Where must communication circuit conductors or cables be attached?

• A. to the interior of any conduit or raceway
• B. to the exterior of any conduit or raceway
• C. around the insulation of the conductor
• D. suspended from any support without attachment

Answer: (B)

In low‑voltage cabling, the proper way to secure communication cables is to attach them to the exterior of the conduit or raceway. This keeps the interior clear for the protective path of the raceway and prevents the cable from being damaged by internal clamps or fittings. Attaching on the outside allows you to use standard supports, straps, or clamps to secure the run at appropriate intervals, while the cable inside the conduit can pass freely and be protected by the conduit itself. Attaching to the interior would risk damaging insulation, complicate the conduit fill, or interfere with the pull, and attaching around insulation or suspending without attachment wouldn’t provide the necessary secure support.
