This can be a confusing topic. The issue usually arises in nuclear power plants because most cable is rated at 90 degrees C, but equipment terminals are rated for 60 or 75 degrees C. Getting this wrong leads to costly rework down the line. Continue reading “Cable ampacity – insulation temperature rating vs. equipment terminal ratings”
Cables can be purchased that are rated for different temperatures. The three most common conductor temperature ratings are 60ºC, 75ºC, and 90ºC . . . . Continue reading “Cable temperature ratings – it’s all about the insulation”
