Hi,

I have a wire that seems to have only to conductors in it. It's a gray
wire in which the plastic sheath is tight over the wire. The two wires are
about 1/4" apart. I'm not sure how to better describe it.

It seems to be connected to a double breaker and carrying 240V to the A/C
unit. Does that make sense? I guess if the two wires are 120V out-of-phase
then the AC current can just flow from one of the wires to the other?

I'm trying to make sense of this for my own education, but also wondering
what kind of wire I would need (12/2?) to replace this one (it's routed
stupidly).

Thanks,

Aaron

Is there a ground wire at all? I know UF cable is gray (well the sheathing
is). Example:

http://electrical.hardwarestore.com/...667888.aspxYou have to look at the breaker that it is hooked up too. Some units onlyrequire a 30 amp breaker in which case you would use 10/2 with ground or10/3 with ground if for some reason you need the neutral. If you are goingto replace it, then maybe think about setting a disconnect like this:http://www.lowes.com/lowes/lkn?actio...&lpage=noneand get one of these and use #10 thhn wire inside to go from the box to theAC unit (look at the picture on the bag):http://www.lowes.com/lowes/lkn?actio...B&lpage=noneOf course this is just an example for a 30 Amp system.
