Question 398Electricity & Electronics - Assistant Engineer

The correct answer is C. The battery charger gets its AC power from the 120 VAC section of the emergency switchboard and is capable of providing DC charging current to only one battery bank at a given time. This is because the battery charger is typically designed to charge one battery bank at a time to ensure proper and balanced charging of the batteries. Charging both battery banks simultaneously could lead to imbalances in the charge levels, which could potentially harm the batteries. The other options are incorrect because they either state that the battery charger gets its power from the main switchboard (which is not typical for an emergency battery system) or that it can charge both battery banks simultaneously, which is not the standard configuration for a battery charger in a containership electrical system.
