NFPA 79, Electrical Standard for Industrial Machinery, is about to be released as the new 2012 edition in October. Available for pre-order now from Document Center Inc., the 93-page Standard applies to the electrical/electronic equipment, apparatus, or systems of industrial machines operating from a nominal voltage of 600 volts or less, and commencing at the point of connection of the supply to the electrical equipment of the machine.
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.
NFPA 79 does not include the additional requirements for machines intended for use in hazardous (classified) locations.
The 2012 NFPA 79 is a toolkit essential for safety managers, electrical designers, engineers, installers, owners, AHJs, and equipment manufacturers.
