Used AL on my own house.
Being a cheep middle aged white guy is my only sin.You will burn in heck for all eternity.

Anything that is listed to be in sunlight. THHN, XHxx are both common.is there a specific type wire used for service in a riser? especially 4/0 and above. i have never seen risers with Aluminum larger than 4/0.
I usually see URD type inside conduit for riser. Is there another insulation type that is used??
