Power Distribution - Normal System Operation
31 July 2001
Figure 91-102 depicts the system loading during normal system operation with alternator 1 and alternator
2 generating at nominal values. Note the diode between the Main Distribution Bus and the Essential Distri-
bution Bus is reverse biased and therefore is not conducting current between busses. 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.
