What's "floated" mean? Is the ground simply not connected to anything but the metal of the generator housing?
Craig. On a "floating neutral" generator the ground is only attached to the metal of the generator, and it is specifically design to operate not terminated to earth. Further, there is no neutral - ground bond point on these generators.
I wrote a detailed sidebar on the specific topic of floating neutral generators in an article for a major industry trade rag, I'm happy to send you the text of that sidebar via email if you PM me.
Cheers,
