CHAPTER 7: ELECTRICAL Introduction
The Challenger 604 primarily uses 115-volt AC power and also 28-volt DC electrical
power.
Engine-driven integrated drive generators (IDGs) supply the primary source of AC
electrical power. A generator mounted on the Auxiliary Power Unit (APU) provides an
alternate source of AC electrical power. In flight, if a total loss of AC power occurs,
the air-driven generator (ADG) is deployed from the right side of the forward fuselage
to provide an emergency source of AC electrical power. External AC electrical power
is supplied through an electrical power receptacle located on the right side of the
forward fuselage.
Various aircraft systems and components require DC electrical power for operation.
DC electrical power needs are primarily supplied by four Transformer Rectifier Units
(TRU) mounted in the nose compartment. Two nickel-cadmium (NiCad) batteries,
located in the aft equipment bay, store and provide a source of DC electrical power for
normal and emergency operations.
The aircraft is capable of accepting 28-volt DC external electrical power through a DC
power receptacle installed on the rear fuselage below the right engine.
Five circuit breaker panels provide power distribution. Four circuit breaker panels are
located in the flight compartment and the fifth panel is in the aft equipment bay.
Control and operation are accomplished through the ELECTRICAL POWER Panel
located on the left side of the overhead panel. AC and DC electrical system
information is provided on the EICAS.

Alternating Current (AC) System
Description
Three AC generators provide AC power for the aircraft electrical systems. Two
engine-driven generators power all AC buses during normal operations. An APU
generator provides a source of AC electrical power when the aircraft is on the ground
with the engines off, and during flight if both engine-driven generators become
inoperative.
