Better homes and gardens step-by-step basic wiring (Better homes and gardens books)

To help you clear away any phobias or misunderstanding you might have about electrical principles, this book begins with a series of visual analogies that represent how household wiring works and how two vital safety systems protect against fire and shock. These drawings also introduce you to the primary electrical colors, black, white, and green-that enable you to decipher exactly what's going on at any point in your home's network of wires. Next we turn to those all-important repair jobs. Most of us feel some trepidation every time we remove the wall plate from a receptacle or drop a light fixture from the ceiling.
