Book Description
An apparatus for testing a ground fault circuit interrupt device includes a processor, an input device connected to the processor for receiving input from an operator, a storage media connected to the processor for storing test data, an output device connected to the processor for outputting information corresponding to the test data to the operator, and a calibrated variable load circuit connected between the processor and the ground fault circuit interrupt device. The ground fault circuit interrupt device is configured to trip a corresponding circuit breaker. The processor is configured to receive signals from the calibrated variable load circuit and to process the signals to determine a trip threshold current and/or a trip time. A method of testing the ground fault circuit interrupt device includes a first step of providing an identification for the ground fault circuit interrupt device. Test data is then recorded in accordance with the identification. By comparing test data from an initial test with test data from a subsequent test, a trend of performance for the ground fault circuit interrupt device is determined.

Book Description
Safe, efficient, code-compliant electrical installations are made simple with the latest publication of this widely popular resource. Like its highly successful previous editions, the National Electrical Code? 2011 LOOSE LEAF combines solid, thorough, research-based content with the tools you need to build an in-depth understanding of the most important topics. It provides the full text of the updated Code regulations alongside expert commentary from code specialists, offering code rationale, clarifications for new and updated rules, and practical, real-world advice on how to apply the code. And in a loose-leaf format, it's easy to customize your experience with the Code by adding job- and situation- specific materials. New to the 2011 edition are articles including first-time Article 399 on October, Overhead Conductors with over 600 volts, first-time Article 694 on Small Wind Electric Systems, first-time Article 840 on Premises Powered Broadband Communications Systems, and more. This winning combination has created a valuable reference for those in or entering careers in electrical design, installation, inspection, and safety.

Book Description
This book seeks to explain in simple terms the behavior of fault current through the general mass of earth, the origin of short circuit current and its value, and how a circuit breaker operates. The drawings are unique and allow the reader to visualize the behavior of a fault current. The book clarifies common myths pertaining to a grounding electrode, short circuit, and opens neutral conditions, and provides an unambiguous understanding of the theoretical and practical explanation for an effective earthing and protective system in electrical installations. There are numerous grounding problems and unexplained fault conditions in electrical circuitry that are taken for granted and left unattended for extended periods. Potential voltage can be found on the earthing conductors in processing plants, refineries, and other industrial plants. A combination of topics in this book addresses problems that have been adversely affecting the electrical industry for years. There are a number of systems in the electrical industry that are common in the workplace but are not understood by the average workman who has to work with these systems daily. Systems such as ungrounded systems, clean earthing systems, motor controls, resistance grounding, lightning protection systems, and Intra earthing systems are all common systems; however, the knowledge base of these systems is very limited. This book highlights the basics of these topics and gives a working overview of these systems. The book also discusses the principle of operation of the ground fault circuit interrupter (GFCI). It is expected that the information provided will allow the reader to visualize various types of GFCIs and the principle of operation without necessarily having to revert to other text.

Book Description
Only half of a home inspector's challenge is technical-- the other half is effective communication with clients. This text is designed both for beginners who need an in- depth introduction and more advanced practitioners looking for tips, sample dialogue and documents, and an understanding of the scope and ethical aspects of a home inspection. The text includes "Inspection Checklists that summarize the important components and problems home inspectors will encounter, and can be used for actual inspections.
