After stowing the ADG, what is the next action to transfer power back to the primary bus?

• A. Press PWR TXFR OVERRIDE
• B. Reconnect the generator via the bus tie
• C. Reset the ADG again
• D. Turn on the standby battery

Answer: (A)

When the ADG has been stowed, the next step to put power back on the primary electrical bus is to use the Power Transfer Override. This control forces the system to retransfer power from the ADG back to the main generators and primary bus, reestablishing normal power distribution. The standby battery and other actions don’t accomplish this transfer to the primary bus, and resetting the ADG would simply affect deployment, not the transfer back to the main power source.
