One of the newest additions to Delmar's best-selling electrical line, Electrical Installation a Inspection uses comparative examples and step-by-step instructions to teach readers how to design and inspect electrical installations in a manner consistent the 2002 National Electrical Code (NECAr). The book begins with an introduction to basic electricity and proceeds, in logical order, through basic circuits and formulas to an examination of different types of electrical equipment and materials. Articles in the 2002 NECAr provide the framework for studying residential, commercial, and industrial electrical design applications. However, readers are urged to remember that an understanding of, and appreciation for, Code provisions is but a minimum requirement for a safe installation. Beyond qmeeting Code, q the author stresses the importance of electrical designs that meet end-user needs while also minimizing hazards inherent in the use of electrical energy.Figure 9-l2 shows an example of a single-phase, 2-wire transformer and a single- phase, 3-wire transformer. Figure 9-l3 shows an example of a delta-delta, 3-wire transformer, and a multi-phase transformer other than delta-delta, 3-wire.
