24-50-00  AC ELECTRICAL – LOAD DISTRIBUTION Back

A. System Function

The ac electrical-load distribution system supplies the aircraft navigation systems from the two 26 V ac busbars on the avionics circuit-breaker panel. It also supplies the flight data system from the two 115 V ac busbars on the left circuit-breaker panel.

B. System Components

The primary components of the system are the:
  • Avionics circuit-breaker panel (Ref. Fig. 1 and Fig. 2)
  • Left circuit-breaker panel (Ref. Fig. 1 Fig. 3)
  • 26 V ac busbars
  • 115 V ac busbars
C. System Operation

The aircraft inverters supply 26 V ac and 115 V ac to the system busbars. The system busbars supply the navigation systems and the flight data system with 26 V ac and 115 V ac through the circuit breakers.
