Rigid Nonmetallic PVC Conduit Schedule 40 question?

Yes, derating will stop him before he meets the fill requirements.
This would depend on the circuit length after he transitions from the conduit.

If the conduit is 4 feet long but not longer than 10 feet and the cables extend 40 feet from the point of transition (end of the conduit) then I would not have to derate the cables.

You are correct, I missed that article.

I'm very impressed Cow....not many are aware of that. My guess is that you are going to be correct with having to derate the cables though.... also as you know Chris was correct in applying 312.5(C) along with the possibility of using 310.15(A)(2) Exception 2 he may not have to derate.
