Power-limited circuits may be wired using which approach?

• A. Chapter 3 wiring methods
• B. Non-power-limited wiring methods
• C. Power-limited wiring methods
• D. Mixed-method installations

Answer: (C)

Power-limited circuits operate with a restricted amount of energy, so the wiring approach must be designated for power-limited use. Using wiring methods that are specifically approved for power-limited circuits ensures the cable construction, insulation, and installation rules match the low-energy nature of these systems. This alignment helps keep overcurrent protection, voltage levels, and separation requirements appropriate for PL circuits, which enhances safety and code compliance. Chapter-wide or non-power-limited methods are not tailored to these low-energy conditions, and mixing methods can complicate compliance and the safeguards built into the installation. So the proper approach is to wire power-limited circuits using power-limited wiring methods.
