This is wired with 2 hot wires and a ground right, on a 2 pole 15 amp breaker? and will 12/2 with ground wire be ok to use?

Yes 12/2 wire is correct for your unit and if the manufacturer recommends to use a 15A. breaker a 15A double pole breaker is what you should use. You do not need 12/3 as others have suggested because there is no splitting of voltages for components on an air conditioner as there would be in a dryer for instance where the motor of the dryer runs on 120V. and the heating circuit runs on 240V. Both the fan motor and the compressor run on 240V in the air conditioner.

I'd use 12/3 romex and you can do it all with 1 wire. Yes, 12 will work. 12 gauge will carry 20 amps, 14 gauge will carry 15. Upsizing is never a bad idea, though, especially on a fairly long run or something like an ac unit. There are two hot wires (your two legs of 110) and a neutral, and you can ground the box with the bare wire in the 12/3 romex. Definitely a 15 amp breaker, though the wire can handle 20, the ac unit cannot, so size it for the ac unit. Hope this helps!!

the 12 gauge wire is good but if the a/c unit is rated at 15 amps i would use a 20 amp breaker.

You are on the right track there - everything you said is what I've seen done. 12 gage wire will typically run a 20 amp 110 curcuit, so I'll bet you are plenty safe using it on a 15 amp 220 line.

Whoah, whoah, whoah... The unit IS RATED for a 15 amp circuit, 230 volts. I have a similar unit and purchased it because of it's high energy efficiency rating. The max amperage draw for the unit is 8 amps; using 14/2 wire on a 15 amp breaker with two hot wires is ALL you need. Since we are all buying more and more high efficiency unit that consume less and less power, we should expect to see more wiring configurations like this. In my case I had a 60 amp sub panel installed at my mobile home so I could safely run additional modern conveniences. If I use a 20 amp breaker for a unit that is rated for no more than 15 amps, I've just needlessly used up 5 amps of power and thus reduced my ability to run 4 modern conveniences down to just three.

You will need 10- 3 with ground and a 30 amph breaker would be best
