OFF/RESET will disconnect the respective generator from the main AC buses. The OFF/RESET
position can also be used to reset the generator control circuit when a fault occurs.
Generator Control Unit
Each IDG is controlled and monitored by its respective generator control unit (GCU). The
GCUs provide protection and bus priority logic during normal and non-normal operations. The
engine generator is tripped off and removed from the AC buses if any of the following
conditions occur:
• Over- and undervoltage;
• Over- and underfrequency; or
• Generator and bus overcurrent.

APU Generator
The APU generator supplies 115-volt AC, 400-Hz, three-phase electrical power to the AC buses
during ground operations with the engines off. The APU generator may also be used in flight as
a backup power source to the AC buses following a failure of both engine generators. The APU
generator is mounted on the APU generator adapter, and is driven at a constant speed,
maintaining its frequency output at 400 Hz.
The APU generator is identified on the AC ELECTRICAL synoptic page by the symbol GEN
above the APU icon (see Figure 07−10−5). The nominal rating of the APU generator is 30 kVA
from sea level up to the APU’s maximum operating altitude of 20,000 feet MSL.

The two-position APU GEN switch, located on the ELECTRICAL POWER panel, controls the
APU generator. Selecting the APU GEN switch to ON connects the APU generator to the main
AC buses, providing it is operating normally. Selecting the switch to OFF/RESET disconnects
the APU generator from the main AC buses. The OFF/RESET position can also be used to
reset the generator control circuit when a fault occurs.
NOTE
Use of the APU generator in flight is permitted when one main
generator has failed or is off-line.
Generator Control Unit
The APU generator is controlled and monitored by the APU generator control unit (GCU). The
APU GCU, in conjunction with the engine GCUs, provide protection and bus priority logic
during normal and non-normal operations. The APU GENERATOR is tripped off and removed
from the AC buses if any of the following conditions occur:
• Over- and undervoltage;
• Over- and underfrequency; or
• Generator and bus overcurrent.

External AC Electrical Power
The aircraft is capable of being powered by an external AC power source when both engines
and APU are off. External AC electrical power is connected at an external AC receptacle,
located on the forward right side of the fuselage.

Operation
External AC ground power is controlled by the EXT POWER switch/light, located on the
ELECTRICAL POWER panel. When connected, the external AC ground power is checked by
an external power monitor for proper voltage, frequency, and phase. When the external power
is within limits, the green AVAIL annunciator on the EXT POWER switch/light illuminates.

When the EXT POWER switch/light is pressed with the AVAIL annunciator illuminated,
external AC electrical power is connected to the aircraft main AC buses via the auxiliary
power/external power contactor. The IN USE annunciator then illuminates.
External AC ground power is identified on the AC ELECTRICAL synoptic page by the symbol
EXT AC. This symbol appears only if external AC power is connected to the aircraft.
