Which of the following statements about grounding systems is false?

The statement that the grounding system must be dedicated solely to lightning protection is false. Grounding systems serve multiple purposes beyond just providing protection against lightning strikes. They are primarily designed to ensure electrical safety by directing fault currents safely into the ground, minimizing shock hazards, and enhancing the overall reliability of electrical systems. Grounding systems also help to stabilize voltage levels, reduce electrical noise, and mitigate the risks associated with electrical surges caused by lightning or other transient events. This multifunctionality of grounding systems is essential in both residential and commercial settings, allowing them to be utilized for various electrical safety and operational improvements rather than being limited to only lightning protection.
