Power Distribution - Alternator 1 Only
31 July 2001
Figure 91-103 depicts the system loading during operation with only alternator 1 generating at nominal val-
ues, such as low RPM operation, or a failure of alternator 2. Note the diode between the Main Distribution
Bus and the Essential Distribution Bus is forward biased and therefore is conducting current between bus-
ses. All circuit breakers and fuses are of adequate capacity when the circuit breaker rating is greater than
the total load value. All circuit breakers and fuses are of adequate capacity.
