The NESC protects the public as well as utility workers, as it is the authoritative code for ensuring the continued practical safeguarding of utility facilities during the installation, operation, and maintenance of electric supply and communication facilities (i.e. power, telephone, cable TV, and railroad signal systems).
It’s the industry consensus standard, produced exclusively by IEEE and approved by the American National Standards Institute (ANSI), revised every five years to address new technologies impacting electrical safety requirements. The latest revision to the NESC came in 2017, and includes some new rules changes and exceptions, while also introducing updated tools to more easily access NESC content. Many of these updates were made in an effort to make the code more logical and useful for current and up-and-coming engineers.
