The Blue Seas calculator says for the voltage drop you need 10 gauge, which has an amp capacity of 40! For the amperage you need ABYC says 18 gauge, so somewhere in between is where I'd be.

That is huge. My question is have I misinterpreted the tables? Also, what influence does the ground (return wire) gauge on this stuff have? Alexander M.
