Ultimate Guide: Wiring demystifies residential electrical systems through easy-to-understand language and the use of step-by-step photography and detailed illustrations. Homeowners will learn how their home's electrical system works and how to complete installations and repairs themselves. This project-based book shows how to select the right cable, wires, and other equipment and how to run wiring through walls and between floors. Projects guide the reader through installing switches, outlet receptacles, electrical appliances, and lighting systems. The book also shows how outdoor lighting, including security and low-voltage systems, can help homeowners improve and illuminate the exterior areas around their homes. As with previous editions, the seventh edition has been updated to comply with the latest National Electrical Code.
