The National Electrical Code (NEC) includes specific requirements intended to ensure safety and protection in habitable spaces. The NEC is widely recognized as the standard for safe electrical installation practices in the United States. It stipulates guidelines related to electrical wiring, grounding, and other vital safety measures that help prevent electrical hazards in areas where people live and work.

Using the NEC helps to establish a baseline for acceptable safety practices, including provisions for the protection of circuits and equipment, as well as requirements for the adequate installation of electrical systems. This ensures that occupants of these spaces are adequately protected from potential electrical hazards, such as shock or fire.

Other organizations, while important in their respective areas, do not directly compile a code that includes safety requirements specifically for habitable spaces. For example, the Institute of Electrical and Electronics Engineers (IEEE) provides standards more focused on electrical engineering practices and technology rather than residential electrical safety. The National Electrical Manufacturers Association (NEMA) primarily develops standards related to electrical products and equipment, rather than installation practices. Underwriters Laboratories (UL) focuses on product safety testing and certification but does not provide a comprehensive code covering installation practices like the NEC does.
