I moved into my house about nine months ago, so I'm still discovering interesting new things.
I was doing some work under the kitchen sink, and I noticed a thick stranded copper wire coming up into the cabinet through the hole that the plastic drainpipe passes through. It looks like the same kind of wire that's used to ground an electrical panel -- several thick uninsulated copper wires twisted together -- but it's not connected to anything under the sink.
I went and looked at the electrical panel, and it looks like the other end of this wire goes into the panel on the top side. The bottom of the panel has a similar wire that runs outside the house and down into the ground.
So what's the wire doing under my kitchen sink?
