Specification

12/3 NMWU Copper Building Wire

Allowable Ampacity for 12/3 NMWU Copper Building Wire: 20 Amps

Applications:

NMWU stands for non-metallic wet underground direct burial wire. It is suitable for wet and dry conditions as long as the electrical cable is not exposed to mechanical damage. NMWU can be used as exposed wiring in complicated weather conditions. The electrical wire is perfect for direct earth burial as long as the protections required by authorities are met.

NMWU Copper Building Wire has a minimum temperature of - 25°C (except for three-conductor cables at -10°C) with suitable handling procedures. The maximum temperature of NMWU Copper Building Wire is estimated at 60°C. The wire has a 300V rating.

Also Known As:

NMWU Copper Construction Wire, NMWU, NMWU Cable, Non-Metallic Wet Underground Direct Burial Wire, NMWU Underground Wire, NMWU Direct Burial Wire, NMWU Conduit Wire, NMWU Non Metallic Wet Underground Direct Burial Wire.

Standards:

• CSA Spec. C22.2 No. 48-M90
• CSA FT 1

Construction:

Conductors:

The wire has three copper conductors. The cables also have a bonding ground conductor. In cables sized between 10 AWG and 6 AWG, the bonding conductor is made of bare solid copper. In cables sized between 4 AWG and 2 AWG, the bonding conductor is made of bare compact round concentric lay class “B” stranded copper.

Insulation:

The cable has cross-linked polyethylene NMD90 insulation available in black, white, or red colors.

Jacket:

An FT1 PVC black jacket protects the wire from sunlight and harsh weather conditions.
