240v split

usually a 240 circuit is wired to a double pole on one side of the mains.
if you wanted to could you wire each of the 2 hot wires to a separate single
pole and put one on each side of the mains to keep it more balanced????
would it be good to do this??? would both breakers trip at the same time???

Although the double breaker is on the same side, it is picking up each "phase" if you will. Next time you are in a home store look at a raw breaker panel. You will see that every other contact comes from the opposite side, thus the double breaker is not fed from the same one. If you need two separate 120 volt circuits, install two single breakers, unless you are familiar with multi wire branch circuits and how they are handled.

You could use two single pole breakers, but the handles would need to be tied together with an UL approved handle tie. Wire/zip ties is not approved. Both breakers need to disconnect at the same time. Two single pole breakers may not trip together without the handle tie.
