[RE-wrenches] Enphase and Romex

[Ray Walters]

Thanks Benn, I've also never seen anyone switch to UF, just to wire to 
an exterior outlet mounted directly on an exterior wall of a home.  
Further, the box is usually indoor rated(if it's in the wall) and only 
the exterior cover plate is weather proof.  Both UF and NM have THHN 
inside of them, and it's the THHN that is inside the exterior J box, as 
the weatherproof covering has been stripped off. THHN is damp rated, 
while THWN is wet rated.   Most of that wire is actually dual rated 
THHN/THWN.
Seems to be yet another case where solar is held to a different standard 
than other wiring.
