10/3 Romex with Conduit
We're wiring a circuit between an electric panel and a disconnect box through the basement and garage. In the basement it can be run along the ceiling beams and does not require conduit piping. In the garage it will be 2 feet off the ground, therefore it does need conduit piping.
Using normal metal EMT conduit and Romex 10/3 NM-B, I had two questions:
1) Can I run a single Romex cable the entire span? If I do, do I need to remove the cover around the Romex cable once it enters the pipe or can I leave it on?
2) What size diameter is required for conduit? The web seems to suggest 1/2 is sufficient, but I've had arguments with a friend of mine who believes 3/4 is required for code in NJ.
