National Electrical Code (NEC)
Also Known As:
The National Electrical Code (NEC) is a standard published by the NFPA (National Fire Protection Association) that sets the requirements for safe electrical design, installation, and inspection in residential, commercial, and industrial settings. The 2020 edition of the NEC incorporates the latest practices, trends, and technologies in the electrical industry to ensure safer and more effective electrical work.
The looseleaf edition of the 2020 NEC offers a customizable format with a durable five-ring binder. Users can insert and organize specific technical information, tables, and other content relevant to their projects within the relevant sections of the code. This allows for easy access and navigation of the code based on individual needs and requirements.
The 2020 edition introduces significant changes and updates, including new requirements for exterior emergency disconnects in one- and two-family dwellings, revised rules for service disconnects to protect electrical workers from arc flash hazards, and adaptations to installation practices for power over Ethernet. Other notable changes include updates to calculations tables for improved energy efficiency, revised ground-fault protection requirements for marinas and boatyards, and the introduction of requirements for safe use of electric vehicles as backup power sources.
