Which code is primarily concerned with electrical installations in buildings?

• A. NEC
• B. NFPA 70E
• C. NESC
• D. IEEE 802.3

Answer: (A)

The main idea is identifying which code governs how electrical systems are installed in buildings. The National Electrical Code is the standard that specifies wiring methods, conductors, overcurrent protection, grounding, enclosures, and installation practices inside structures. It’s the primary code used by electricians and inspectors to ensure safe, code-compliant building wiring and is widely adopted as law or enforceable standard. Other options focus on different areas: NFPA 70E deals with electrical safety in the workplace and safe work practices rather than installation details; the NESC covers the safety and installation of electrical transmission and distribution lines outside of buildings; and IEEE 802.3 is a networking standard for Ethernet, not building electrical installations.
