Default Article 702.7(C) Power Inlet (Signs for Optional Standby Systems)

Is a portable generator (the type typically used by home owners when the power goes out) a separately derived system? Or, is it considered a nonseparately derived system? I have thought it was a separately derived system, but now I am unsure. - When the generator is plugged in, I would say there is a solid connection between the grounded (neutral) conductors. Wondering which sign listed in Article 702.7(C) needs to go by the generator inlet.

Most portables have a neutral/ground bond, some don't. The ones with a neutral/ground bond SDS, not bonded nonSDS. Whether you switch the neutral or not with a neutral bonded generator or not is another story.
