Basic Info.
Product Description
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.
CODES / STANDARDS
NMD90 cables meet or exceed the
following requirements:
CONSTRUCTION
ASTM
CSA C22.2 No. 48 (non-metallic sheathed cable)
Canadian Electrical Code1
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
