Hi forum Members,
While conducting a fire alarm inspection, I notice pull stations in a warehouse with FPL (Red wire) running from the overhead (15 ft) down the support beam to a pull station. The wire was completely exposed. The pull Station is mounted 42 inches above the floor.
My concern is; Should the wire running down the beam be protected, Ran in conduit?
I found some training material stating it should be protected to 7 feet above the floor, but the NEC 760 is not specifically (alluding too) stating this requirement that I can comprehend. Can someone please clear this up for me?
