I saw a failed transfer switch cause 480 to hit 480 once at a job and all that was left of the surge protector was a black spot on the wall

That could have happened to mine when I used to hook my well pump pressure switch to my generator, because it was still wired to the house as well (IIRC). I guess I would turn the main breaker off at the panel. But when professionals install back-up generators they are set up to isolate from the breaker panel.
