In flight, with only one engine generator operating, how is the electrical system configured?

The correct answer highlights that when only one engine generator is operational, the main galley power supply is automatically shed to prioritize the electrical load on the aircraft. In this situation, the aircraft's electrical management system must ensure that essential systems remain functional while reducing demand on the single available generator.

Under normal conditions, both engine generators supply power to various electrical buses, but if only one is working, there is a need to limit non-essential loads. Shedding the main galley power, which typically has a higher electrical demand, helps preserve power for more critical systems like flight instruments, navigation, and control systems that are vital for safe operation of the aircraft.

This operation aligns with the aircraft's design to enhance safety and reliability in situations where power supply is compromised.
