Term Main definition
Trirated

Trirated Cable is a high temperature, flame retardant electrical cable designed for use in panel building. Trirated Cable
is often referred to more generally as Panel Wire, T.R.S (tri-rated singles) or BS 6231 Cable.

Trirated Cable is so called because it meets the requirements of three different international standards: The British Standards Institute (BSi) BS 6231, UL (or Underwriters Laboratories), and CSA (Canadian Standards Association). Combining three international standards in one product, makes Trirated Cable suitable for use in equipment required to meet both North American and European wiring regulations.

This single core cable is described as ‘high temperature cable’ because of the high temperatures to which it is subjected
during the manufacturing process. According to the UL standard, the maximum operating temperature of Trirated Cable is 105
°C. This refers, however, to operating temperature for a specific length of time. The British Standard BS 6231 states that
the cable should have a maximum operating temperature of 90 °C for continuous use.

Voltage rating is another area over which the different standards vary. UL and CSA give Trirated Cable a voltage rating of
600 V, whilst it is rated at 1000 V in the BS 6231 standard.
