UL 758

UL 758 covers Appliance Wiring Material (AWM)

UL 758 Standard covers the requirements for Appliance Wiring Material (AWM) in the form of single insulated conductors, multi-conductor cables, optical fibres, individually insulated conductors, and fibre optic members for use as components in multi-conductor cables. However, Tratos mainly use it in the context of single-core AWM as one of the three National Standards to which the popular Tri-rated cables are manufactured.

UL 758 Standard covers appliance wiring material with operating temperatures from a minimum 60°C (140°F) dry temperature rating and voltage ratings from a minimum 30-volt rating. Conductor size ranges from 50 AWG to 2000 kcmil. Appliance wiring materials (AWM) composed entirely of optical fibre members or electrical conductors in combination with optical fibre members are also covered by these requirements.
However, it does not cover the optical performance of any optical-fibre member or group of such members.

The AWM covered by UL 758 Standard are solely for use as factory-installed wiring either within the overall enclosure of appliances and other equipment (internal wiring) or as external interconnecting cable for appliances (external wiring), or for further processing as components in multi-conductor cables.

The final acceptance of AWM is dependent upon its use in complete equipment that conforms with the standards applicable to such equipment.
