What type of cable is used for branch circuits according to NEC?

• A. Flexible cords only
• B. Only low-voltage cable
• C. Conductors rated for the specific application
• D. Unshielded cables

Answer: (C)

The correct choice highlights the importance of using conductors that are specifically rated for the application at hand when it comes to branch circuits, in accordance with the National Electrical Code (NEC). This ensures safety, reliability, and compliance with established electrical standards. Conductors used in branch circuits must be suitable for their intended use, encompassing factors such as voltage ratings, insulation types, and environmental conditions. The NEC outlines specific standards for different types of conductors to ensure they can handle the electrical loads and conditions they will encounter. Using conductors rated for the specific application guarantees that they can handle the current without overheating or causing any potential hazards, which is a primary concern in electrical design and installation. This approach minimizes risks such as electrical fires, equipment damage, and system failures. In contrast, the other options do not adequately meet the regulatory requirements or practical needs related to branch circuit installations. Limiting use to flexible cords only or to low-voltage cable does not provide the broad applicability needed for various circuits. Unshielded cables may not provide adequate protection in some situations, especially where interference or physical protection is a concern.
