The concept of this book is that of a personal tool, which compacts 20 percent of the data that is needed 80 percent of the time by electrical design professionals in the preliminary design of buildings of all types and sizes. This second edition of the Electrical Engineer’s Portable Handbook includes a number of significant updates and a few worthy additions and enhancements. Two major changes throughout the latest edition of the (NEC) are the system of nomenclature/paragraphing hierarchy and the metrication of units as primary in tables and data.
This book is unique among handbooks. It provides myriad valuable time-saving data for the experienced practitioner, yet there are enough concept explanations and examples on critical topics to use it as a teaching tool for the fledgling electrical design professional. Also, the topics of Chapters 3 through 7, in particular, are arranged in a sequence that closely approximates the normal design process flow to facilitate speed.

Chapter #03 contains updated motor circuit feeder schedules, a transformer primary and secondary feeder schedule, and a new table of three phase, three-wire, and four-wire plus ground feeder schedules sized to the over current protection rating. These should prove to be time-saving tools.
Chapter #0
4 has been updated and an introductory
overview of a dissipation array system (DAS) for lightning protection has been
added. This is an emerging technology application of a long-known theory that
is gaining popularity in some critical installations.
Telecommunications-structured
cabling systems information in Chapter #08 has been completely replaced with the latest BICSI
standards (including tables, diagrams, and illustrations). An introductory
overview to blown optical fiber technology (BOFT) provides insight into this
very interesting, cost-competitive, and extremely flexible optical fiber
technology. It is particularly amenable to renovation/retrofit applications
because of its flexibility and avoids initial capitalization for installing
future capacity in new construction.
Building codes and laws, new technologies, and materials are ever changing
in this industry. Therefore, this book should be viewed as a starter of simple data collection that
must be updated over time. New
editions may be published in the future.
