During normal operation, Battery 1 is connected in parallel with which generators?

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

Answer: (B)

Battery 1 is connected to the same DC bus as the two generators on the left-hand bank, generators 1 and 3. In normal operation the electrical system is designed with two generator banks that feed the main DC buses, and each bank is paralleling with its corresponding battery. This setup allows Battery 1 to share current with Gen 1 and Gen 3, helping maintain voltage, enable charging through the same path, and provide smooth power transfer if one generator trips. The other bank—generators 2 and 4—pairs with Battery 2, so Battery 1 isn’t paralleled with them during normal operation.
