10 amp, 250 volt receptacle???

Has anyone ever seen something like this receptacle?

A broker that I do a lot of work for just sent me this picture so I don't know the outlet is actually wired.

It appears to be 4 prong, 10 amp, 250 volt. I went to the NEMA site and searched for Mag Nus and 4 prong receptacle but haven't found anything.

Google hasn't turned up anything either.

Kind of hard to figure what it would be used for at 10 amps. I would imagine that low of amperage would rule out dryers and ranges.

Any information would be greatly appreciated.

Jeff, I might be wrong on this and hopefully someone else will confirm this, but...

I believe that's really just an old 120-volt receptacle with two 2-hole, non-grounded configurations. There was a time when plugs came in a variety of prong configurations. The "250-volt" you are seeing is just the maximum voltage, it doesn't mean that it can actually take two hots.

I could be wrong. It happens!
