i have a bunch of outdoors 2' x 4' open bottom concrete junction boxes. the question is, does each box need to have a ground rod installed and bonded to the ground wire? if so can someone please point me in the right direction in the NEC code book?


If these are just junction boxes you don't need a ground rod. Why do you think you need a rod? If a transformer vault or the base of a power pedestal that would be a different answer. Grounding electrodes are covered starting in 250.50.
