EXTERNAL AC SYSTEM
AC external power is supplied through a stan-
dard six-pin AC power receptacle located on
the right-hand nose section of the fuselage
(Figure 2-7). An external power monitor en-
sures that the external AC power is safe and
within specified limits before power is ap-
plied to the airplane buses (Figure 2-8). If the
parameters of phase rotation, frequency (400
± 25 Hz), and voltage (115 ± 9 VAC) are sat-
isfactory, the monitor causes a green AVAIL
light to illuminate on the electrical power sec-
tion of the overhead panel. Provided no other
airplane generator is on line, movement of the
G PWR switch to the ON position extinguishes
the AVAIL light and illuminates the amber IN
USE light. This indicates that external AC
power is now connected to the airplane buses.
If the APU generator or any main generator is
brought on line, external power automatically
reverts to an available status.
