TS3650 220v Wiring

[wmopnc]

I recently purchased a TS3650 and wanted to wire it for 220. I think the instructions are find but what I didn't want to do was cut the end of the plug off. I'd rather run a new cord directly from the switch to the outlet. Looking for suggestions. I bought about 20' of 12/3 wire and have a 20amp circuit.

I am also challenged because I don't know which side the white and black wires go on the plug I purchased. I'm gathering from what I've learned that they both carry power but wasn't really sure how I should connect them to the switch end. Any Suggestions? Any pictures of this kind of setup would be helpful as well.

Thanks in advance.

The black and white wire can go on either terminal on the plug. Both carry power from a double breaker. Just make sure the ground wire is on the proper terminal.
