3. Operation/Control and Indicating
The main busbars can be supplied:
A 115/26 VAC single-phase autotransformer supplying a normal 26 VAC/400 Hz sub-busbar (131XP.A and 231XP.A) is connected to each main busbar.
Part of the AC main network (212XP, 214XP, 216XP.C) can be supplied directly by the ground power unit in ground service configuration (Ref. 24-42-00, P. Block 1). For each main busbar, a warning is triggered on the ECAM to indicate a loss of supply
The main busbars can be supplied:
- either by the corresponding generator,
- or by the other main generator, or by the APU generator or the ground power unit by means of the transfer circuit.
