Thanks,
I see the DC GND/FLT supply from TR2 but the list of loads that can be energized does not include LGCIU1. Do you have a reference I can follow up?
I see LGCIU1 is available in EMER ELEC so that seems logical that DC ESS Is powering it via ESS TR when TR2 is not available. I cannot find any description of this in the FCOM though. Very frustrating.
Can anyone post a list of kit powered by the DC FLT BUS, I’m interested to know how a DC FLT BUS Fault would present itself on ECAM because it sounds like a minefield to diagnose.
