Q. Please explain how I'm supposed to ground a service on a building that has a ground ring used for the lightning protection system grounding electrode?
A. If a lightning protection system is installed on a building/structure, it must be bonded to the building/structure grounding electrode system as per 250.106. The grounding electrode for a lightning protection system must not be used as the required grounding electrode system for the buildings or structures [250.60].
