We use a 25 pair as a trunk line that runs through the purlin of the building the whole length. The door sensors screw onto the rail of each of the roll-up unit doors,(4' from floor) the switch has a 22/2 lead that extends up to the 25 pair in the purlin and connects.
We secure the 22/2 lead with holy ties all the way up and make sure it is routed in a way that protects it from physical damage.
I've recently been told that any wire below 8' needs to be in conduit, but I have yet to find any code (art. 800) that states this.
I assume the code is for any voltage carrying wire and not for a simple dry contact wire.
Any input is appreciated so I can prove my boss wrong!!:lol:
