Hello, My name is Richard.
I am currently working in a FM-200 server room that isn't passing the fan pressurization test. The general contractor is stating that our conduits supplying a 120/208 100amp panel inside the room requires the inside of our conduits to be filled with a sealant. I have had no luck proving this either way with in the NFPA 70.
Can you help locate this with in the NFPA 70??
