230v Special Electrical Outlet?

So I ordered a window AC unit from Amazon, refurbished, super good price, it said it needed a special 20amp electrical outlet. I'm figuring it's the normal 20amp outlet where the left prong is horizontal. Turns out, the plug looks exactly like that, but it's the right side that's horizontal, not the left side. I cannot find this outlet ANYWHERE. Checked Lowes, Home Depot, online, I just have no idea where to find it. I've looked up 20amp, 230v, AC outlet, etc, can't find anything.

Can somebody please help me find this. The breaker box it's getting hooked up to is in my garage, all 20/30 amp breakers so I'm sure it can handle it. I just can't find the outlet to wire the damn thing up.

 

What you need is NEMA 6-20R and that outlet is readily available at any hardware stores. You are probably confused because those outlets are made to accept both 15A and 20A plugs.
It accepts plugs with both prongs horizontal (240V 15A) and plugs with only right side horizontal (240V 20A).

You will have to run a dedicated 12-2 cable from the breaker panel and feed it with 2 pole 20A breaker. Most likely you will need to add a breaker.
You can wire both white and black wires to each pole of 2 pole breakers. You also need to mark white wire with electric tape or some other means to mark it as hot (although most people never do).

 

Nope, that's the one I just bought and have to go return... I need that outlet but flip flopped horizontally. The Right side of the outlet needs to be horizontal, not left side.

 

It looks like an Amana PTAC uses that configuration.

Did you click the link above that Lambition posted? That has a horizontal hole on the right (and left if needed). Otherwise if that is not correct you need a 5-20R which is 20 amp 120 volt.

 

I am such an idiot. I looked at that link like 5 times and just now noticed it's what I needed. Too much work and not enough sleep... Thank you guys very much. I wish there was an extension cord like that 6-20R but I suppose running another outlet isn't that big of a deal!

 

Yes, you want to wire a new receptacle, not use an extension cord.

 

Where would you plug an extension cord?
Do you already have a 240V outlet nearby?

 

Definitely get the 6-20R if its a 240V circuit/appliance. My son recently smoked his x box while staying at my grandmothers after she died. My deceased grandfather knew just enough electric work to be dangerous (we called him Rube Goldberg) Lol! They had a long gone 240V window unit but the receptacle remained which was a 20A 120V, Im guessing he changed the cord plug just to get it working quickly without hunting down parts. While hospice was at their house the 120V oxygen concentrators kept blowing while plugged into that same outlet, Im surprised they worked that long. Some switch mode power supplies are 120V 220V rated but some arent. Suprised my grandmother never plugged her old Electrolux canister vac into that circuit. Would have sucked real good for a few seconds followed by burning magnet wire or disintegrated rotor/fan impeller!
