According to Article 517 (Health Care Facilities), 517.13-Wiring Methods states that "All branch circuits serving patient care areas shall be provided with a ground path for fault current by installation in a metal raceway sytem, or a cable having a metallic armor or sheath assembly. The metal raceway sytem or metallic cable armor or sheath assembly shall itself qualify as an equipment grounding retun path in accordance with 250.118." Sounds like PVC will not meet NEC criteria.

You said feeder, branch circuits are required to be in metal, I know of no code that does not allow feeders to be in plastic.

I haven't seen too many individual therapy rooms with a main feeder serving it. Are we all working off of the same definition of feeder and branch circuit?
