The most essential quality to appreciate about electricity is that the typical amount that flows through the wires in your home can be fatal if you contact it directly. Sources estimate that there are about 50,000 electrical fires each year causing 450 deaths, 1,500 injuries, and 1.3 billion dollars in property damage. Home wiring can be a very satisfying task for do‑it‑yourselfers, but if you don’t know what you’re doing or are in any way uncomfortable with the idea of working around electricity, do not attempt it. This chapter explains the fundamental principles behind the electrical circuits that run through our homes. It also includes some basic tips for working safely with wiring, and it introduces you to the essential tools you’ll need for the job. The beginner should consider it mandatory reading. Even if you have a good grasp of electrical principles, take some time to review the material. A refresher course is always useful.
