I have an outbuilding that houses my pool and sprinkler pumps. There is a rod outside the building, driven into the earth. At the top, I found what appears to be a 10-gauge wire, disconnected. I guess someone knocked it loose, or it corroded. I assume the rod is the ground for the building. My feeling is that it should be connected, in order to prevent things like death.
What's the correct way to attach the wire to the rod?
