The year 2020 provided me with the unique opportunity and the time to produce a series of videos on topics that you told me were of interest to you. I recorded them from my house, and livestreamed them over the course of several months. There were a lot of you that might not have been able to tune in, and others who did, but would enjoy the chance to see them again. We'll be sending them out monthly in a newsletter series. Enjoy and feel free to share!
 Lightning is the discharge of electrostatic charges within clouds, other clouds, the Earth, and sometimes space [Sprites]. An NFPA 780 compliant lightning protection system can be installed to protect a building or structure from damage. Still, it must be bonded to the building grounding electrode system in accordance with the NEC [250.106] to limit voltage differences between it and the electrical system wiring.
One thing often misunderstood is that the lightning protection electrode isn't permitted to be used for the grounding electrode system required for service equipment [250.24(A)(1)], separately derived systems [250.30], or remote building feeder disconnecting means [250.32(A)].
Join Mike as he discusses what lightning is and how the NEC requires a lightning protection system to connect to the electrical system..
