Revised every three years, the National Electric Code (NEC) is the most widely used and accepted criteria for all electrical installations. Containing up-to-the-minute facts and safety guidelines electricians need to avoid costly errors, the NEC remains a "must-have" reference for anyone involved in electrical design installation, identification, and/or inspection--it is adopted as law by most states and cities.
