LAPP's Cable Range For Equipment Exports to USA
Lapp has announced a key addition to its ÖLFLEX M and TM cable ranges produced to meet the latest USA safety legislation for electrical equipment - NFPA 2007. The new ÖLFLEX CONTROL TM CY cable has a double screening of tinned copper wire braid and aluminium foil ensuring a high level of resistance against electrical interference. According to Lapp, the new cable is suitable for open or exposed runs on cable trays between equipment or devices and both on and in machines in industrial establishments in accordance to NEC 336.10(7).Matt
Before NFPA 2007, approvals provided generic Appliance Wiring Material (AWM) standards for use in specific, listed electrical equipment. This covered devices and appliances that are fully factory wired by their 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 frequently still employ 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). Non-compliance can lead to costly re-working or contractual penalties.
The new ÖLFLEX 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.
