Don't know what type this would be called, but it is a DC outlet in the floor of a room at Biltmore Estates in Asheville, NC. Part of the original electrical system. One of the first private homes with its own self-contained power station. Early 1900's

'Obsolete' is what they'd be called now!

Somewhere, there has to be an old electrical catalog where they have them listed.

Another example of a really dumb nomenclature scheme. A simple letter tells you nothing of interest about the plug type, e.g. number of pins, pin size/shape/spacing, etc.

And what happens when the number of plugs in use becomes 27? Will they start using lower case letters to ensure further confusion?

Also, there are still plenty of older homes with sockets that look like type A with equal-size slots. I don't see that style on this list.

Some (type C & L) look as if the plug could be inserted in more than one orientation.

The Chinese power tools with 3 prongs electric socket Type-G that I have encountered so far, have only two wires in the cable!! The third prong is just a bluff.
