NOT switching the neutral
NOT switching the neutral
(OP)
I have a 3000A grounded wye service with main breaker, GFP and 3 pole ATS. The generator neutral and ground are not bonded together and are tied to the respective buses of the swithcboard. Is this a code violation?

The generator breaker can also have GFP.
If your local 480 V main breaker trips, you should not be trying to re-energize from the generator, since you could be closing in to a bus fault. You need sense loss of utility voltage ahead of the main breaker.

If the two neutrals are not interconnected (may be because the load does not need a neutral) then you must ground the generator neutral at the generator end.
