I have 2 of those identical Hubbell combo outlets that I pulled from an old liquor store c. 1920's ... I remember seeing those "crows foot" outlets all over the elementary school I went to as a kid, but to this day don't know the purpose unless it was for a floor buffer or something of that sort. The school was built in the 50's, there was a single NEMA 5-15 and a single crows foot 2 gang by the door of each classroom, and one in the cafeteria. the restrooms each had a "Sierraplex" combo 5-15/6-15 duplex kinda behind the door as you enter about 6'+AFF.. What would a school bathroom need 240V for??? [Linked Image]
