Which of the following is true about grounding as a protective measure?

Grounding is considered a secondary measure in electrical safety, functioning to provide a path for excess electrical current to safely dissipate into the earth, thus reducing the risk of electric shock and equipment damage. While grounding is a critical safety practice, it is not the sole method of protection against electrical hazards. Other safety measures, such as circuit breakers, insulation, and personal protective equipment, play vital roles in an overall safety strategy. By employing grounding in conjunction with these other precautions, a more comprehensive approach to safety is achieved.

It's also important to recognize that grounding does not guarantee safety under all conditions, as environmental factors and system designs can impact its effectiveness. Additionally, grounding is not to be disregarded or considered unnecessary, as it plays a significant role in the safety and reliability of electrical systems.
