1. INTRODUCTION
The aircraft uses both 115 Volts AC and 28 volts DC power. AC electrical power is provided
by two engine-driven generation systems. Each system includes an integrated drive
generator (IDG) and a generator control unit (GCU). An auxiliary power unit (APU)
generator is also available as a back AC power source to replace either or both IDGs.
In the event of total AC power loss, emergency AC power is available from an in-flight
air-driven generator (ADG). The ADG assembly is stowed in a compartment on the right
side of the nose section.
DC power is supplied by five transformer rectifier units (TRU) which rectifies AC input power
into DC output power. Another source of DC power is from a main battery and APU battery.
The main and APU batteries are connected into the aircraft DC electrical power system and
are charged by their respective battery chargers. Power for starting the APU is provided by
the APU battery.
Electrical contactors, switches and relays located throughout 13 junction boxes in the
aircraft, are used for connecting AC and DC power to the appropriate buses and
components. Power connection is dependent on system configuration and health. The
following is a list of all the aircraft electrical system buses:

On the ground, the aircraft can receive external AC power through a receptacle located on
the forward right side of the fuselage. The aircraft can also receive external DC through a
receptacle located on the aft right side of the fuselage.
The electrical power services panel (EPSP) in the flight compartment, and the external
service panel on the right forward fuselage, contain the AC and DC system control switches.
The switches are used for manual and automatic control of the electrical power generating
