Modern Commercial Wiring / Edition 7

by Harvey N. Holzman

Overview

Modern Commercial Wiring covers installation, maintenance, troubleshooting, and design. It provides instruction regarding the complex wiring requirements associated with commercial installations. Updated to the current National Electrical Code® (NEC), the text provides many opportunities for learning, researching, and applying the code. Specialized areas, such as motor control, emergency power systems, hazardous locations, and pool and fountain installations, are included.

• Updated to the 2017 National Electrical Code®, and many code references are made throughout the text.
• New for this edition: full-color photos and illustrations to more effectively engage today's students.
• Activities that familiarize students with using the NEC bring another element of real-world practice into the class.
• Chapters are arranged in a logical sequence but can be used independent of one another.
