Query: Not a handbook

I would NOT recommend this book to any electrician, engineer, or architect. It is extremely difficult to comprehend. Gaining any practical information from this book is futile. I have had the twelfth edition over ten years. I used it to study for the electricians exam. I hated it then. Since that time, I have found it to be a very poor reference book. The thirteenth edition is no better. I understand why some electrician training schools might use this book - it is very comprehensive. It would make a good reference for a classroom lesson plan, but not a direct teaching tool. If you want to learn the material in this book, get the National Electric Code Handbook (and related materials published by the NFPA) and appropriate textbooks. FYI - I am a licensed electrician and a registered professional engineer.
