Closing Paragraph

The 2020 edition of NFPA 70, National Electrical Code, provides a critical set of regulations for ensuring electrical safety across diverse applications. By adhering to the NEC's requirements, professionals can design, install, and inspect electrical systems that minimize the risk of fires, shocks, and other electrical hazards.

Note: The NEC is a code, not a book in the traditional sense. It doesn't have chapters with narratives but uses a structured system of Parts and Articles containing specific regulations.
