I am trying to convert my new ridgid jointer to 220 from the pre-wired 110v. I have an established 220v 20a dedicated circuit modeled after a window AC circuit. It works fine for my table saw, but when I plug the jointer into the outlet, turn it on it trips the breaker immediately. I followed the wiring diagram for the motor. I upgraded all the power supply to SO cable 12-2 (white/black/green) (white tagged hot) the plug is a 20a/250v. What's going on??? The factory switch is labeled for 250v as well. Factory directions for converting to 220 had me attach the grounds to the ground post on the machine and that popped the circuit, then I thought to just wire nut the grounds together and still it tripped the circuit. Any suggestions? Thank you.
