Hi everyone,

Still doing our mock inspections, any clue why the receptacle looks like this and what it is used for, found it in a house built in 1925, in the living room.

Never seen that one, looking forward to the answer.

Parallel and tandem socket, it’s obsolete and will most likely not have a ground.

I will look for some pics.

They are obsolete 120-240- volt receptacles. Recommend replacement by qualified electrician.

Found it and here is the power of google as well :wink:


Yep parallel was the 120 and the tandems were the 240. :wink:

While we’re at it this is an obsolete telephone jack that you may come across in older homes.
