At what interval must the AWG size be marked on nonmetallic sheathed cable, according to regulations?

• A. 12 ft.
• B. 18 ft.
• C. 24 ft.
• D. 30 ft.

Answer: (C)

The requirement for marking the AWG (American Wire Gauge) size on nonmetallic sheathed cable is important for ensuring safety and compliance with electrical codes. The regulations stipulate that the wire size must be marked at intervals not exceeding 24 feet. This is to provide easy identification of the conductor size throughout its length, which is critical during installation and future inspections. Proper marking helps in determining the current-carrying capacity and ensuring that the wiring meets the necessary specifications for the project. Hence, indicating the AWG size at this specific interval aids in promoting safety and electrical code compliance.
