Application

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.

Standards:

Type NMD90 cable complies with:
ASTM
CSA C22.2 No. 48 (non-metallic sheathed cable)
Canadian Electrical Code1

construction

NMD90 cables are available as two- or three-conductor cables with a bare grounding conductor. It is manufactured using annealed (soft) copper conductors-compressed standing for stranded conductors; a heat-resistant thermoplastic polyvinyl chloride (PVC) insulation and nylon jacket for the individual conductors with a PVC jacket for the overall construction.
Conductors are white, black and red (for 3 conductor cables). Cable jackets are colour coded by size for quick identification in the Table below:

JACKET COLOUR CODE - Typical Application Guide
•WHITE - General Residential Wiring
•RED - 2 Black and Red conductors - 208V-240V Circuits (no neutral)
•ORANGE - No. 10 AWG General Residential Wiring
•YELLOW - No. 12 AWG General Residential Wiring
•BLUE - No. 14 AWG - 2 black and white conductors - 120V Arc Fault Circuit Interupter Applications
