Mark the discussion was mainly about PORTABLE generators... (with wheels)
The discrepincies are, with a two pole transfer switch everyone seems to concur that you need to remove the neutral bond in the Gen. If that is done is the Gen still safe for stand alone use without the neutral bond that was factory installed and UL approved.
In the USA most if not all transfer switches are sold as only two pole units... (Canada sells 3-Pole, as is really needed)
The hesitation was in changeing factory wiring on a Gen and it's then safety factor... (and the Bonding jumper size was a side point)
