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 or BS6231 Cable.
[1]
Trirated Cable is so called because it meets the requirements of three different international standards: BS6231
[2], UL (or Underwriters Laboratories)
[3], and CSA (Canadian Standards Association).
[4] 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.
[5]
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 BS6231 states that the cable should have a maximum operating temperature of 90°C for continuous use.
[6]
Voltage rating is another area over which the different standards vary. UL
[7] and CSA
[8] give Trirated Cable a voltage rating of 600V, whilst it is rated at 1000V in the BS6231 standard.

with reagrds to your statement lenny, can you imagine looking at a chamber that is 10 years old, with the tape peeling away because of the heat? ive never used heat resistant tape, and have never seen others do it either. i strip back enough insulation for the lug, crimp it on, and use hellamans or heat shrink on the crimped part of the lug
