3 new requirements in 2014 National Electrical Code
The National Electrical Code (NEC), or NFPA 70, is a U.S. standard for the safe installation of electrical wiring and equipment. While the NEC is not itself a U.S. law, its use is commonly mandated by federal, state or local law. First published in 1897, the NEC is updated and published every three years. The “authority having jurisdiction” inspects for compliance with these minimum standards, although some jurisdictions do not immediately adopt new editions. OSHA 29 CFR 1910.302-.308 and .399 mandates compliance with portions of the NEC. A thorough understanding of this standard is the foundation for safe and compliant construction of electrical systems.
With the steady introduction of new technologies into the marketplace and the release of new research results by various public and private groups, the National Electrical Code is perpetually changing. Understanding the reason for these changes enables electricians to more easily absorb and implement new rulings.
