I have to run an isolated ground circuit from a L.I.M panel in a hospital O.R room for operating lights.
Ive done this many times in the past in different hospitals and always used EMT.
The supervisor i have now is dead set on using PVC.Inspection never mentioned a problem with past installations.
I looked it up in the code and they do specify PVC unless The building code states otherwise.
I don't have a building code book for Ontario but believe PVC not allowed in hospital construction.I don't know if it's ft6 rated or not.
Since the supervisor wants PVC thats what i will do and see what the CCS inspector has to say when he sees it.
I can't really call him to ask now and don't want to bring it up after the fact so any clarification would be greatly appreciated.
Another possibility would be ISO AC90 but does it come with brown and Orange and would it be legal for a retrofit?Ive also seen regular ac90 used in some older installations.
