I am installing an air conditioner, which takes a 230 volt 20 amp circuit. I am unsure if this circuit should be wired exactly like a typical 220 circuit, with 2 hot wires and one ground, and also use a typical 2 bus 220/20 amp breaker. I was told that it only needs a single pole 20 amp breaker, but this doesn't seem right for a 230 volt circuit. Which breaker do I use?

If you want a 230 volt circuit, you have to use a double pole breaker. Each pole will only have 115 volts between it and ground -- the 230 volts is the diffence between the 2 poles.

hello tgarrety,
what u will need is a 20 amp 2 pole breaker that fits your panel, and some #12-2 with ground wire. install the breaker in your panel, connect the black and white wires of the 12-2 with ground to the breaker connect the bare wire to the ground bar of panel. at the ac outlet connect the white and black wires to the gold screws and the bare to the green. a 230 volt is actualy a 220, or 240, the terms interchainge.
