What readers say
-
This book sets the standard in NEC education. No other textbook takes you through the articles like Michael Hayes' does.

After 14 years as an electrician, I still turn to Michael Hayes' books whenever I need to grasp a Code article quickly and clearly. What truly sets them apart are the Author's Comments. They explain the reasoning behind each requirement, which is essential when real-world situations don't match the exact scenarios in the Code.

I used Michael Hayes' books to pass my master electrician exam on the first try after failing twice with other resources, and the difference was immediate. Most NEC study guides simply summarize the Code. This one actually explains it.

As an electrical inspector, I rely on Michael Hayes' materials both for continuing education and as a day-to-day reference when verifying my interpretation of Code requirements. The Author's Comments clearly explain the intent behind the rules, which is exactly what you need on the job.
