I have a 500 foot run of 3 conductor 8 gauge copper. I only use 2 of the conductors and ground to connect my 240 volt 9.6 kv microinverter system to the main panel. My question is whether I could use the 3rd conductor to double up on one of the legs reducing voltage drop. I had people say I can't because of "imbalance" and it's probably against code, but does someone have an explanation of why it wouldn't work?
