National Electrical Code, 2020

Throughout the United States and around the world, NFPA 70®, National Electrical Code® (NEC) sets the foundation for electrical safety in residential, commercial, and industrial occupancies. The 2017 edition of this trusted Code presents the latest comprehensive regulations for electrical wiring, overcurrent protection, grounding, and installation of equipment.

NFPA 70, NEC has been published since 1897, and a rigorous process of review keeps it up-to-date with new technologies.

Proposed Updates for the 2020 edition:

  • Horticultural Lighting: Increasing safety at indoor facilities that demand intense electrical loads.
  • Conducting Load Calculations: Modernizing the tables currently in use for calculations to reflect improvements in energy efficiency.
  • Power Over Ethernet: Reducing the risk posed by delivering power with communications cables in “smart” buildings.
  • Marina and Boatyards: Updating ground-fault protection and leakage-current measurement device requirements.
