During normal operation, Battery 2 is connected in parallel with which generators?

• A. #1 and #3
• B. #2 and #4
• C. #1 and #4
• D. #3 and #4

Answer: (B)

In normal operation the right-hand DC bus is powered by a pair of engine-driven generators, and Battery 2 is tied into that same bus so it sits in parallel with those generators. This parallel connection lets Battery 2 share load on the right-hand bus and provide immediate current if one generator dips or a transient occurs, helping keep the right-side power stable for essential systems. The left-side power is handled by the other generator set and Battery 1, so Battery 2 isn’t in parallel with those.
