Generator neutral should be tied to generator case and a ground rod unless
tied to a service entrance panel where they are tied together. Consult the
current NEC for more details.

Out of curiosity, how does the ground detection circuit work (and how
doe the 100k resistors trick it?)
[Also, if you instead drove a grounding rod into the ground and
connected it to the ground pin on your plug, would that work as well to
actually provide a ground? Or would neutral have to be involved?]
