Structure Cabling Volume Two Practice Test

NEC stands for National Electrical Code, the standard that governs safe electrical design, installation, and inspection in the United States. It’s published by the National Fire Protection Association as NFPA 70 and covers wiring methods, overcurrent protection, grounding, and electrical equipment to help prevent shocks and fires. Jurisdictions adopt the NEC into local law, and electricians and inspectors rely on it day to day, though the exact requirements can vary by location. The other options don’t fit because they refer to electronics in general, a non-existent or different code, or energy-focused codes rather than the safety rules for electrical systems.
