dfe take the generator and the ATS out of the picture.

Now put the same fault on a circuit.

The result is the same, removing the bonding jumper or neutral at the service will be dangerous.

By using a Neutral switching ATS switch all that will be accomplished is moving this potential problem from the normal power bonding jumper to the bonding jumper that will be installed at the generator.

I see one location as safe / dangerous as the other. [Linked Image]
