Does anyone know the max gauge wire the HPWC will accept. The installation manual mentions the ground
wire will only accept up to #4AWG, but they don't explicitly talk about the main contacts. Normally for 100
amp service you need #3 wire in Cu. But for a long run, #2 will have less voltage drop. Anyone know
what those lugs will take?
