What is the purpose of the NEC (National Electrical Code)?

The primary purpose of the NEC, or National Electrical Code, is to establish guidelines and requirements that ensure the safe installation and operation of electrical systems. This is primarily focused on the practical safeguarding of persons and property from electrical hazards such as shock, fire, and other dangers associated with electrical installations. By adhering to the NEC, electricians and builders can minimize risks and enhance safety in the environments where electrical systems are utilized.

While the code may reference best practices that can aid in design and installation, its core intention is not to serve as a design manual or instruction guide. Rather, it provides enforceable standards intended to protect public safety. By following the guidelines set out in the NEC, practitioners of the trade can ensure compliance with legal requirements while promoting safety in electrical work.
