Illustrated Guide to the NEC represents a dramatic blend of new presentation styles with tried-and-true teaching practices. This text teaches through visualization. Technically accurate, highly detailed illustrations offer insight into Code requirements, and are further enhanced through clearly written, concise blocks of text which can be read very quickly and understood with ease. Information formerly scattered throughout the Code book has been logically gathered and concentrated under the appropriate occupancy: one-family dwellings, multi-family dwellings, illustrated accordingly. After presentation, summaries review the material, while competency tests reinforce what has been learned. Illustrated Guide to the NEC offers a visually pleasing format which stimulates interest and facilitates comprehension, making both teaching and learning easier and more enjoyable.
A delightful read if you're into subjects like these. Certainly better than reading the code itself, although relevant sections are referenced. Just be mindful that this edition refers to the 2014 code ( updated every three years ) and is currently good for states like Pennsylvania but not for Massachusetts which now uses the 2020 Edition of the code. But I suspect for typical residential work, the 2014 Edition is sufficient.
