I've got a question about Airbus A320 electrial system
If i press both p/b of the generator to the OFF position , AC BUS 1 and 2 will be no more powered.
The question is: Will the RAT deploy automatically or not in this case?

A clear explanation will be appreciated!

Short answer: Yes, the RAT will deploy.

The automatic deployment requires three conditions to be met: AC BUS 1 OFF, AC BUS 2 OFF, ADIRS 1 > 100KT
All fulfilled, the RAT will deploy. As a signal on airspeed is required, it can't happen on ground.
Manual extension is NEVER inhibited, it can be initiated at any time. Thats why the buttons are guarded.
