What's the difference between RHW and RHW-2 insulation?
What's the difference between RHW and RHW-2 insulation?
(OP)
Just poking around on US supplier websites it seems to me that the H indicates 75C and the HH indicates 90C. I also found where H indicates 75 C and the "2" indicates 90C. Then I ran into XHHW-2 and now I'm really confused. Anyone know?
