We are installing a single phase 600 ATS 75 feet from the service. We are installing 4 sets of 350 mcm copper in 4 each 3 inch pvc conduits (Line - Load . With respect to grounding, am I required to install (250.66) 1 each 2/0 Grounding Conductor in each run or will 1 grounding conductor (Size?) bonding the generator and switch be legal? Should this be handled as an appliance or an AC system?
Thank you
