thanks alphabet - correct, it's a 240v panel. Okay, I think I was confused. I actually want the breakers on the same side next to each other - not on opposite sides - correct?
Is that because when you install a double pole breaker it's actually using 120v from each side? So if my 2 independent 15a breakers are on the same side and right next to each other, they are actually using the opposite sides anyway - right? Are the sides called "phases"? or something like that? Sorry I don't know the technical words for most of this stuff
