The NESC and changes in the 2023 Edition


12.0 Professional Development Hours (PDH)

The 2023 Edition of the NESC® (ANSI C2-2023) was published on August 1, 2022. It will go into effect in most jurisdictions on February 1, 2023. The NESC is the national standard for safety in the design, construction, operation, and maintenance of electric utility supply and communication systems. 

Even where compliance with the NESC is not legally enforced, employees of utilities and their contractors have a moral responsibility to design, construct, operate and maintain electric supply and communication systems in a safe manner. When incidents involving utility systems cause death, injury, and property damage, litigation is often based on claims of non-compliance with the NESC.

Course Overview:

During four half-days of intensive, interactive presentation and learning exercises, you will explore the Code’s origin and purpose as well as significant rules and changes for electric supply stations, overhead line clearances, conductor and structure mechanical loading, underground lines, and grounding

Who Should Attend:

  • Anyone responsible for the design, construction, operation, maintenance, or safety of electrical or communications supply systems 
  • Electrical Engineers 
  • Technicians
  • Line workers
  • Electricians

Additional Information:

This course requires the latest NESC 2023 codebook released in August 2022. It can be purchased in print or PDF format at :
