220 plugs in living room?


My house was built in the 1960's and came complete to me with a 220 VAC plug in the living room and another in the bedroom. Its a strange looking outlet I've never seen before and I was curious if anyone might know what types of things might have once needed 220 volts. I thought about swapping one out for a welder plug so I could watch college football while I did arts and crafts, but I decided the carpet might be too flamable!

Thanks.

Yep, window air conditioners...You could swap them out with 20 amp receptacles. Might as well make use of it somehow.

we used to have one in our living room, not near a window so not for a/c... i thought maybe was for a special vaccum cleaner or something.

There's a few more steps involved with that. He needs to make sure to replace the double pole breaker with the correct size single pole.

I know. And then you have that open knockout that you would need to block.

Couldn't he just make it a MWBC to two halves of a duplex?

There's probably no neutral. Can't do it.

Or, maybe... a NEMA 10-20... gasp. Could we be so lucky as to see the elusive crow's foot receptacle?

10-20? A 3 pole A/C plug? Maybe it will be a t-slot 6-20!!!

It is likely a 6-20, but he said it was odd. Most people have seen a 6-20.

You have never seen a crow's foot 20 A used for a window unit? I have replaced quite a few. Apparently there was a phase in the 60's and 70's where some A/Cs had 125/250 V ungrounded plugs. I don't know why, but I've seen enough 10-20s installed to know that it happened quite often.

I always end up replacing them with either a 5-20 or 6-20
