More Newbie questions:
My current design calls for a single 3/4" EMT conduit run from my attic junction box to the Inverter in the garage. I'm running 2 pairs of current carrying DC conductors (8 AWG THWN-2). Do I need 2 separate insulated EGC THWN-2 wires (12 AWG) per pair, or can I get away with a single insulated EGC conductor? Seems like 2 EGC conductors would be an overkill.
