HEATEX® NMD90 (Red) is a variant of copper conductor CANADEX® NMD90, with NO WHITE WIRE in the 2 conductor cable. This cable is designed for use on 240-volt systems where there is no NEUTRAL, therefore the cable has a black and a red conductor in addition to the bare bonding wire. To make identification easier it is usually supplied with a RED overall jacket. It should NOT be used on 120 volt systems as there is no neutral, and it is dangerous to use either the red or the black as a neutral. Large sizes are available for use with electric furnaces.
