    Follow the latest safety requirements for power, telecommunications, cable TV, and railroad signal systems in the 2017 edition of the National Electrical Safety Code®.

    Work with the authoritative source for electrical engineering safety practices -- now it its 100th anniversary edition. The 2017 edition of the National Electrical Safety Code (NESC) provides practical guidance to help safeguard employees and the public from hazards during the installation, operation, and maintenance of electric supply and communication lines and associated equipment.

    The Code covers a broad range of areas including storage batteries, transformers and conductors to switchgear, circuit breakers, physical clearances, cable terminations, safety warning signs, and protective clothing for workers installing electrical equipment.

    Changes in the 2017 NESC reflect new technologies and provide solutions to new challenges in today's field. Major revisions include:

    • Revised purpose rule to include only the safeguarding of persons and utility facilities, along with clarified rules for application
    • Deleted unused definitions and adding definitions for communication and supply space
    • Revised requirements for substation impenetrable fence
    • An added exception to exempt underground cable grounding requirements from the 4 grounds in each mile rule under certain conditions
    • Revised and reorganized rules for guy insulator placement, along with eliminating the voltage transfer requirements associated with them
    • Requirement for a 40-inch vertical clearance from communication cables in the communication space if a luminaire is not effectively grounded
    • Deleted the conductance requirement for underground insulating jacketed grounded neutral supply cables and revised rules for grounding and bonding for supply and communication cables in random separation installations
    • Revised and reorganized Grades of Construction Table 242-1 that includes service drops
    • Revised strength rules to require that all conductors be considered for damage due to Aeolian vibration
    • Revised rules in Part 4 to align with changes made to 29 CFR by the Occupational Safety and Health Administration (OSHA) 

    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).
