Over the years, the National Electrical Code® has grown in volume and complexity. This updated edition utilizes visualization to present a complete, concise, and easy-to-understand exploration of the 2005 Edition of the NEC®. Each highly-detailed illustration offers insight into Code requirements and is enhanced by clearly written text blocks that read quickly and with little effort. Includes coverage of fundamental provisions, followed by Code requirements relevant to specific types of occupancies. Intended as an indispensable supplement to the NEC®, this book translates the sometimes vague and complex language of the Code into clearer, cleaner, and simpler terms.
