The Number 1 Practical, Portable, Plain-English Guide to the 2005 National Electrical Code
Whatever your role in designing or installing electrical systems, you need up-to-the-minute, easy-to-use information about the newest National Electrical Code. The Pocket Guide to the National Electrical Code®, 2005 Edition, brings together all the topics, tables, and calculations you'll use most often in a pocket guide organized for rapid access and maximum usability.
No other book is as convenient, or reflects as much feedback from working professionals. Writing in plain English, NFPA Committee Service Award honoree and Life Member Marvin J. Fischer, P.E., walks you through every key area of the code, highlighting crucial changes you need to know about. For more than twenty-two years the Pocket Guide has served as the quick, reliable source for Code answers. With even more up-to-date information--and a new lower price--this guide is a must-have for every practicing member in this field.
- Essential information for every electrician, contractor, installer, designer, inspector, architect, consultant, manufacturer, and instructor.
- Carry it anywhere--your shirt pocket, toolbox, glove compartment, briefcase...wherever you go!
- Covers general code issues and concepts; wiring and protection; wiring methods and materials; equipment for general use; special occupancies, equipment, and conditions; and communications systems.
- Also presents product safety standards, guidance on ampacity calculations, conduit and tubing fill tables, and administration/enforcement information.
- Contains virtually all the tables you'll need to use, and every calculation example.
- Organized to match the 2005 NEC itself, for easy reference and cross-checking.
- Reflects every significant change in the 2005 NEC.
