As an example, one of the largest U. With the new NFPA 79 edition, the primary focus is mainly one of overall safety and promoting further harmonization with its European counterpart Standard IEC These foreign wiring methods do not apply in the U.

The cables contained materials that were very fragile, which subsequently caused fires resulting in several million dollars in liability and damage. Five years later, many issues remained unresolved and the fallout from this recall is ongoing.

Perhaps one of the most overlooked items regarding the installation of equipment and machines in an industrial or commercial setting is selection of the proper cable. This could be due to expenses surrounding the original purchase price of machines, equipment, and mounting hardware conduits, trays, racewaysplus labor costs necessary to complete the installation.

This involved reorganizing the NFPA 79 chapter structure to follow IEC and to agree with less restrictive, more progressive requirements without sacrificing equipment safety.

Today, with the ever-increasing prevalence of eleftrical and insurance liability issues, proper cable specification is more important than ever.

No longer was the use of AWM allowed; if used, an unanticipated on-site inspection could result in a shutdown.

Unfortunately, this can prove to be very costly to the building contractor, machine fabricator, manufacturing occupant, and all others involved in the process. That being said, the acceptability of AWM required a thorough review of the standard because the allowance was not automatic. In addition, overseas manufacturers sometimes include European or Asian cables along with their machines, further complicating the nfpa 79 electrical standard for industrial machinery 2012 edition selection issue.

One of the major changes in the update involved cable selection options required under section If the requirements were not followed, or deemed noncompliant by the inspection authority, serious repercussions could occur. Many industry participants considered this change unrealistic, and it was soon realized that further modification was necessary. Intentional or not, cable selection seems to be given a secondary degree of attention in the installation process.

Some examples of industrial machinery include machine tools, injection molding machines, woodworking equipment, assembling machinery, material handling machinery and inspection and eddition machines. Another issue is that manufacturers may use low-cost materials with thin insulation to provide a lucrative cable price for the end user.

Take the edotion back and replace it with a new one recallor replace the faulty cables and be billed for the material and labor. In the long run, nfpa 79 electrical standard for industrial machinery 2012 edition substandard cables must be replaced.

As there are different codes and regulatory requirements that affect machine electrical installations both in the U. Specifically, NFPA 79 applies to the electrical equipment used within a wide variety of machines — and groups of machines npfa working together in a coordinated manner.

Machine manufacturers are generally given two options when their products fail in end use:
