I think, it does not need a UAT breaker since if the UAT
does not supply power to the generator auxiliary the
generator will shut down, any way. So, the generator
breaker will protect the UAT also. Providing a UAT breaker-
not taking into consideration the expenses-it could be an
other generator failure point if this breaker would fail or
would open unmotivated.
