Wires not color coded. Also according to manual the 4.0 is 2 wire output, and mine has 3 wires coming out together. --- From what I can tell from the manual, some of the 4.0's did have 3 wires in order to get 220, at 1/2 amps. The 110 side is 33.?. and 220 would be around 16.5 amps. Gotta dig deeper into the unit. Did get screen up big enough to actually read the number's in the manuals. Had to haul compost today so didn't get to do much on anything else!
