DESCRIPTION
CSA File #LL23462 Class 5821 02
NMD90 (Red) HEATEX® is a variant of copper conductor NMD90 CANADEX®, 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.
Application
For open or concealed wiring in dry or damp locations where not exposed to mechanical injury.
Minimum recommended handling temperature minus 25°C (with suitable handling procedures).
Maximum conductor temperature 90°C.
Specifically designed for 240 V heating circuits.
