Understanding NFPA 79Download Now
NFPA-79 is the electrical standard that has been developed by the National Fire Protection Association (NFPA) and is "intended to minimize the potential hazard of electrical shock and electrical fire hazards of industrial metalworking machine tools, woodworking machinery, plastics machinery and mass produced equipment, not portable by hand."
The National Fire Protection Association is also responsible for the National Electric Code (NEC)/ (NFPA-70).
The scope of NFPA-79 is summarized as follows: "The standard shall apply 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 to the machine."
One of the focuses of the latest edition is to improve product safety by ensuring that appropriate types of wire and cable are used in the application with regard to current carrying capacity, temperature rating, or flammability.
As such, the guidelines for NFPA-79 compliant products are more stringent than those cables allowed by past editions.
The NFPA-79 provisions make specific reference to only two types of cable.
