You are also likely to see ‘NMD’ with a number, such a NMD 7 or NMD 90. ‘NMD’ stands for ‘non-metallic dry‘. It means the jacket, or the sheathing, around the wire is not a metallic material and it’s for dry locations. Other types of wiring may have a metal sheathing or be rated for exterior and/or wet conditions.

What is NMD 90 wire?
Applications: NMD90 Canadian Copper Building wire is used to transmit power in construction sites and industrial areas. The electrical wire can be used in ceiling fixtures. Other common uses include lightweight power supply applications and exposed or concealed wiring in dry or wet areas.
What is NMD90 made of?
Aluminum Conductors
manufactures CSA approved aluminum NMD90. Cables are manufactured with three 8000 series aluminum ACM conductors insulated with RW90 cross-linked polyethylene rated at 300 volts from #8 to #2 AWG. The bonding conductor is bare aluminum. These cables are made identically to the copper based ones.
