by Mike Holt

Mike Holtís Illustrated Guide to Understanding the National Electrical Code, Volume 1 has proven itself in the field and in the exam room.

Compliance with the National Electrical Code is a major concern for todayís engineers, designers and electricians.

On the one hand, you need to keep job costs down. On the other hand, your electrical projects must meet Code. And if you are an electrical inspector, youíve got to ensure compliance with the Code in a way that is fair, accurate, equitable, and consistent.

The need to understand and accurately apply the NEC is great. How can you make sure you get this right? The answer is Mike Holtís Illustrated Guide to Understanding the National Electrical Code.

No other textbook takes you step-by-step through NEC articles like Mikeís authoritative Understanding the National Electrical Code textbooks. What makes this book so effective is the clear writing style, the Authorís Comments, and the amazing detailed full-color illustrations that help you visualize the concepts being discussed.

The chapter questions help you test your knowledge as you go. This book sets the standard in NEC education, and is used extensively throughout the country.
