NOTE
A maximum of 3 buses only can be
manually isolated concurrently.
AC BUS FEED SYSTEM
Each AC bus is normally powered by its own generator through generator line contactors. In the event of a generator malfunction, the priority system will automatically provide an alternate generator (feed), to power that bus (APU must be started to be available to the feed system), through generator transfer contactors.
The AC busses are normally powered by their own generator, but can be powered by alternate generators in the following descending order:
.
AC BUS 1 . GEN 1, GEN 4, GEN 3, GEN 2, APU GEN.
.
AC BUS 2 . GEN 2, GEN 3, GEN 4, APU GEN.
.
AC BUS 3 . GEN 3, GEN 2, GEN 1, APU GEN.
.
AC BUS 4 . GEN 4, GEN 1, GEN 2, GEN 3, APU GEN.
