60 degrees C & PVC

[shortcircuit2]

Is PVC UL listed for a max temp. rating of 60 degrees C? If it is, are my wiring methods and circuit calculations installed in PVC restricted to 60 degrees C?

The following is from the UL Guide Information for "Rigid Non-Metallic Schedule 40 and Schedule 80 PVC Conduit" (DZYR)

Unless marked for higher temperature, rigid nonmetallic PVC conduit is intended for use with wire rated 75?C or less including where it is encased in concrete within buildings and where ambient temperature is 50?C or less. Where encased in concrete in trenches outside of buildings it is suitable for use with wires rated 90?C or less.

Thanks for the reply...I only ask because of this pdf. on Carlons website that I understood as it being 60 degrees C...

I'll research the White Book too...
