It has a horizontal bit, a vertical bit, and then a ground.
He said plug, and this looks like what an Edison 20A, 110V plug to me. Pretty much the same as yer standard extension corp plug, but with one of the current carrying conductors turned 90 degrees.
This female connector is designed for 125V (110 - 125V) to accept both. Your apt is probably designed to take 15A plugs, so the receptacles only have the parallel connectors.
Are you sure that it's a 220V machine? Not that they don't make connectors in that shape for 220, but it's not common. Keeps folks from making that mistake.
Anyhoo, 220V is usually fairly common in US homes, because that's what is sent to US homes. It's just sent along with a center tap from the 'pole pig', or transformer, so that there are two 110V legs available. The power that you are being sent is 220V, you're just using half of it at a time. Find your breaker box. Every other breaker, vertically is the other half of that 220V. Putting in a 220V breaker is simple. Getting that wiring to your machine, and doing it safely, and up to local code is the hard part. I'd be wiling to bet that you have 220V just hiding in a closet somewhere. And if you don't, I'd better get cracking on this 110V two-group project soon! ; >
