I have a vague memory of this being discussed before, but I can't remember the details, nor can I find the discussion, so please bear with me.
Say I have a three phase inverter that does not require a neutral which is to be connected to the supply side of a service disconnect. Is there any reason to bring the neutral out to the fused AC disconnect and bond it to ground other than to bond neutral to the enclosure? It would be bonded to ground at that point, anyway, so the enclosure is bonded to ground through the GEC, and neutral is bonded to ground in the MDP or service disco, so voltage on the CCCs is already referenced to ground.
What would be the point of bringing neutral out to the disco? I seem to remember someone saying that it should be done, but I cannot remember why.
