The National Electrical Code (NEC) is a set of guidelines and standards for electrical installation and safety in the United States. It is published by the National Fire Protection Association (NFPA) and is updated every three years. The NEC is also known as NFPA 70 and provides minimum requirements for safe electrical installation practices and is adopted by many states, cities, and municipalities as law.
The NEC covers a wide range of topics related to electrical safety, including wiring methods, grounding and bonding, electrical equipment installation, overcurrent protection, and much more. The code aims to prevent electrical hazards, such as electrical fires, electrocution, and other dangerous electrical events.
The NEC is widely used in the United States by electricians, engineers, building inspectors, and other professionals involved in the design, installation, and maintenance of electrical systems. It is an important resource for ensuring electrical safety and minimizing the risks associated with electricity.
