Name two major U.S. electrical safety codes and their primary focus.

• A. NEC focuses on wiring and electrical installations; NFPA 70E focuses on electrical safety in the workplace
• B. NEC focuses on building codes; NFPA 70E focuses on HVAC safety
• C. NEC focuses on consumer electronics; NFPA 70E focuses on fire safety in homes
• D. NEC focuses on weather safety; NFPA 70E focuses on water safety

Answer: (A)

The main idea here is that two widely used U.S. electrical safety standards cover different parts of the electrical system. The NEC, or National Electrical Code, is the primary rulebook for how electrical systems should be designed, wired, installed, and protected in buildings and other structures. It sets the technical requirements for conductor sizing, overcurrent protection, grounding, wiring methods, raceways, boxes, and electrical equipment installations to prevent hazards from the source up through the distribution. NFPA 70E, on the other hand, concentrates on electrical safety in the workplace. It deals with how workers should interact with electrical equipment—training, procedures, hazard analysis, lockout/tagout, and the use of personal protective equipment—to minimize shocks, electrocution, and arc-flash injuries. It’s about safe work practices and protecting people who maintain or operate electrical systems. So, the NEC governs safe design and installation of electrical systems, while NFPA 70E governs safe work practices and worker protection around those systems. They complement each other, ensuring both that electrical installations are done correctly and that people who work on them are protected.
