Dental office in RV

[wbalsam1]

A dental office, which has invasive procedures involved in the normal dental work being performed onboard, has been installed within a 40 feet recreational vehicle. Should the 120 volt wiring contain a redundant grounding means for patient care area as per Article 517?

While I would like to say yes, I wonder how you would achive that. You might want to check with whomever is in charge of medical facilities for your state.

A patient care area is part of a health care facility which is defined as "buildings or portions of buildings....." and I would not consider a recreational vehicle to be a building, either permanent or movable.

I think that is a very good conclusion. I also don't know why B&S would be looking at an RV, now that I think about it.

So then this space is not a patient care area even though patients are cared for with invasive procedures?

Well you said RV, now did you mean modular or mobile home. Not that I would inspect either in the this state, they're inspected by the state.

I would agree that it says "buildings or portions of buildings..." An RV is not a building, though some may argue that it's a structure by definition.

Wow! Talk about a "tiger by the tail", I'm glad this one is yours, not mine.
I see a number of "arguments". It doesn't fit the definition of an RV in Art 551, and I can see the argument that, from 90.2(B) that it isn't even covered by the NEC. I think my first step would be to go back to whomever "certified" the original wiring to see if there is any useful info there. From a safety point, the same potential hazards exist as in a 517 jurisdiction.
Is the power self contained ?

Yes, the power is from a generator which is onboard. The RV is a 40 feet long tag-axle motor coach. Dental patients have appointments with the Dr. who travels on this coach and performs invasive procedures.

The Don Quixote side of me would be concerned; the old man (perhaps_ more logical side) would have me wave as I drove by
Best of luck.
