Thanks for that referrence, Ron. I looked it up in my handbook, and guess what? There, in black & white as well as diagrams, was just this setup, looking at it two different ways !!!!
Remove the bonding jumper at the genset, and use a 3-pole ATS, and you don't have a seperately derived system. Removal of the jumper may void the manufacturer's warrenty. Check with them first.
If it is required to be there, then does this mean you have a seperately derived sytem? Actually, this has little do do with the classification.
It only depends on if the grounded conductor is switched in the ATS or not. 3-pole, not a SD sytem, if a 4-pole, is a SD system, and all rules applying to such must be followed.
Now I'm not sure what to do with the bonding jumper, if installed on the genset.
Thoughts?
