What does NFPA 70 cover in relation to electrical installations?

NFPA 70, also known as the National Electrical Code (NEC), specifically provides guidelines and regulations for safe electrical installations to protect people and property from electrical hazards. It is a comprehensive standard that addresses various aspects of electrical work, including wiring methods, grounding, Overcurrent protection, and the installation of appliances and equipment. The NEC sets forth the minimum requirements for safe electrical design, installation, and inspection, ensuring that electrical systems are installed correctly and operate safely.

While commercial regulations and residential safety standards may intersect with the NEC, they do not encompass the full breadth of electrical safety and installation methods that NFPA 70 covers. Fire alarm codes, on the other hand, though they may be influenced by NEC principles, are primarily concerned with fire alarm systems and are governed by different standards specific to fire safety. Thus, referring to NFPA 70 explicitly as the National Electrical Code precisely describes its primary function in relation to electrical installations.
