I've got three 480 volt plasma cutters my son is going to test at work. He asked me to get them all strapped to a pallet and the plugs installed so he can quickly just plug in and see if the machine works.
OK, I found three 480 plugs. They have X Y Z and G connections. I'll put the green ground wire on the G. Is there a convention for the three hot wires? Red, black and white. Does it matter?
I'm in luck, the group's greatest EE has offered to help re wire to220.
