Where I work to keep noise down on our communications circuits we always have #2 green on isolated ground buss and bond neutral to ground in the meter panel only. On my meter panel at the house there is no ground (just neutral), and on my neutral/ground bus (in breaker box)my ground wire is a 10 or 12 gauge solid going to my water pipes. Should I do anything to the existing setup? Or is it safe and good? Thanks alot, your advice is really helpful! Really.
