reference

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.

Another motley McGraw-Hill product. First copyrighted in 1913. The author appears to have died prior to 1976, and the book has been maintained by hired help. Don't try to use this as a textbook; treat it as a reference only. You never really know whether some item is up to date or 50 or 80 years old. Examples: There is a lot of treatment of two-phase (yup, 90 degrees) power, including at 25 hertz, and of multi-kilovolt series incandescent streetlighting, plus knob and tube wiring. Also, it is stated that the highest radio frequency in use is 30 megahertz, whereas in reality we're up to 1,000 or 2,000 times that just now. This book is a curiousity; charming if you have the cash, but if you don't, maybe you should be getting something more coherent.

W A R N I N G: This book is not for the weekend repairman!!!

This is a very intense book for the professionals or for someone who would like to further their knowledge. This truely might be the last book an electrican will ever buy. A must for your library!
