NFPA 70 (National Electrical Code)

NFPA 70, commonly known as the National Electrical Code (NEC), is a set of safety standards for electrical installations in the United States. Developed by the National Fire Protection Association, it aims to protect people and property from electrical hazards, such as fires and shock. The Code covers guidelines for wiring, equipment, and systems in homes, businesses, and public spaces, ensuring that they are safe and reliable. Compliance with the NEC is required for new electrical work and renovation, and it is updated every three years to incorporate new safety practices and technologies.
