2011 Grounding Vs. Bonding, Article 250, DVD
Excellent product and advice. The DVDs are proving themselves invaluable for the electricians within our agency. They are saving our instructors countless hours of course preparation and providing excellent training at the same time resulting in meeting agency training goals and saving taxpayer money.

Thank you and keep up the good work you're doing.

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
