Yes you can tie pvc conduit into a metallic box. Other types of wire have a sticky rubber sheathing that makes them almost impossible to pull.

Thhn thermoplastic high heat resistant nylon coated is the best wire for pulling through pvc conduit. Ok as an electrician i have always believed thhn wire could not be run in walls etc. Put an lb behind the panel to make the turn into the panel and use sweep 90 s for the turns from vertical to horizontal at the rafters. Now i am being asked for a code reference stating thhn can not be run inside residential walls without protection.

While one person holds the flashlight the other person should use a staple gun to run the wire along the rafters from one entry hole to the other. If you choose to run pvc for protection above the rafters then thhn wire is the correct product to use inside the pvc. Yes you can use metallic or non metallic conduit but it must be electrical conduit. No you cannot run thhn open the same as you would nm cable.

Can anyone point me to the proper place in the 2011 book. Personally to do what you propose i think once you are done doing it all in conduit you ll wish you had spent the 100 on romex.
