can a THHN or THW conductor used a GEC be ran outside and exposed to sunlight versus run Bare cooper wire. I looked in article 310 and could not find anything regarding if conductor would have to sun light resistant.
Reason for the question is on an upcoming service the GEC to main water line will need to be run exposed around the perimeter of the house at the soffit line as main water is in the basement and no way go through attic.
I want to run a THHN#4 wire exposed for the GEC.
Thanks.
