We at Mike Holt Enterprises try to provide as much as we can to the industry at no charge. For this reason we’ve created a free “Top 101 NEC Rules” textbook. The material in this textbook was extracted from Mike's Understanding the 2005 NEC textbook.

It’s a quick reference and guide to make sure you’re up to speed on these very important rules.

Because of the size of the textbook we’ve decided to make it available in four parts. Last month we made Part 2 available, in May we sent Part 1 and now you can download Part 3:
