Code Question of the Daytextbook

    Hello Code Question.

    Recently, a 200 amp service upgrade has taken place at a residence. The grounding electrode conductors are too short to reach the neutral bar but will make it to a listed and labeled auxiliary ground bar. The ground bar has been installed per the panel manufacturer’s installation instructions using the supplied hardware. The electrical contractor has connected a properly sized bonding jumper, in this case, #4 CU, from the neutral bar to the properly installed auxiliary ground bar. The green main bonding jumper screw is still in place. This creates a redundant main bonding jumper. Given this situation, is it permissible to connect Grounding Electrode Conductors to the auxiliary ground bar? Should the green screw remain in place, or should it be removed?
