Default How the heck does a typical home transfer switch work?

Essentially they are probably 2 100a panels fed by a 200a service.

What amp service do most people have?

I just put some chalk on the raised letters of my mains circuit breaker
which showed the mains breaker to be 200 Amps (not 300 Amps as I stated
prior).

There are three separate 100 Amp breakers, each going to a different panel.

So I think, at this point, that the reason for the TWO 100A Generac model
79848A transfer switches

is simply that each one handles 100 amps nominally.

Now I just need to figure out how to debug why this two-fisted solenoid
isn't switching on automatically - but it does switch on when I flip it
manually.
