National Electrical Safety Code® (NESC®)


Published exclusively by IEEE, the NESC sets the ground rules for practical safeguarding of persons during the installation, operation, or maintenance of electric supply & communication lines & associated equipment. It contains the basic provisions that are considered necessary for the safety of employees & the public under the specified conditions.

In 1972, IEEE was designated as its secretariat. The NESC continues to be a stronghold in the U.S. electrical industry & communications utility field, & serves as the authority on safety requirements for power, telephone, cable TV, & railroad signal systems.
