I've just received an air conditioner (http://www.ajmadison.com/cgi-

three prong, two running vertically.

The AC arrived, and the plug has three prongs, two running
horizontally.

Is there an adapter I could use? I don't know much about this stuff.

Thanks.

You have a 220V A/C. Your plug is 110V. You have 2 choices

1) return the A/C
2) Convert the plug to 220V. If it is a dedicated outlet, it is fairly
easy to do. if you have not worked with electric before, it might not
be. But basically you replace the single breaker with a double pole
breaker ( 15 or 20 A depending what size wire you have), put one hot
leg on one pole of the breaker, then remove the circuits neutral leg
and put it on the other pole of the breaker.( There is no neutral in
220V, just 2 hots) change the plug, and your good to go.

Of course you would have to see if you have room in your panel for a
double pole breaker.

The chances the existing 120V outlet is a dedicated outlet are very
low.

A 3rd option would be to install a 240V outlet for the AC unit.
