2011 Understanding the National Electrical Code Volume 1 & 2 Combo - SAVINGS!

I have learned quit a bit from the easy format you explain the NEC Code in the Understanding the NEC books. Thank you for providing such a clear and concise material....you provide a great service and value.



I teach electrical safety classes and conduct technical assistance all over the state of Kentucky. I generally place your Understanding the NEC as well as your Bonding and Grounding books on a table along with the regulations at most of my classes. Thanks.

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.

You guys seem to genuinely value my business. I have been a control technician for 24 years and recently was approached by my company to get my journeyman's license. Your Understanding the NEC library looked like the most detailed course out there. You guys are great!

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.
