    Default Help needed with ID of receptacle

    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:

    ECN Electrical Forums: 4 Prong Duplex Receptacle
    ECN Electrical Forums: 4 Prong Duplex Receptacle

    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.
