Electrical wiring keeps the power flowing through your home. It is run to power lighting, outlets, and devices throughout your home including appliances. Some wiring is low-voltage for things such as doorbells, while other wiring is much larger for large loads to power things such as ovens, ranges, welders, sub-panels, wells, and air conditioners. This book explains residential electrical systems in easy-to-understand terms to help you learn how to work with electric wiring and repair, replace, and install typical electrical-system elements.
