In order to run romex 40A 3 wire + grd out side from basement to second floor kitchen in 3/4" PVC should I strip jacket from romex or is it ok to leave it on? I was told it might cause to much heat inside PVC.

You cannot ever strip the sheathing off romex and run the bare conductors.

You cannot use romex outside.

You have to use indivudal THWN wires or UF wire. I'd use THWN, UF too hard to pull through conduit.

If you strip the outter jacket they become
Thhn conductors. It's just fine to remove the outter jacket.

1. not necessarily correct
2. THHN cannot be used outdoors in conduit.

Absolutely wrong. The conductors are not labeled so you cannot assume they are THHanything.

The NM is listed as an assembly. Removing the outer jacket destroys the listing of that assembly.
