This informative introduction to the NEC provides electrical engineers, both professionals and students, with invaluable insight to customary building codes. Written by the Executive Director of Standards and Safety of the NECA, H. Brooke Stauffer offers a comprehensive description of the NEC and commonly encountered building codes when designing a building's electrical subsystems. The Engineer's Guide to the National Electrical Code steers beginning electrical engineers through the complex regulations of the NEC in a clear and accessible way.
The modernization of industrial power systems has been stifled by industry's acceptance of extremely outdated practices. Industry is hesitant to depart from power system design practices influenced by the economic concerns and technology of the post World War II period. In order to break free of outdated techniques and ensure product quality and continuity of operations, engineers must apply novel techniques to plan, design, and implement electrical power systems. Based on the author's 40 years of experience in Industry, Industrial Power Systems illustrates the importance of reliable power systems and provides engineers the tools to plan, design, and implement one. Using materials from IEEE courses developed for practicing engineers, the book covers relevant engineering features and modern design procedures, including power system studies, grounding, instrument transformers, and medium-voltage motors. The author provides a number of practical tables, including IEEE and European standards, and design principles for industrial applications. Long overdue, Industrial Power Systems provides power engineers with a blueprint for designing electrical systems that will provide continuously available electric power at the quality and quantity needed to maintain operations and standards of production.
Starting from the basics of a power distribution system, the author explained the mechanism of how grounding noise currents arise in a facility transformer. This is followed by computer simulation of short circuit or fault currents required in sizing the interrupting capacity of a circuit breaker. Chapter 3 closely examines propagation constant and characteristic impedance of a transmission line. The model of a transmission line can explain most of the electrical or electronics problems. Some of these problems include redundancy in power systems, and grounding noise voltage. Often, an engineer needs to find the cause of a failure in a system. He must have, at his disposal, a systematic method of testing to find the most probable cause of failure. This book recommends the boundary approach in finding such a cause. Testing may involve characterizing a device or a signal. An example of how an unknown device may be characterized is shown in this book. In this book, a grounding noise voltage is treated as a signal. It is, perhaps, the most common cause of failures in electronic systems. To illustrate an example of how a signal may be characterized and address grounding itself, Chapter 7 shows experiments on how a grounding noise voltage may be minimized. Finally, Chapter 8 is a recommended approach in designing a grounding system.
This book provides an understanding of the nature of short-circuit currents, current interruption theories, circuit breaker types, calculations according to ANSI/IEEE and IEC standards, theoretical and practical basis of short-circuit current sources, and the rating structure of switching devices. The book aims to explain the nature of short-circuit currents, the symmetrical components for unsymmetrical faults, and matrix methods of solutions, which are invariably used on digital computers. It includes innovations, worked examples, case studies, and solved problems.

Information is provided for selecting the proper circuit breaker for a particular application. This recommended practice helps the application engineer specify the type of circuit breaker, ratings, trip functions, accessories, acceptance tests, and maintenance requirements. It also discusses circuit breakers for special applications, e.g., instantaneous only and switches. In addition, it provides information for applying circuit breakers at different locations in the power system, and for protecting specific components. Guidelines are also given for coordinating combinations of line-side and load-side devices.
