Thanks again for the replies. I realize that 90 c is a high temp but these types of conductors are designed for use in high temp areas are they not? Like on a boiler or furnace or nuclear reactor?

Where in the heck would you use these conductors? Where would you install conductors like these where they would be accessible to personnel?

I was thinking that this is the maximum allowable temperature of the conductor BEFORE overheating not normal operating temp.
