My 1950's-ish home in Pennsylvania has an addition built off of the kitchen (no idea when the addition was built). In this addition there is a closet I am remodeling. While taking down the wood paneling I found this:
My first thought was that it could be a doorbell chime since this addition has a door to outside, but then I remembered that door has no bell. It definitely has power running to it. What is it and how do I remove it? My idea at the moment is to shut off the main breaker (since I don't know which one this is on), unscrew the wires, put in a box, cap wires, and when I drywall put a plate over it for later access if needed.
