Vintage Receptical
Here is a receptical in my uncle's house.
It still works.
between A&C;A&D;D&B; and D&C there is 120V
Between A&B there is 0 volts.
Does anyone know what this could have been used for?

At one time, there were two competing designs for plugs. Harvey Hubbell Liked the kind where the blades were in-line, like the slots on a NEMA 6-15 today. But the parallel blades were gaining in popularity, so manufacturers came up with the receptacle you have. It accommodates both plug types.
Contrary to what some believe, it is NOT intended for either 120 or 240. It is meant to be used at 120 V.

You can pretty well date the receptacles like that to about a 10 year period. I think it was the 30's, if I'm not mistaken. Like the other guys said... two competing designs for 110V receptacles, and for a period of time many manufacturers accommodated both designs in the same receptacle.

I agree with you. The OP either made a mistake or it was wired wrong. Because D-C should have the same hot conductor feeding them both.

I saw one of those for the first time ever 2 weeks ago. It was yoke mounted though.
It was in a 1960's house. The owner was 'handy'
Got paid a ton to fix everything the owner did.
When will people learn that it's cheaper to hire an EC to wire it right, than to fix it after it's wired incorrectly.

Thanks for the replies. That does make sense. I will recheck the voltages tonight when I go to his house to assemble our new grill. I was going off memory to state the voltages so I could be wrong. I will repost my findings from tonight.

I have a duplex receptacle with the same configuration, removed from a friends house years ago.
