What does NFPA 780-2017 pertain to regarding electrical systems?

The National Fire Protection Association (NFPA) 780-2017 specifically addresses the standards for the installation of lightning protection systems. This standard provides guidelines on how to implement grounding and bonding practices that are essential for protecting structures and electrical systems from lightning strikes. Proper grounding and bonding reduce the risk of fire and electrical shock due to lightning. This standard includes recommendations on materials, design principles, and installation techniques, thereby ensuring that electrical systems are effectively shielded from the hazards associated with lightning. By following these guidelines, electricians and engineers can help ensure safety and mitigate potential damage from lightning events.

The other choices do not relate directly to NFPA 780-2017, which specifically concentrates on lightning protection rather than solar panel installation, energy-efficient materials, or general electrical circuit design.
