Preface: I'd like to avoid the question of whether one should run data and power together; my question is focused on Code compliance.
I'm trying to ensure I interpret Code correctly when running Cat 5/6 cabling and power together in the same conduit. For starters, I understand that nothing in Code prohibits one from doing this; I'm trying to ensure I understand how to do it properly.
I'm wiring a basement office for power and data, and I'll be running the electrical in EMT. My plan was to pull THHN for the power rather than pull NM-B, but then 800.133(2) Exception 1 made me scratch my head. Is my understanding of the Article that if I want to run both data (Cat6) and power in the same conduit, that the power needs to be sheathed (i.e. NM-B). Is it unacceptable to pull individual THHN conductors and the Cat6 together in the same conduit?
800.133 2) Other Applications. Communications wires and cables shall be separated at least 50 mm (2 in.) from conductors of any electric light, power, Class 1, non–power-limited fire alarm, or medium-power network-powered broadband communications circuits.
Exception No. 1: Where either (1) all of the conductors of the electric light, power, Class 1, non–power-limited fire alarm, and medium-power network-powered broadband communications circuits are in a raceway or in metal-sheathed, metal-clad, nonmetallic-sheathed, Type AC, or Type UF cables, or (2) all of the conductors of communications circuits are encased in raceway.
