Is 517.19 D stating that the panelboard feeders for critical care areas are required to be a continuous metallic path back to the source?

Or is PVC acceptable?

PVC seems fine. It says, if a metallic raceway is used, not a metallic raceway must be used.

I would think anything run underground would be PVC.
