- bus bars,
- "pull-off" type circuit-breakers of PL1 circuit-breaker panel,
- circuit-breakers of PL1 circuit-breaker panel,
- switch-breakers of PL2 central pedestal.

3. DESCRIPTION (Figures 2 and 3)
A. Fuses
Fuses inserted in PL3 panel located on firewall door 212L protect the systems which are not protected by circuit-breakers.
NOTE : The diagram located on PL3 fuse panel allows localization of fuses. Spare fuses are located on the cover fixed on door 212L.
The advisory panel, tachometer, control and landing gear control panel and engine monitoring cluster are supplied by the "BUS 1" bar. If this bus is lost or manually shed, the "BUS 3" bar automatically supplies these instruments through a relay located in PL3 fuse panel.
B. Bus bars
Bus bars are the elements which dispatch DC to the various circuits. They are located behind PL1 circuit-breaker panel.
C. "Pull-off" type circuit-breakers
In addition to protection of the alternator supply with a 60-amp "pull-off" type circuit-breaker labeled "ALT", the following "pull-off" type circuit-breakers have been installed :
