NEC® Article ___ covers cables for power-limited circuits and fault-managed power circuits.

• A. 725
• B. 750
• C. 770
• D. 722

Answer: (D)

Cables used with power-limited circuits and fault-managed power circuits are addressed by a NEC article that specifically governs how those cables must be constructed, rated, and installed to keep the system within its limited power and protective requirements. This article defines what counts as a power-limited circuit, and it lays out which cable types, insulation, and voltage ratings are permitted, along with any listing and marking requirements. It also covers installation rules to prevent these limited-power conductors from being treated like higher-power circuits, ensuring that the fault-management features remain effective. In practice, when you’re selecting cables for Class 2/Class 3 or other power-limited arrangements, this article is the reference that ensures compatibility and safety for those circuits.
