Which of the following statements about switching between AC power sources is True?

Switching between AC power sources is a critical process in electrical systems, especially in marine applications where reliability and safety are paramount. The correct answer indicates that both statements provided in the question are true, suggesting that they accurately represent important aspects of this switching process.

When switching AC power sources, it's essential to ensure that the voltage and frequency of both sources are compatible to prevent equipment damage or operational issues. Devices like transfer switches or automatic transfer switches (ATS) are often used to facilitate a seamless transition between sources while maintaining the integrity of the electrical system.

Additionally, proper safety precautions must be followed during the switching process to prevent short circuits or overloads. The statements likely address these principles, highlighting the importance of careful management of AC power sources.

When both statements in the question align with established practices and safety protocols, it solidifies the understanding that ensuring compatibility and following standard operational procedures is crucial when switching between AC power sources.
