Can a grounding electrode used for lightning protection also serve as a grounding system for buildings?

The grounding electrode for lightning protection and the grounding system for buildings serve different functions and are designed to address distinct safety concerns. A grounding electrode for lightning protection is specifically intended to safely dissipate the electrical energy from a lightning strike into the ground. This is crucial for protecting the structure from the significant electrical surges associated with a lightning event.

On the other hand, the grounding system for buildings is typically designed to provide a path to ground for electrical faults and enhance the overall safety of the electrical system. This includes protecting against accidental electrical shocks and ensuring the proper operation of surge protectors and other electrical equipment.

While both systems are related to grounding and safety, they have specific designs and operational requirements. Therefore, it is not advisable to use one system interchangeably for the other, as each is tailored to meet its unique set of safety standards and performance criteria.
