What is the intended polarity/voltage of the lower receptacles?

And what would likely have been drawing current from these - there is one on an enclosed front porch, and another behind in on the interior of the exterior front wall.

The closest configuration I could find is a 208 volt 30 amp, but that would not be on duplex, it would be a single receptacle.

Sooooo ... got me.

Wow,

Never saw that before.

208v would be three phase. *Could be* but *not likely* on a residential home.

May be some kind of recreational outlet????

Over at Mike Holt they pointed me here:

Appears that this is designed to accept either a 120 or 240 15A ungrounded plug.

I'm still wondering what might have been plugged into it.

Very interesting.

Thanks for the info.
