Tri-rated cable meets the requirements of three different international standards: BS 6231, UL 758, and CSA 22.2.
[1] Combining three standards in one product makes tri-rated cable suitable for use in equipment that is required to meet both North American and British wiring regulations.
[2] Tri-rated cables are constructed with a flexible stranded copper conductor (Class 5 according to IEC 60228), and insulation of heat resistant PVC.
Tri-rated cable is manufactured in a variety of insulation colours, including brown, orange, yellow, pink, and dark blue.
[citation needed] UL Style 1015 specifies wire sized from 28 to 9 AWG, with a maximum temperature of 105 °C, a voltage rating of 600 V, and PVC insulation with a thickness of 1⁄32 inch (0.8 mm).
