Class 2 and 3 circuit conductors or cables shall not be strapped, taped, or attached by any means to ________________________________

Class 2 and 3 circuit conductors or cables shall not be strapped, taped, or attached by any means to ________________________________

• A. the interior of any conduit or other raceway
• B. the exterior surface of any cabinet or box
• C. the exterior of any conduit or other raceway
• D. the outside of any junction box cover

Answer: (C)

Class 2 and Class 3 circuits are low-energy paths that must be kept in protected, dedicated supports to prevent mechanical damage and interference with adjacent systems. The rule specifically prohibits strapping, taping, or attaching these conductors to the exterior surface of any conduit or other raceway because that surface isn’t a listed or secure mounting point for securing low‑voltage cables. Attaching to the outside of a raceway can subject the conductors to abrasion, strain at the strap, vibration, or exposure to moisture and contaminants that the raceway is meant to shield them from. The safe, correct approach is to secure these conductors to appropriate listed supports or within their own raceways, not to the exterior of a conduit or raceway.
