Right-angled connectors are the first ever to rotate to ensure ease of connection.
This covered devices and appliances that are fully factory wired by the manufacturer.
AWM standards were not intended to cover wiring carried out in the field for connecting of equipment and installations.
As AWM-recognised cables could only be used for the specific applications listed in their individual type description, installers have frequently employed incorrect cables.
The new edition of NFPA 79 expressly forbids the usage of UL Recognised AWM in industrial machinery.
Only equipment wired with listed cables, suitable for its intended application, will now be allowed.
For electrical and industrial plant engineering companies, changes must be made now for development, planning and production of all new equipment.
The new standard includes an exception where AWM approved cable may continue to be used as part of a listed assembly "as an integral part of a fully factory wired ready-made wired sensor or actuator", or if it has been evaluated for external use.
Should these exceptions be sought it is recommended that they should be authorised by the National Recognised Testing Laboratories (NTRL) or Authority Having Jurisdiction (AH).
Noncompliance can lead to costly reworking or contractual penalties.
The new Olflex M and TM listed cables from Lapp offer fully compliant alternatives to the old AWM cables, allowing complete flexibility and security of use for products to be exported to the USA.
Matt Ansell, Marketing Manager of Lapp Group UK, comments: "Our new NFPA 79 listed cables are intended for use in electrical equipment and as fixed wiring in buildings used for residential, commercial and industrial purposes".
"They can also be used as flexible connecting leads for movable electrical equipment, simplifying cable selection and logistics for our customers".
"The use of such listed cables and wires must comply with the relevant articles of the National Electrical Coding (NEC)".
