I recommend this book to fellow students anywhere. I am a first year electrical student at Metro Community College's South Omaha campus in Omaha, NE. Electrical grounding is one of the most important areas to educate yourself if you are going into the field or if you are a seasoned professional. Loss of life, property damage and potential lawsuits are what await those who do not educate themselves. Fortunately, this book is very easy to read.

As a journeyman electrician studying for my supervisors card, I can tell you that nobody clarifies electrical grounding requirments like O'Riley. I used his text books when I was an apprentice eons ago. Electrical grounding is not hard to understand if you read and study this book.

It's hard to take this book seriously when it states (p. 8) "The term neutral is not defined in Article 100 of the Code. The term is used very sparingly in the Code. Theoretically, there should be no potential difference between the neutral conductor and ground." In fact, in the 2005 NEC Handbook, it is used twice in Article 100, and 644 times overall. (It appears 315 times in the NEC itself.) Further, the neutral is not always grounded. In a large sidebar in Article 200 of the Handbook, it states "The grounded conductor is often, but not always, the neutral conductor. For example, in a single-phase 2-wire or in a 3-phase corner-grounded delta system, the intentionally grounded conductor is not a neutral conductor." The author seems to have an inadequate grasp of his topic, both conceptually and factually. The NEC Handbook is a far better use of readers' time and money.
