  • What are your actual anticipated loads? Sizing for 100 (or 80, derated for continuous) amp loads will typically oversize your wires quite a bit from reality. Use aluminum, and tell us if it's going overhead or underground or what...2 AWG aluminum might be a good bet, or big enough for any reasonable load, and some unreasonable ones.
