| | I have 900 pair copper running in multiple conduits underneath a building exiting into a dropped ceiling space, never leaving the building. What are the general guidelines that I need to follow regarding Lightning Protection? |

| If you never leave the building you fall under the cone of protection. I would make sure any metallic raceways are grounded properly.

| | Mr. Hobbs is absolutely correct. If you need backup you can reference the NEC Article 800.90. Informational note 2 section 2 is the area to find the legal speak for the "cone of protection" he is mentioning. |
