Should metal raceways of an electrical system be bonded or spaced from lightning protection conductors?

Metal raceways of an electrical system should be bonded to lightning protection conductors to ensure safety and effective grounding. Bonding integrates different metallic systems, allowing them to share the same electrical potential. This is crucial in preventing voltage differences that could lead to dangerous conditions, such as electrical shock or damage to equipment during a lightning strike. By bonding the raceways, any lightning-induced surges can be safely conducted away from the system, reducing the risk of fires or equipment failures.

In addition, proper bonding enhances the overall reliability of the electrical system by minimizing interference and ensuring that all components have a consistent ground reference. This practice is not just a safety measure but also complies with electrical codes to maintain system integrity in the event of a lightning strike.
