Standby System and Bonding

[Bogiedown170]

Just came across an area that is designated as a flood zone. The generator is bolted to a metal stand that is about 3ft tall on concrete base. As I’m trying to get up to speed with 2020 code, I was wondering if it is necessary for the generator to be bonded to the metal frame? Under normal installation, I understand that no grounding rod is necessary, but with the metal frame, is bonding to frame required and or ground rod? Thanks to provide any insight.

As long as it’s wired as a NON-separately derived system I don’t see where ground rods would be required . As well as bonding the generator chassis to the metal stand I believe that would be a good idea.
(Just my two cents) well see what others have to say.

Now there's a generator that would almost be a pleasure to service.

I think that this is basically correct, especially as I've edited it. I believe the metal stand should be bonded to the supply side bonding jumper that's brought to the generator.
