I would be curious just exactly how much capacitive coupling there really is but since small Honda generators are shipped without a bonded neutral and we have not seen dead bodies dropping all over I doubt it is a problem.
Again, if nothing is grounded, where is the fault path?
I imagine the EGC would measure 60v to each phase and zero to a water pipe. A megohm resistor to either phase would make the 60v go away.
