Which NEC Article covers cables for power-limited circuits and fault-managed power circuits?

• A. Article 210
• B. Article 410
• C. Article 726
• D. Article 722

Answer: (D)

Cables for power-limited and fault-managed circuits are governed by a NEC section that specifically defines these types of circuits and lays out the rules for the cables used with them. This article sets the scope and requirements for the conductors, insulation, and installation methods appropriate for low-energy, controlled circuits, including any labeling or protection needs. Because it directly addresses the kinds of cables used in power-limited and fault-managed configurations, it’s the best reference for this question. Other articles cover different areas (ordinary branch circuits, lighting equipment, or other low-voltage systems) and do not provide these specific cabling rules.
