National Electrical Code lays the foundation for electrical safety in residential, commercial, and industrial occupancies throughout the world. It is constantly reviewed and updated, with input from professionals active in the field, to stay ahead of the constant changes in technology and security that affect your work every day. This is reflected in the new 2020 edition of this trusted code, which includes the latest requirements for electrical wiring, overcurrent protection, grounding, and equipment installation. This commitment to up-to-date knowledge keeps you and your colleagues well-prepared for professional challenges and exciting opportunities.
The NEC tries to guarantee electrical safety in all installations regardless of the legality of the activities conceived in them. For example, in 2023, the new NEC Section 512 will regulate marijuana butane honey operations, which are a felony to operate under US federal law.
The “competent authority” inspects compliance with these standards.
