I am installing a heating system for a large entertainment area in my basement. For convenience, I would like to locate the transformers in a utility room. The wiring run from transformers to terminal boards is approx. 28 ft. Installation instructions say to use #6 wire for this distance.
I have #6 THHN wire. Does this wire need to be in conduit, if it runs through enclosed wall?
If so, are there limitations on size and type of conduit for this application?
