do not stack the red to black. a 220v line gets it by 2 individual 110 sources. the red and black lines each should have their own individual breaker. give me a few min and ill repost how to do it. i wired up my 220v compressor myself from adding the double breaker all the way to outlet then to compressor.

edit. red goes to white, black to black. in typical 3 prong setups neutral and ground are combined. on the "L" terminal i think.

I get home around 9:30. ill look at my compressor and also post pics. please don't wire anything until then lol unless an electrician chimes in.
