Generator bonding

[JoeNorm]

Meter and first means and disconnect at the street, so main panel in the house has floating neutral.

If I want to supply the main panel with a generator and interlock how do I bond the generator? Four wire feed with G_N bond at unit?

thanks

Neutral not bonded at the generator, EGC connected to the generator.

So when I switch the interlock and run the Gen there would be no neutral-ground bond anywhere?

Your bond would be at the main service panel or disconnect w/ocpd.

Unless you do neutral switching, nothing having to do with bonding will change when you operate a transfer switch.

With a remote main like described here, I am going to install the generator as a separately derived system and use a transfer switch that switches the neutral. Generators have a very hard time supplying enough current to operate in the instantaneous trip range of the OCPD, the the extra length in the fault clearing path if the generator is a non-separately derived system makes that issue worse.
