NFPA 70 : National Electrical Code (NEC) Edition 2017
NFPA 70®: National Electrical Code® (NEC®) Softbound, 2017
Many new and revised requirements in the 2017 NEC® impact residential, commercial, and industrial electrical installations.
- including coverage of higher voltage systems that were once only the utilities' domain. The new consumer role is a major factor in energy decentralization, and expanded NEC coverage is vital for designers, engineers, contractors, and AHJs.
- Large-Scale Photovoltaic (PV) Electric Supply Stations (New Article 691) covers systems that produce at least 5 megawatts (MW) of power, or enough to power 800+ U.S. homes. Energy Storage Systems (New Article 706) governs ESS installation, disconnection, shutdown, and safety labeling.
- Stand-Alone Systems (New Article 710) covers power production sources that are not connected to the grid, including PV and wind-powered systems.

What is NFPA 70?
Soon to roll out across the nation, the National Electrical Code (NEC), or NFPA 70, will set the industry standard for safe electrical design, installation, and inspection to protect individuals and property from potential electrical hazards. The NEC has been adopted by region as part of the National Fire Code series which is published by the private electrical trade association known as the National Fire Protection Association (NFPA).
What does NFPA 70 address?
The NEC addresses the correct installation of electrical conductors, equipment, and raceways; signaling and communications conductors, equipment, and raceways; and optical fiber cables and raceways in commercial, residential, and industrial buildings and structures. Adherence to the code will insure inspection compliance and uphold safety standards industry-wide.
Hundreds of updates have been made to this edition including five entirely new articles to assist electricians to contribute to a safe and efficient electrical future.
Major additions reflect the continuing growth in renewable power technology. The newest NEC addresses the advancement of privately owned wind and solar power generation and distribution equipment. These include detailed coverage regarding higher voltage systems that at one time had been exclusively under the utilities’ ageis. The new consumer role is a major factor in energy decentralization, and expanded NEC coverage is vital for designers, engineers, contractors, and AHJs. Here is a quick overview:
- Large-Scale Photovoltaic (PV) Electric Supply Stations (New Article 691) covers systems that produce at least 5 megawatts (MW) of power, or enough to power 800+ U.S. homes.
- Energy Storage Systems (New Article 706) governs ESS installation, disconnection, shutdown, and safety labeling.
- Stand-Alone Systems (New Article 710) covers power production sources that are not connected to the grid, including PV and wind-powered systems.
- Direct Current Microgrids (New Article 712) concerns independent energy distribution networks that allow the utilization of power from dc sources to direct-current loads. Microgrids are on the rise worldwide.
Other NEC revisions protect the public and workers from deadly hazards.
- New labeling, such as detailed arc flash hazard warning on equipment, helps workers and supervisors assess electrical risks.
- New minimum space clearances for equipment installation clarify the safeguards needed to protect installers and maintainers.
- Fixed Resistance and Electrode Industrial Process Heating Equipment (New Article 425) presents needed regulations for industry.
- Revised provisions for AFCI and GFCI protection improve electrical and fire safety in homes.
Be prepared to protect lives and property in the ever-changing electrical landscape. Order the 2017 National Electrical Code.
Work with the latest requirements governing public and private buildings, homes, and structures; outdoor yards and lots; utility equipment; installations that connect to the power grid; and consumer-owned power generation systems and equipment. The 2017 NEC is better aligned with the safe work practices in NFPA 70E®: Standard for Electrical Safety in the Workplace®. (Hardcover, Approx. 1,400 pp., 2017)
