Which of the following is NOT a voltage type found on the RB-M 45?

The 45-Foot Response Boat-Medium (RB-M 45) operates with specific voltage types that cater to its electrical systems. The boat is equipped with various components that require different voltage levels for optimal performance.

In this context, 12 volt and 120 volt systems are commonly used in marine applications for auxiliary power and standard electrical systems, respectively. The presence of a 240 volt system can also be typical for larger electrical equipment, particularly in shore power connections or some specialized systems.

However, a 30 volt electrical system is not standard for the RB-M 45. Marine vessels typically do not utilize a 30 volt system, making this voltage type an outlier. Therefore, recognizing the types of voltage levels that are employed is crucial for understanding the electrical architecture of the RB-M 45.
