National Electrical Code 1999

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