From an inspector/instructor point of view your product is very user friendly. The book on Grounding versus Bonding makes it so easy to explain to others and the illustration are great. If all your books on the NEC are as good as this one I plan to get most of them! Thanks Tommy Hall -------- You do a GREAT job. The material is easy to understand. Gail Beery I purchased the Grounding vs. Bonding book to help me prepare for a presentation. The information in the book was very well explained and the illustrations were extremely helpful. Thanks for all of your hard work in preparing this book. Rick Meadows
