Im set for delivery on a MS85 (duel chargers)in a few weeks. My wife has MS100D. Im thinking about duel HPWC in our finished garage. The panel is ~50-75 feet worth of wire run through the garage attic to location. Im thinking sub panel, then split with conduit to each HPWC. Any thoughts on wich AWG to go to sub panel? I was thinking 2awg copper to panel, 3awg to each unit. Im new here, thanks for help!
