14/2 NMWU Copper Building Wire Allowable Ampacity for 14/2 NMWU Copper Building Wire: 15 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 Canadian 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 Canadian Copper Building Wire is estimated at 60°C. The wire has a 300V rating. Also Known As: NMWU Canadian 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 two 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. Specifications: Size AWG: 14 Number of Conductors: 2 Weight: 88 lbs per 1000 ft Overall Diameter: 0.244 x 0.492 inches Insulation: PVC Features: Rated 300 volts. Meets CSA Spec. C22.2 No. 48-M90 Has minimum temperature of - 25°C (except for 3 conductor cables at minus 10°C) with suitable handling procedures Also a maximum conductor temperature of 60 degrees Celsius. Direct ground burial. Wiring protection exposed to the weather. for Category 1 and 2 locations (Ref. CE Code Part 1 Section 22) including barns, stables, etc. For open and concealed wiring in wet or dry locations where not exposed to mechanical injury.
