Maximum temperature and humidity
January 31, 2006 @ 11:18 am
Q. What is the maximum use temperature and humidity for wiring duct?
A. Most PVC wiring duct is UL recognized up to a maximum use temperature of 50 C/122 F. Since PVC material is not hygroscopic, it should perform as intended at a humidity up to 80 percent. If the inside of the enclosure is going to have prolonged exposure to temperatures above 50 C/122 F, than it is recommended to use a wiring duct made from a Polyphenylene Oxide (PPO) material that is typically UL recognized for 95 C/203 F
