For a portable generator trailered 480V generator where the neutral is not need for the load (not ran to transfer switch but is available at the genset), and the neutral IS bonded to ground at the generator, is this a separately derived system?
Based on the NEC definition of SDS, it sounds like it is because there is no direct connection from 1 system to another. It would be the same as if the neutral was switched at the transfer switch; neutrals are not connected.
