Summary

The second edition of Illustrated Guide to the National Electrical Code® leads professional electricians, electrical inspectors, and readers on a visual tour through the entire 2002 NEC®, conveniently grouping Code requirements according to type of occupancy, including: one-family dwellings, multi-family dwellings, commercial locations, and special occupancies and equipment. Central to the book are more than 600 technically precise, highly detailed illustrations that convey insights into NEC® requirements and reduce the potential for misinterpretation of the sometimes vague and often complex language of the Code. Concise phrases and short blocks of text that can be read quickly and understood easily further enable the reader to understand what is depicted in each graphic. Now thoroughly updated based on the 2002 NEC®, this indispensable explanation of the Code also features a section on fundamentals making it equally well suited for use by the novice and master electrician alike.
