Not to throw salt on an open wound...
"I'd say that the instructions for the device in question should be the deciding factor. If it says "This equipment must be . . ." then it must be."

Kind of a bad move to find out that HG IS required when the equipment is delivered to a finished office.

Had a 'rough' last week....written on plans "exam room 1" etc....wired in MC. Red sticker...GC had a fit....had a quick with HG next AM.

Patient treatment rooms are HG, offices, reception, halls, etc are 'regular' suitable wiring method.

We have had numerous issues with "flex" space being converted to medical office space and using "existing" wiring, but that's another tale. (Change of Use)
