Thanks for the reply.

The generator will be for powering the house. The house panel will be
back-fed through a 240V breaker with a mechanical interlock preventing the
backfeed breaker and the main breaker from being turned on at the same
time.

I am not sure what you mean by "bonded".

On some generators the neutral is connected to the ground (bonded). On most
it is not. (non-bonded). It should say on both the generator and manual.

If you have a unbonded generator you are all set. Your generator is
grounded through the breaker box, and must not be grounded independently;
the ground loop you referred to.

If you have a bonded generator you have a problem. The generator must be
grounded, and the neutral connection on your main feed must be switched
along with the hots; again to prevent loops.

I don't have it saved any more, but there is a wonderful website from a
Canadian distributor that explains all of this in extreme detail with
diagrams; but I gave you the heart of it.
