not, even if it is above the ceiling it "must" still be in a metalic raceway that meets the requirments of being an EGC and have an isulated EGC as well so all of 517.13 is applicable.

If we were talking about a Luminaire above 7.5' you could forget the insulated EGC but, this isn't a luminaire. See Exception No 2 to 517.13(B)

How does one address the 6' beyond the perimeter of the patient bed location in this area??

Charlie, it is still in the "Patient Care Area" it is just not in the "Patient Care Vicinity"

Patient Care Area. Any portion of a health care facility wherein patients are intended to be examined or treated. Areas of a health care facility in which patient care is administered are classified as general care areas or critical care areas. The governing body of the facility designates these areas in accordance with the type of patient care anticipated and with the following definitions of the area classification.

Patient Care Vicinity. In an area in which patients are normally cared for, the patient care vicinity is the space with surfaces likely to be contacted by the patient or an attendant who can touch the patient. Typically in a patient room, this encloses a space within the room not less than 1.8 m (6 ft) beyond the perimeter of the bed in its nominal location, and extending vertically not less than 2.3 m (71/2 ft) above the floor.

But a door doesn't fall under the criteria from what I can see.

Also just to defend my self, we don't do hospitals here in CA so I very well could be wrong.
 
Roger nailed this one with his first post. it is a Critical Branch Circuit so 517.30-C-3 is applicable which requires Non-Flexible Metal Raceway.

That's one way to cut back on health care costs. But what do you do with all the sick people?? Ship them to Nevada?? :)

Mexico.:smile: It's just as close and it's cheaper.

Guess I could have been more specific. The local AHJ's don't do hospital. We have state inspectors for that.

We only do outpatient clinics and denists.

Thats interesting. Here the locals and the State people each get their turn. It works pretty well, except when they disagree. I've only had that happen on paper - over a minor point like if automatic egress doors belong on the Life Safety branch, or the Critical Branch.
