Normally, from which source is the No.2 inverter powered?

• A. RH load bus
• B. Emergency bus
• C. Start bus
• D. Battery

Answer: (A)

The No.2 inverter is designed to feed the right-hand electrical distribution, so in normal operation its input comes from the right-hand load bus. This keeps the right-side ac power tied to the same source that powers the RH loads, ensuring proper distribution and isolation from other systems. The emergency bus is reserved for essential systems only in abnormal conditions, the start bus handles engine starting circuits, and the battery provides DC power (or back-up) rather than the normal source for this inverter.
