Final answer:
An ESS is a component of an overall physical protection system, providing safety measures for electrical equipment.
Step-by-step explanation:
The statement that an ESS is a component of an overall physical protection system is true. An ESS, or an Equipment Safety System, is designed to ensure the safety of electrical equipment and prevent accidents. It is typically installed as part of a larger physical protection system to provide protection against various risks, such as electrical shocks or fires.
For example, in the case of a building, an ESS may include various components such as circuit breakers, ground fault interrupters, surge protectors, and emergency power systems. These components work together to detect and mitigate potential electrical hazards, ensuring the safety of the occupants and the equipment.
Therefore, an ESS is indeed an important component of an overall physical protection system.
