NEC Article 722 addresses which category of circuits?

• A. cables for power-limited circuits and fault-managed power circuits
• B. communications circuits
• C. audio signal processing equipment
• D. general lighting circuits

Answer: (A)

Power-limited circuits are designed to carry limited energy to keep shock and fire hazards low. NEC Article 722 governs these circuits and the cables and equipment used for them, including fault-managed power circuits. This makes it the category that to articles specifically addresses. Communications circuits are covered under Article 800, general lighting circuits fall under other sections focused on lighting and power distribution, and audio signal processing equipment isn’t a distinct NEC circuit category. So the scope of Article 722 is about cables and components for power-limited, and fault-managed, power circuits.
