The National Electrical Safety Code® (NESC®) was introduced in 1914 — the product of a congressional mandate for the National Bureau of Standards (NBS) to investigate the hazards of electrical work, contemporary engineering theory and generally accepted good industry practice. Over decades, the Code has emerged as a foundational element in the culture of safety that has grown up around the business of installing, operating and maintaining both underground and overhead electric supply and communication lines, as well as conductors and equipment in electric supply stations. Utilities, their employees, contractors and manufacturers — as well as telephone companies, cable TV providers, railways and other organizations in the exercise of functioning as a utility — look to the NESC for practical safeguarding guidelines. IEEE’s National Electrical Safety Code (NESC) is also known as American National Standard C2. It is a consensus standard that has been prepared by the National Electrical Safety Code Committee under procedures approved by the American National Standards Institute (ANSI). The membership of the NESC Committee is composed of national organizations and is certified by ANSI as having an appropriate balance of the interests of members of the public, utility workers, regulatory agencies, and the various types of private and public utilities. Utility regulators in the US and more than 100 nations use the Code at least in part. Published exclusively by IEEE, the NESC is revised every 5 years to keep the Code up to date and viable.
