I will be starting a project soon. My old code books are long gone. I will check out what Lowes has probably next week and try to give my opinion on what I get to help me with current code and report back. Remember those books are somewhat generic and not necessarily in tune with local inspector interpretations. Mine is a generator. There is more than one opinion on such a system called "a separately derived system" about earth grounding of the generator. That has changed over the years. Stand alone portable generators used in the field are another subject covered under the OSHA Safety codes; used for building emergency power is the NEC.
LOL, Ron
Some differences if your generator floats it’s neutral or if the generator’s neutral is bonded to the generator’s frame and receptacle ground prongs.
