I just saw an unusual pipe material used as conduit on a feeder to a 400A safety switch. The 4" corrugated plastic pipe was a septic drain pipe, and the fitting at the switch enclosure was a 4" PVC plumbing elbow. This sure seems to be an NEC violaton, but I cannot point to a reference other than 110.3(A)(1) on "suitable for installation." Is there a better NEC reference that prohibits installations like this, or is it actually acceptable to protect conductors in this manner? Thanks and Happy Thanksgiving.
