220 volt

[Mixedup]

I have a 220 circuit in the garage and have to rewire a plug to a 220 AC unit - I know there is a green wire that goes to the ground - but then the other two - does it matter what side of the plug you wire these two wires to?

Thanks in advance for the info.

Plug - is Male 220 20 amp

White to white, Green to ground Black and red to the Gold screws on the plug. When I did electrical the easy way to remember what went to what was Black (gold) as in Oil. It does not matter which terminal for the 2 positive circuits.

I've only got 3 wires coming out of the ac -- but I am certain it is a 220 unit

as long the green is on the ground, you're good to go with the other 2 on either terminal. The ground is for safety only. No current goes through it to operate the ac unit.

what color are the wires in the AC unit? Is 1 white if so it is a 120V unit.
A 220v should have a white,black,red and ground.

Black white and green ....

The green is ground, the other 2 are 220 to each other. No neutral is required on most 220 circuits. they don't use 110 internally. Some dryers do but they will have 4 wires and the 4th is neutral and reads 110 to both 220 leads. The neutral and ground both end up connected to the same final connection in the breaker box if the ground bonding screw is conected to the white wire (neutral)buss bar.


A white wire is universally thought of as neutral, from air-rover, it was just the wire they had on hand at the time. If the unit is marked 220, it likely is.

Im assuming that you havent upgraded your panel or primary line as of yet, When adding a 220 you need to accomodate your panel and breakers for the new draw. I am saying this based on the fact it sounds like you are not just replacing an old unit because if you were it would be a quick swap out and matching game. Be careful and make sure you know what your doing, 220 improperly pulled can be a beast of its own.

Thanks for the heads up and warning - The Panel and 220 plug and circuit breakers were installed by professional electricians. The Plug iand two breakers as a circuit is for 220 20 amp. The Cord on the AC unit had a 50 amp type prongs - but the AC only pulls 13 ams. I changed out the plug on the AC to a 20 amp type and have run the unit for a couple of nights with no problem - that is after the other DFWstanger helped me in another tread figure out I needed a new torsion mount for one of the motors that had a mount snapped. Alls is good ... unless you see some other technical detail I should concern myself with?
