Overhead service grounding
We were told to ground our overhead service, but the tech left before explaining what needed to be done. Our overhead service runs over the street, attaches to one side of the house and then runs exposed to the other under the eaves where we have a Nema 3 box that Cox will connect to either our coax or fiber. Do we need to ground the box to the nearest conduit? What size ground is required? Do we need bare copper? Any help is appreciated.
