A320 FCOM Electrical Supply interpretation

Hi guys,

On my FCOM, in each section of systems, there is an Electrical Supply section. In this section it lists what powers what. Example: FCOM DCS-29-40 Hydraulics ENG 1 driven Pump control = DC1, in the Norm/DC/ Column. So DC bus 1 powers that and if we lose DC bus 1, we lose that pump control.

So far, so good.

However, in another example DSC-32-10-60 Gears and Doors. It says for LGCIU 1 GRND/FLT on the Norm/DC/ Column.

Maybe it's a stupid question but... what does GRND/FLT mean exactly? And where exactly does the power come from?

I hope my question is clear.
