it has some nice pictures…but is very basic in code referenced items that I hope most HI’s should know anyway. It is a good learning tool to the newbie.
I will tell you however the DEWALT “Electrical Professional Refererence” is a very nice reference guide for Electrical Inspectors and Engineers. I so far have only found (1) thing incorrect in it and that was VERY minor. The book is small and nice and handy and has MANY references that go way above my head as well…but very nice to have.
