W-B As usual when there's an electrical question everybody and their brother in law (Including me) crawls out of the woodwork and there are tons of opinions (some right some may get you killed) moreso then on most other topics. I enjoy and appreciate them all, the more the merrier, all a great bunch of gents here who like to help as do I, GOD BLESS THEM ALL
HERES THE REAL DEAL
1) When it comes to Life Safety and risking your life, its your free choice to believe
a) The NEC or the OSHA experts, or trained experienced professional electricians and engineers OR b) A non electrician or non engineer or non electrical technician or Billy Bob and Bubba who wired their own home while downing a case of beer and its "always worked" and by golly they are experts and are right and smarter then the NEC and OSHA
2) Unless trained and experienced and an electrical professional or the NEC or OSHA electrical experts, many (NOT all) DO NOT UNDERSTAND AT ALL ORRRRRRRRR the difference between NEUTRAL GROUND BONDING and NEUTRAL GROUNDING and the concept of SINGLE POINT GROUNDING and what's a safe and proper GROUNDING ELECTRODE and what constitutes a safe and proper EQUIPMENT GROUNDING CONDUCTOR
3) Some non electricians or non engineers or Billy Bob may say "The Owners Manual says to "Ground" your Generator HOWEVER they do NOT a) Read where it may go on to say GROUND PER THE NEC and they do NOT b) Understand it makes a difference if the Generator is wired and configured as a "Separately Derived Source, nor c) If the Generator has a FLOATING NEUTRAL or not or d) If the generator feeds a home via a transfer switch or if it serves ONLY plug and cord connected tools plugged into onboard receptacles like some construction site generators
4) The NEC and OSHA (see URL Link below) instructs there are times when you do "Ground" your portable generators BUT TIMES YOU DO NOT AND IF YOU DO ITS HAZARDOUS !!!!!!!!!!!!!!!!!! For example when where and why its HAZARDOUS see the URL link below
5) Some small Generators come from the factory WITH A FLOATING NEUTRAL while some come form the factory WITH A BONDED NEUTRAL and they are treated and configured differently
6) It makes a difference if the generator feeds a home via a transfer switch or is a construction site generator
7) It makes a difference as to how many POLES the Transfer switch has IE is the Neutral switched or not??????????
AND THERES LOT MORE DIFFERENCES AND WHEN AND WHEN NOT AND HOW AND WHERE A GENERATOR IS GROUNDED
SEE THE OSHA URL LINK BELOW THAT EXPLAINS HOW IMPROPER GROUNDING A CONSTRUCTION SITE GENERATOR IS A HAZARD
CLOSING,,,,,,,,,,DO NOT TAKE MY WORD FOR IT, CONSULT THE NEC AND OSHA, ITS THEM NOT ME THAT SAYS THIS
If you want to flame on someone and you're right and the NEC and OSHA is wrong TAKE IT UP WITH THEM NOT ME I'm only the messenger who is trying to save someones life, if that makes me a bad person call me bad
There are times when proper grounding is right and safe, and times when if done wrong IT CAN GET YOU KILLED it all depends on many many of the factors above which are all impossible to explain here.
Its your choice and your life at risk, so do it like your brother in law says or do it like NEC and OSHA says FINE BY ME and tell the NEC why your are right not them , I'm just trying to help and save a life NOT argue with yall HOWEVER having been trained and experienced in electrical safety over a forty year career who has attended NEC updates and seminars and who understands it IF I HAD MY CHOICE ID TRUST THE NEC OVER ANYONE HERE (me included lol) so flame on and argue with them if it makes you feel good and show how you're right and they are wrong, that will be a fun read lol but I will keep an open mind and maybe learn something, never too old to learn
John T Long retired and rusty Electrical Power Distribution Design Engineer SO NO WARRANTY consult the NEC NOT meeeeeeeeeee don't do as I say do what the experts orrrrrrrrrrrr Billy Bob says, its your life and your choice

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
