Which of the following is regarded as a best practice for handling 3-phase shore power?

Monitoring phase rotation is crucial when dealing with 3-phase shore power because it ensures that the electrical systems are connected correctly to maintain proper operation and avoid potential damage to equipment. In a 3-phase system, the rotation of the phases is essential for devices that rely on phase sequence, such as motors. Incorrect phase rotation can lead to motors running in reverse or not functioning at all, which can cause mechanical failure or safety hazards.

When the phase rotation is monitored correctly, it allows for proper connections and optimizes the performance of the electrical systems. This practice enhances safety by minimizing the risk of short circuits or overloads caused by incorrect phase alignment. Hence, the emphasis on monitoring phase rotation reflects its importance in maintaining the reliability and efficiency of a 3-phase electrical system.
