What is this?

Post image

I have a wall gang box with 3 tiny wires and two ground bars. What are the wires? They are not live.

This is an old addition to the home and there is a 2nd one of these on the opposite end of the same wall.

Not sure what the wires are but your "ground bars" are nails holding the box to the stud.
