Assemby Article 518

article 518.4c wiring methods refers to emt tubing or rigid nonmetallic conduit as acceptable. In this case would rigid nonmetallic conduct mean rigid pvc???

they are one in the same. note there are restrictions as to when RNC can be used.

by restrictions I presume you are referring to 518.4c1,2 where the 15 min finish rating is required for the walls/ceilings
