I was replacing some outlets in a house that was built in the 1950's. I ran across 4 of these outlets. The top and bottom half is isolated from each other. There are 2 120 volt wires, with one going to each side of the outlet.
I have never seen anything like this and everyone that i have showed it too has not either. That is not paint filling in part of the slot at the
top, that is the slot. Really strange.
Above the top portion it is marled AERIEL. Below the top half is marked GROUND. Below the bottom half is marked POWER.
There are no manufacturing make stamped on it just patented ND OTHER PAT'S PENDING.
It is also marked 10 AMPS 250 VOLTS AND 20 AMPS 125 VOLTS.
Anyone know what these were used for?
Thanks in advance.
