The distance between a cable tray and the raceway(s) or equipment shall not exceed how many feet?

• A. 3 ft
• B. 9 ft
• C. 12 ft
• D. 6 ft

Answer: (D)

The idea here is to keep cable routing close enough that terminations, splices, and connections remain reachable and protected. The rule sets a maximum of six feet between a cable tray and the raceways or equipment it serves, so you shouldn’t have a tray segment more than six feet away from the nearest raceway or device. This ensures the wiring path stays orderly, reduces the risk of damage from movement or over-extension, and makes servicing easier. Shorter distances would still meet the rule, while distances longer than six feet would not.
