I am looking to ground my array with #6 bare solid copper strung between the rails. I want to carry this EGC down to my electrical room with all of my other strings in conduit. Under 2014 NEC am I allowed to transition this #6 bare into THHN in a junction box on the roof to allow myself an easier pull going all the way to the electrical room? Or will this still have to be a solid wire all the way back?
