Have a facility in the middle of nowhere, literally, fed by genset only. Two 600kW gensets in an N+1 setup, only run one at a time. Each genset connects to a manual transfer switch with a single feeder to an MDP. Run one genset one period, manually shift, run second set the next period. My thoughts were bonding grounded to grounding in the MDP, with EGC run back to each genset, ensuring there is no N-G connection in either genset, and calling it a day. Each genset has an output CB. What am I missing? This would require 4P transfer switch to isolate neutral in offline genset
