So a ordinary 3AG fuseholder https://www.amazon.com/FUSEHOLDER-B...id=1503376929&sr=8-1&keywords=3ag+fuse+holder will be legal err compliant? That's my kind of easy.

Probably. But you should also probably calculate the available fault current from the generator (low compared to service) and then look at the AIC rating of the fuse and holder.
Most xfer switches have
user available control power present before xfer
a set of contacts that operate prior to xfer
an adjustable delay before xfer
no need to reinvent the wheel
cobbling something together that is not listed by modifying a listed device may not be a good idea

ATS Pre-Signal Feature
ATS Pre-Signal Feature
See attached thread that I wrote in response to another post on this forum. The title states elevator presignal but it functions the same as any load disconnect, motor disconnect, etc. As Ingenieur has stated many times here this feature has been offered by almost all ATS manufacturers in the commercial and industrial markets, whether old or new; not sure of the residential units.
I have designed and installed control schemes for older ATS's that provide dry contacts to disconnect various types of loads prior to transfer then reset after transfer. This may be required in your case if this feature is not provided or supported by the ATS manufacturer.
