[RE-wrenches] pull box in solar raceway

With certain designs where you have the service between the array and the inverter, you may be compelled to make a common raceway to a pull box and divert a conduit to the service from there. The conduit between the pull box and the inverter would then have your ac wires and dc wires running to the inverter and branching at the pull box.

Would the GFDI still operate properly if you bond your system ground from the inverter with the equipment ground from the array in the pull box, or would that pathway to the grounding system in the service from the roof not allow the inverter to detect a ground fault properly?


If there is a difference to the inverter, how would bonding the raceways affect the ground path? (If you are bonded at all fittings roof to the inverter, then the conduit from pull box to grounding system would be a path that could also circumvent the inverter.)
