Ever seen one of these? I didn't try plugging anything in, but it is still live. Only one in the house, in a basement area

I come across them every once in a while in the older row homes here in Philly.

I'd say a NEMA L1-15R maybe?

Looks like a 2-wire 15amp twist lock

Twist-Lok plugs and receptacles are still used quite a bit in industrial applications.

My old table saw has a cord with a plug for that outlet, plus an adaptor for regular. It will run on either 120 or 240 depending on internal connections. So those outlets could very well be 240 v.
