The recent NEC changes are significant and widespread. Many revised and all-new requirements in this edition will have an impact on electrical work industrywide.

  • Expanded AFCI and GFCI protection in homes 
  • Continued emphasis on making installations safe for electrical workers
  • New Code coverage of new methods to distribute low voltage power
  • New approaches toward ensuring the safety of photovoltaic (PV) electric systems
  • Plus hundreds of other revisions that allow for the safe implementation of the latest in electrical system and equipment technology

Four all-new articles expand NEC coverage.

You’ll work with added coverage for growth industries and other important areas:

  • Low Voltage Direct Current Distribution Systems (Article 393)
  • Modular Data Centers (Article 646)
  • Fire Resistive Cable Systems (Article 728)
  • Energy Management Systems (Article 750)

Major changes in the new Code also respond to electrical safety concerns:

  • New centralized locking requirements in revised section 110.25
  • Revisions in section 110.21(B) dealing with field marking of equipment

The 2014 NEC improves the safety and efficiency of green energy systems.

  • New direct current (DC) provisions are designed to save energy lost in conversion from AC.
  • Voltage thresholds are increased from 600 to 1,000 volts to be consistent with alternate energy technologies. 

You can identify Code changes fast with shading for revised Code text and vertical rules indicating new articles, tables, and figures
