When the incoming service entrance conductors pass through a j.box on the extreior of a building and then nipple through the wall to the main overcurrent protection device.
If a rigid nipple is used, what are the bonding / grounding requirements?
Also, the j. box is metal and the service entrance conduits from the utility transformer is pvc.
