Why is it OK to have liquidtight flex and nonmetallic conduit (both having a PVC jacket ) under the raised floor, but not PVC with
a ground conductor in it?

Doesn't 645-5 (d) (2) permit rigid non-metallic (PVC) conduit?

Redsy:

Yes, and the question is really not very clear. I have invited the person who asked this question to come aboard here on theis BB and look for the help he needs. I always bring these types of question here so we can all put our thoughts into the discussion.

Most of the limitations on the use of PVC conduit inside buildings are the result of concerns about the fuel and smoke contributed under fire conditions rather than its performance as a raceway.
