Ah, there is only one neutral, I thought you were bring the neutral from the generator, too. And it's not even being used, correct?
If the neutral is not used, the neutral terminal should either be grounded at the transformer or floated with no lugs whatsoever; no sense wasting copper running a white wire to nowhere.
If it's already in place, color it green and call it a ground
If there's no neutral current and you're just running it from a grounded T0 to the ground bar in the transfer switch, it's not a neutral,
