I work at a facility that has miles of chain link fencing, and that fencing has ground rods with a GEC every 50'. Whenever new fencing is built we do the same thing. When I ask why are we grounding fencing that is already 2' in the ground the answer is always, "this is how we've always done it'. Do you have any insight or history on why fence grounding is necessary. Thanks for all your help.
