I believe if hooked both wires to the same "leg", one could not get 220V. Each "leg" is 180 degree out of phase, and you get 220 between these two. When 110 is desired, it comes between one leg and the neutral wire (ground).

But the rest of your reasoning for a true 220v double breaker is valid. You want to break both "legs" if there is a problem on that circuit, not just one.

I don't mean to be correcting here, but it only is so others who read this get the correct information (or if I am wrong, I get corrected too [img]/forums/images/icons/grin.gif[/img] ).
