I have installed a 200 amp service line down to a new meter base, then into a new 200 amp breaker box (upgrade from the 1956- 60 amp service that was there) . I have 2- 8 ' ground rods outside 6' apart , I have a continuous ground wire going to the fartherist grn rod from the nutral in the box. Do I run ground wire from rod to rod or do I run a 2nd wire from the same lug?
