2008 National Electrical Code Looseleaf

Industry-driven changes in the 2008 NEC® redefine electrical safety! Your new 2008 National Electrical Code Looseleaf Edition from Construction Book Express is now available!

Be prepared to comply in the new era for electrical safety. The NEC protects the public by establishing requirements for electrical wiring and equipment in virtually all buildings. As the field's most important document is revised based on industry needs, reserve your 2008 NEC Looseleaf to stay competitive and up-to-code!

Revisions in the 2008 National Electrical Code boost public safety, emergency preparedness, Code usability, and worker protection. Only the 2008 NEC includes the latest rules for electrical installation in residential, commercial, and industrial occupancies. It also introduces:

• New article on Critical Operations Power Systems with provisions for electrical security in public and private facilities that must stay online during a crisis, such as public safety dispatch centers and hospital ICUs.
• New article on Electrified Truck Parking Spaces with NEC rules for outlets to run on-board electrical systems, reducing truck emissions and fuel consumption caused by idling during driver rest times.
• New provisions in Article 210, Article 410, and elsewhere in the Code reduce worker hazards and correlate with NFPA 70E ® worker safety rules.
• Plus hundreds of other revisions

Usability changes facilitate your work! You'll find greater consistency in grounding and bonding terminology…new shading behind revised text that lets you see what's new at a glance…and new identifiers at the top of each page in the NEC index for speedier referencing.

The NEC Looseleaf is a must for electrical contractors, engineers, electricians, fire service professionals, safety officials, inspectors, and architects. (Looseleaf, Approx 864 pp., 2008)
