How the heck does a typical home transfer switch work?

How about a real Gernerac model number? The part and assembly numbers
on the visible nameplates don't seem to point to a particular model.

I couldn't find a model number, so how about a search by serial
number?

Incidentally, you should consider labeling the cables, wires,
terminals, fuses, etc.

Why two transfer switches?

Got a schematic of how you wired it? If not, trace the wires and make
one.

I had no problem finding the Generac wiring diagram for one switch but
nothing for two. That is why I am asking if there are 2 emergency
panels.
The switch itself is a garden variety DPDT "non SDS" transfer switch.
