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

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.
