Power-limited wiring requirements are found in Part ? of Article 760.

• A. I
• B. II
• C. III
• D. IV

Answer: (C)

Power-limited wiring requirements are placed in Part III of Article 760 because the NEC groups fire alarm wiring by energy level and assigns the low-energy, power-limited circuits their own set of rules. These circuits are designed to limit energy and fault current, which changes how they must be installed—things like acceptable wiring methods, insulation, enclosure protection, and separation from higher-energy conductors are tailored to reflect their safer, low-energy nature. By consolidating these requirements in Part III, the code provides a clear, dedicated section for designers and installers working with fire alarm systems that use power-limited wiring. The other parts cover more general provisions and non-power-limited wiring, so they don’t contain the specific rules applicable to power-limited circuits.
