My local inspector is telling me that the phone and cable TV lines have to be bonded to ground. How is this accomplished? Do I bond to the casing of the cable splitter? How about the phone? Which one of the wires is ground?
Normally, the cable and phone are bonded to the grounding electrode conductor between the service entrance and the ground rod. There should be a grounding block or splitter on the cable with an attachment point for a ground wire, either 12 or 10ga copper. The telephone interface box (NID) should also have a ground attachment, usually connected by the local phone company when installed.
