This 45th edition?part of a series continuously published for more than 80 years and based on the 2017 National Electrical Code?is a handy instruction manual that has been used by generations of readers who learn the ?why” as well as the ?how-to” of wiring practices. Encouraging readers to tackle jobs small and large, the guide covers everything from repairing a table lamp to wiring a whole house. After introducing the basics?standards, codes, safety practices, and an overview of how electricity is measured and delivered?chapters show how to design a layout for lights, switches, and receptacles; run a line from a utility pole; install wires, circuits, and grounds; and handle special projects such as replacing old wiring and wiring detached garages and accessory buildings. The do-it-yourselfer appreciates the detailed instructions and drawings, the homeowner working with a contractor gains insight into how to communicate with the professional about the problems to be solved, and students and teachers appreciate the range and depth of the subject matter and the accompanying student workbook.
