Steel conduit / tubing for low voltage or communications circuits shall terminate in boxes, enclosures, or wireways.
If steel RMC. IMC or EMT raceways are installed for future use, pull wires shall be provided and the raceways shall be plugged.
Stub raceways for communications circuits are permitted in a suspended ceiling space, basement space or similar area, rather than running the raceway unbroken from outlet to outlet. When the stub-in method is used, a connector, bushing, or other fitting shall be installed at the end of the raceway to protect the cable. Pull wires are to be installed in all stub-in raceways, and provisions are to be made to prevent debris from entering the conduit or EMT.
Bends shall be limited to two 90-degree bends. See Section 4.2.1 (c).
