He is still suppose to abide by the 50' rule if he is using PVC or innderduct.

Innerduct, yes because it is not a listed conduit or raceway. But I don't remember the NEC making any stipulation as to what conduit could or couldn't be used. It just says "conduit or raceway". I'll look but I don't think I'm wrong.

But keep in mind that there may be local ammendments that prohibit PVC or limit its use within a structure.
