Electrical Systems: Residential and Commercial Wiring

Comprehensive and detailed, this reference presents the critical revisions in technical topics driven by emerging technology and building-code changes. Starting with a basic overview of the National Electrical Code and its enforcement, this handbook reviews the theory and practice of installing electrical wiring. The guidelines provide an essential context for understanding the major industry segments--residential, farm, commercial, and industrial--and the techniques that help to prevent or solve all wiring problems. A wealth of tips and handy tricks offered in a professional, down-to-earth style make this a favorite on-the-job resource. Professional practitioners, students and apprentices, and those seeking more information on performing electrical work at home will find everything they need to know about the wiring trade in this handy volume.

Spend your study time wisely As you advance from student to apprentice to journeyman status, you log a lot of study hours. Make the most of those hours with this fully updated, sharply focused self-study course. It contains everything you need to know about electrical theory and applications, clearly defined and logically organized, with illustrations for clarity and review questions at the end of each chapter to help you test your knowledge. * Understand electron theory and how electricity affects matter * Recognize applications for both alternating and direct current * Comprehend Ohm's Law and the laws governing magnetic circuits * Learn from detailed drawings and diagrams * Explore trigonometry and alternative methods of calculation * Identify instruments and measurements used in electrical applications * Apply proper grounding and ground testing, insulation testing, and power factor correction

The concept and detailed design of buildings requires a comprehensive approach. Coordinating the different trades is one of the architect's key tasks. In view of the fact that electrical installations in buildings are becoming increasingly complex, the architect needs to have a solid, basic understanding in this field in order to be able to prepare the design for the input of the specialist engineers. However, most architects find it hard to understand anything but the basic concepts of electrical engineering, in spite of the fact that it is an increasingly important field in view of the complexity of modern buildings. As an intermediary between all parties involved in the construction project, the architect must be able to understand electrical engineering concepts in buildings and competently advise his clients. BASICS Electrical Installations conveys the basic concepts of electrical installations in buildings in practical applications. Selection of subjects covered: Power supply Design of electrical installations Power supply systems and mains lines Distribution boards Forms of installation Wiring layouts Slots and recesses Information technology Lightning protection systems
