BACKFEEDING the Utility, which can be a hazard to utility workers (but hey they are well aware of and protect themselves), occurs when a genset gets accidentally connected to the incoming Utility wiring. Just as the transformer drops say 9600 volts down to 120/240, if you backfeed a gensets 120/240, the transformer steps that up to say 9600 volts YIKES !!!!!!!!!!

Neutral Ground Bonding, Floating versus Bonded Neutrals, Earth Grounding of the Neutral, Separate Derived Sources, Transfer switch methods (including if Neutral is switched or not ?) and safe proper gensest use and switching IS NOT EASILY UNDERSTANDABLE even to trained professional electricians and engineers, so its easy to see why there is confusion in the lay community. Typically professional electricians and engineers who are trained in and practice using the NEC daily have a different opinion regarding it then lay persons, that's to be expected and should come as no surprise whatsoever. That's the same in Plumbing and Building Codes and other professions, those deep long winded code books are hard to comprehend grrrrrrrrrrrrrr lol.

Having practiced in different jurisdictions I agree different communities may or may not have even adopted any particular code versions or any at all and that can be confusing even to the electricians let alone a homeowner.

If there are doubts which may be a hazard to your life or cause a fire my professional advice is to consult a trained competent professional electrician and engineer NOT your know it all brother in laws Billy Bob or Bubba who wired their garage while downing a case of beer and by golly it works fine. Its your home, your life and your own risk and I support any persons right to choose what they do in their own home, I sure did in mine.

Yall be safe best wishes n God Bless
