I spent quite a bit of time researching to find a good book on residential wiring for a rewire project I was looking to tackle in my early 1900 house. In the end, I purchased three books:
1. Electrical Wiring Residential - by Mullin
2. Wiring a House (for Pros by Pros) - by Cauldwell
3. Complete Guide to Home Wiring (Black and Decker)
Unfortunately I have to say that I found this (Mullin's book) to not be user friendly. While I think there is a wealth of information within the book, it is not organized in a very logical manner and tends to be filled with pages of details that aren't that meaningful for most readers.
For example, Chapter two spends quite a bit of time discussing electrical symbols commonly found on an electrical plan [how many people really need to know this?]. Then, intermixed in Chapter two is information of the number of wires in a box, selecting the right size box, etc. [important info for most people doing a wiring job]. Further, the specific NEC code is typically co-mingled with other [often not important] information throughout chapters, making it very hard to easily find code requirements on a specific topic. Point being, the book isn't logically organized, basically to the point of being distracting.
My recommendation to the author would be to have chapters laid out in a more logic manner (i.e. a chapter on a specific topic, e.g. a chapter on wire, a chapter on boxes, a chapter on lighting, a chapter on recetacles, etc.) and to have a consistent approach to where the code requirements would be found in each chapter (e.g. at the end of the chapter), so it is is always easy for the reader to find.
As side note, this book does not have any information on old wire and minimal information on doing a rewire project. Further, it does little to provide meaningful and helpful/practical hints.
I personally preferred Cauldwell's Wiring a House (for Pros by Pros). In my opinion, Cauldwell's book focuses more on giving the information you will TRULY need to know to get a job done. I got much more out of the approximate 200 pages in Cauldwell's book than the 700 pages in Mullin's book. Cauldwell's book is better organized, more on point, and written in far clearer language. Further, while Cauldwell's book respects and presents the code, he takes it further by providing best practices ("above code") and also provides many helpful/practical hints.
To the extent you want a book that has every detail on the topic of residential electrical (such as a several paragraph explanation of why code uses the term "Luminaire" rather than "Light Fixture"), then this is a book for you. If you want a book that gives the information you need to get the majority of residential jobs done AND delivers this information in a manner that is concise and easy to understand... then I recommend a different book, such as Cauldwell's book noted above.
