Just so you know where I was at prior to reading this book I did not know how to change an outlet or switch but I was capable of changing a lightbulb. Last week after reading this book and watching 5 or 6 YouTube-How-To video's I was able by myself to 1) pull the old knob-and-tube wiring in a 100 year old house I am flipping, 2) completely rewire it, 3) ground it, 4) install a new breaker panel, 5) add 11 outlets, 6) add 3 3-way switches, 7) 12 canned lights and 8) add a 30amp outlet for a dryer - without getting electrocuted (I did shock myself pretty good twice)
More amazing, I did it in the span of a week after I got home from work. I'm bragging, sure, but then when I was done, I passed the City electrical inspection the first time!
I'm sure being a licensed Electrician is better than just reading this book... I guess. I got bids for the above work at $9000-$12000 from some of those guys. But if I factor in the cost of this book which I bought at Home Depot plus the cost of materials and also paid my self $100 an hour including the hours spent reading the book, well then it cost me $4000!
Check back with me in 6 months and we'll see if the house has burnt down.
WARNING: I am in no way condoning or encouraging do-it-yourself electrical work. Working with electricity CAN KILL YOU. You should always seek the help of a licensed and experienced electrician for any and all electrical work.
SECOND WARNING: No, now that I am professing to be as good or better than a licensed professional, I will not come and help you with the electrical work in your house. Nor will I give you free advice that you should be getting from a licensed electrician... I mean, now that I'm paying myself $100 an hour... I don't have time for that.
I recommend like the author does that you read this book cover to cover. Understanding how electricity works, is measured and moved really makes a difference once you start working with it. This book delivers that in a very easy to understand format. As a reference when your in and doing the work the book is a fantastic companion too. I also really appreciated the parts when the author would describe how to do something to code and then mention something like "If you're going to be doing this in a barn here is a "different" but safe way you could do it." Which generally meant easier and/or cheaper.
5 Stars seems weird to give a book like this because I didn't love reading it or look forward to the next chapter like all my other 5 star books. For what it is though and what I needed it for, it is perfect, so 5 stars.
