i failed an inspection for exan rm. in slab rough I used pvc boxes and pipe. the inspector says only metal boxes and rigid is allowed in exam rooms. I cannot find it in the code book. Please help.
517.13(B) (BTW what year NEC are you using?) is in addition to 517.13(A), it doesn't relieve the requirements of 517.13(A)
517.13 Grounding of Receptacles and Fixed Electric Equipment in Patient Care Areas
Wiring in patient care areas shall comply with 517.13(A) and 517.13(B).
