Understanding the National Electrical Code, Vol. 1 (textbook), 2017 NEC

I studied Mike Holt back in 1990 to pass my Dade County master exam. What a dishonor I've done to my self by not continuing to learn. This Understanding The National Electrical Code Volume 1,2 is the most incredible Code learning system ever written Thank you ,Gracie for advising me to purchase this. And tell Mike that he has used God's gift perfectly. Thank you.

I have been teaching code classes at our community college (Cuesta) for the past several years. This year I decided to use some of your books as a teaching aid for my NEC class. What a pleasant surprise - Understanding the NEC is the greatest. The illustrations are clear and easy to understand. I am finding when a student is having trouble grasping a concept, I can simply hand them the book, and it becomes clear to them what I am trying to convey. It’s like having a code specialist with me in the classroom.

Continue to write comments next to the graphics. I have been using your training material for the last 12 years not only to understand the Code but to clearly discuss projects.Keep up the good work.

I find that all Mike Holt products and articles are the most professionally and clearly presented of anything on the market. I particularly like the distinctive styles of the illustrations in Understanding the NEC.
