I have a question about grounding a ground mount system. I have had a discussion with the engineer about grounding the supports for the pv system. The modules are bonded to the vertical rails in way of weebs, however, the vertical rails are not bonded to the horizonal supports, nor are they bonded to the ground supports. The engineer states that they are not in the path of the current and therefore do not have to be grounded. I showed him the 690 code on bonding all metal parts, but he said that's left to interpretation. In the following pictures, I have green circles where there are weebs, and red where there is not a bond. Also, on the picture of the inverter, they are wanting to carry the ground from the inverter, down the rack, and 6ft over to the building. Is this sufficient. Thanks in advance for any help. Please list any NEC code reference.
