Wire type for a 40A oven

The new wiring for my oven needs to be #8 (40A) 4 wire. Can I use the wire that is like romax (NM) or do I need to use a conduit and use THHN?? I have up size most of my wire in this project and will likely use #6. If I use conduit, will the grey PVC meet code??

Depends on local code.

National Electric Code, yes.

Another words, every City makes changes to what they think is best, in this case you should ask your city's electrical inspector.

I see something that has confused me for about two months now. I saw ENT suggested to be used in a certain application and thought it was strange that it was suggested.

Bolide, ENT is not the grey pvc rigid conduit. Grey pvc is conduit, not tubing and is referred to as RNC, rigid non-metallic conduit.
ENT is electrical non-metallic tubing. That is the blue corrugated flexible tubing often referred to as "smurf" or "smurf tubing".
If you have a 2005 handbook you will see what I mean on pages 396 & 399.

Yes, the NEC allows a freestanding electric range circuit to be wired with 8/3g NM-B (Romex) cable and a 40A DP breaker for ranges 12kW or less; OR 6/3g NM-B (Romex) cable and a 50A DP breaker for larger ranges. Almost all ranges are less than 12kW, but feel free to use #6 if you want.
