Which of the following is true when installing grounding conductors used for lightning protection?

• A. Sharp bends must be avoided
• B. Ground conductors should be twisted
• C. Connections must be loose
• D. Only one grounding conductor is needed

Answer: (A)

Sharp bends must be avoided when installing grounding conductors used for lightning protection because such bends can increase the resistance of the grounding system, which reduces its effectiveness. A grounding conductor that is straight and has minimal bends provides a better path for the electrical discharge from lightning to follow safely into the ground. This helps to ensure that the energy is dissipated quickly and efficiently, minimizing the risk of damage to equipment and structures. Additionally, the integrity of the grounding system is crucial for protecting against electrical surges, and a smooth, unobstructed path is vital for maintaining low resistance and proper function during a lightning strike.
