What is NMD90 Copper?
Non-metallic Sheathed Cable, 300V;
T90 Nylon or RW90 Insulation, PVC Jacket, Copper, Building Wire
NMD90 cables may be used for both exposed work in dry locations or concealed work in dry or damp
locations.The maximum allowable conductor temperature is 90°C. The minimum recommended installation
temperature is -25°C or -40°C for two-conductor cables and -25°C for three-conductor cables (with
