The NEC states that a non-metallic sheathed cable be secured by staples or straps within _________ from every cabinet, box, or fitting?

• A. 12 inches
• B. 6 inches
• C. 18 inches
• D. 24 inches

Answer: (A)

Non-metallic sheathed cable must be secured close to where it enters cabinets, boxes, or fittings to prevent movement that could loosen terminations or damage insulation. The NEC requires staples, straps, or similar fittings to secure NM cable within a short distance from every cabinet, box, or fitting, and then at regular intervals along the run. The standard distance is eight inches from the box, cabinet, or fitting, with additional supports at intervals not exceeding about four and a half feet. So the first securing should occur within eight inches, not twelve. If the option shows twelve inches, it does not meet the NEC requirement, even though the idea is to keep the cable secured near the enclosure.
