• C. Article 300
• D. Article 250

Answer: (C)

General wiring methods and installation requirements are defined in Article 300. This section lays out the permitted wiring methods, conductors, raceways, and cables, along with the rules for how they must be installed, protected, supported, and routed inside and outside of structures. It covers the specifics of securing and spacing, enclosure types, and the conditions under which different methods are allowed, ensuring installations remain safe and compliant. The other articles address different areas: one introduces the code and how it’s used, another provides definitions used throughout the NEC, and another covers grounding and bonding requirements.
