what about those switches they sell at Lowes and Menards that you wire in to
your house where you   have 1 side of the switch  for genset and  then the
middle  is off and then the other side is for comerical.. That is no more
than a Breaker..

Why wouldn't the main breaker  work as s disconnect point.? The grounds are
still common wheather you use a double poll double throw or not?
