Geeeeeeeee gang, I'm like Buick Man, dont know how many times we have to reinvent the wheel, theres just too many INCORRECT DEAD WRONG OPINIONS OUT THERE versus the electrical facts and safe proper methods. THATS ONLY MY PROFESSION ALBEIT RUSTY OPINION, NO WARRANTY
I have resolved myself to the fact THERES NO WAY REGARDLESS HOW HARD WE TRY to explain things in a few paragraphs that take volumes of books and years of training and experience AND THE BILLY BOBS OF THE WORLD ARE JUST NEVERRRRRRRRRR GONNA GET IT.. Although untrained and totally ignorant their way is right and by golly thats the ONLY way to do it regardless what professional and trained and experienced electricians and engineers and the stuffy NEC EXPERTS have to say GIVE ME A BREAK...
Okay, for the 100th time I will try to explain it: Sorry for the rant, I'm honestly trying to help and save a persons life here. THIS IS M Y OPINION and although I was trained and practiced AC Power Distribution an an electrical engineer much of my life I BEEN RETIRED TOO LONG AND AM RUSTY AS AN OLD NAIL grrrrrrrrrrrrr
Iffffffff you have a genset that is configured for 120/240 volt Single Phase Three Wire
Iffffffffff its NOTTTTTTTTTTT configured as seperately derived system
Iffffffffffff you only use a two pole transfer switch (i.e. you do NOT switch the Neutral)
1) Any of the gennys internal Neutral to case/frame bond should be removed 2) You would run 4 wires (Hot L1, Hot L2, Neutral, Equipment Ground) to a transfer switch 3) At the transfer switch (could be elsewhere) the utility Neutral and the Gennys Neutral WOULD BE CONNECTED 4) The main panels Equipment Ground would run out and bond to the gennys case/frame
Okay Billy Bob, if you insist on the use of plugs and receptacels and cords thats your own choice and business DO AS YOU PLEASE but pleaseeeeeeee dont have open exposed male plugs that can be energized,,,,,,,,please do not backfeed the utility lines which could kill a lineman,,,,,,,,please use a proper disconnect means or a transfer switch
Do as you please its your home and your risk DO NOT UNDER ANY CIRCUMSTANCES TAKE MY ADVICE OR DO AS I SUGGEST but you might want to consider the possibility that maybe just maybe a trained professional experienced electrician or an engineer or the panel of NEC experts or your local utility or inspection authority might just possibly might know more then anyone here (including myself) unkless they are trained professional experienced electricians or engineers.
So do as you please or do like someone here tells you but please for you or your familys life safety consider what the NEC suggests or what a professional suggests versus the untrained unprofessional Billy Bobs and Bubbas of the world might tell you.......
