I have installed several sub-panels in our electrical system (Square D).
Most of these sub-panels come with a screw/bolt which connects the ground bar and neutral bar in the sub-panel itself. (In the case where the panel is used as a main). When used as a sub-panel this screw/bolt must be removed. (Un-bonding). The sub-panel and its circuits are protected by the bonded neutral and ground in the main service panel to which it is connected.
This was my thinking when applying the same principal to the generator. If all the conductors were separated at the generator, (120V, 120V, Neutral, Ground), and connected to the main system, even though the generator was supplying the power, it would still be protected by the main service panel just as would happen with a sub-panel.
Just thinking......

It will take a while for me to figure out what appears to be a contradiction. To use your description, if you unbound the sub panel, i.e., disconnect the neutral from the ground bus what about all your house appliances that are fed from the sub panel? Most appliances have the white wire and the bare copper wire connected to the neutral and the ground bus. I am not sure how you are going to provide a safety ground to the generator?

One minute you say unbonding the neutral from the ground and next you say it’s circuits are protected by the bonded neutral and ground in the main panel? I do not understand what principle you are trying to convey?

There has to be a common earth ground and only one, for all circuits regardless of using a sub panel.

Okay, one last time from my perspective. I can only describe how our wiring is set up.
Each sub-panel is simply an extension of the main service panel.
The sub-panel has 4 conductors which are directly connected to the main service panel.
Ground, Neutral, and 2 black (hot) conductors.
There is a continuous unbroken connection from each of these conductors to the main panel.

The circuits from the sub-panel are protected by the neutral bond in the service panel.
All I can say is that our wiring has been inspected and approved by a government inspector.
I still enjoy all the comments,
Thanks, Iver

Sounds right to me.

Over that sounds right to me also.

I bought a big ass Magnifying glass and discovered a whole world of things I could not see before.

Arthur Conan Doyle would be proud.

I used it yesterday when reconfiguring 220 to 110 on my antique table saw.

After 50 years of aging the "T" 1....8 were well worn.

Also, I found that on amazon, panduit sells special wire labels that you can run through your printer, waterproof abrasion resistant and only $5.00 for 90
