Raised Floor Conductor Securing when placed directly on sub floor must be at intervals no greater than?

• A. 8 ft
• B. 10 ft
• C. 12 ft
• D. 14 ft

Answer: (C)

Regular securing of a raised floor conductor that sits directly on the subfloor is needed to prevent movement from foot traffic, equipment shifts, and thermal cycling. This keeps the cable aligned, protects terminations from stress, and maintains the integrity of the installation along its whole length. The standard practice is to secure at a fixed interval of twelve feet, which provides consistent support without adding excessive fastening work. Shorter intervals would be unnecessarily labor-intensive, while longer ones could allow sag or movement that risks damage.
