About the nesc
Published exclusively by IEEE, the National Electrical Safety Code (NESC) sets the ground rules for practical safeguarding of persons during the installation, operation, or maintenance of electric supply and communication lines and associated equipment. The NESC contains the basic provisions that are considered necessary for the safety of employees and the public under the specified conditions.
In 1972, IEEE was designated as the secretariat for the NESC. The NESC continues to be a stronghold in the U.S. electrical industry and communications utility field, and serves as the authority on safety requirements for power, telephone, cable TV, and railroad signal systems.
NOTE: NESC rules do not cover installations in mines, ships, railway rolling equipment, aircraft, automotive equipment, or utilization wiring (with some exceptions).
