Description

The new NFPA 79, the benchmark for industrial machinery safety, is aligned with the NEC® and NFPA 70E®. Advanced for new technologies and revised to correlate with the National Electrical Code® (NEC) and NFPA 70E: Standard for Electrical Safety in the Workplace®, the 2012 NFPA 79: Electrical Standard for Industrial Machinery spells out essential protection for operators, equipment, facilities, and work-in-progress. This edition presents the new best practices for the full spectrum of equipment — from single-motored drill presses to complex automated manufacturing systems. Critical changes in the 2012 NFPA 79 include: New definitions and revised rules for expanded wireless and cableless technology that align with IEC 60204-1 New sections in Chapters 6 and 16 recognizing deadly arc flash and stored energy hazards to protect workers and correlate with the 2012 NFPA 70E New rules for selecting overcurrent devices for motors, and the important addition of a 90 degree C temperature column to the conductor ampacity table. This Standard corresponds with the 2011 NEC. Addressing concerns from the field, a first-time section in Chapter 12 details conditions where Appliance Wiring Material (AWM) can be used as special cables with clarifications on determining suitability for use under specific conditions. Protect your facility and your workers with the latest safeguards. The 2012 NFPA 79 is a toolkit essential for safety managers, electrical designers, engineers, installers, owners, AHJs, and equipment manufacturers.
