About the NEC®
NFPA 70®, National Electrical Code® (NEC®), sets the foundation for electrical safety in residential, commercial, and industrial occupancies around the world. It is consistently reviewed and updated with input from active professionals in the field to help you stay ahead of the curve and, more importantly, safer on the job.
The 2023 edition features significant alterations to modernize the code to present-day standards, including updated requirements for all electrical systems—both residential and commercial—and new articles for never-before covered systems and equipment, including Class 4 fault-managed circuits.
