We just moved to a new house, and I've spend the past couple of days off wiring everything up. I've gotten all my standard 20A 115V outlets working, I went to install my 220V lines today and the tools won't turn on.

I installed a slim line 20A double pole breaker (trying to save room, but my first trouble shooting step will be to replace this with a standard double pole) in the box. Connected the white and black wires to the breaker, ground to the ground bar and ran the wire inside. From there it goes to a 20A double pole switch so I can turn everything off and on from inside the shop. I confirmed when the switch is off there's no power to either tool. When it's on I get power to both the white and black lines. These are wired to 20A receptacles. I confirmed power is getting to both the black and white lines of my tools, but neither of them will switch on.

Thoughts?
