4-2 CU NMD-90 RED JACKET W/G CSA 984 FT
Southwire #: 55772730
Application & Features
Southwire's Romex® SIMpull® 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 for two-conductor cables
and -10°C for three-conductor cables (with suitable handling procedures). Material should be properly stored above 0°C for 24 hours prior to installation. The maximum voltage rating for all intended applications is 300 volts. Consult the Canadian Electrical Code1 for further information related to applications.
