What is NMWU wire used for? Underground electrical cable with copper electrical wire for underground electrical wiring. 14 AWG
American wire gauge
American wire gauge (AWG), also known as the Brown & Sharpe wire gauge, is a standardized wire gauge system used since 1857 predominantly in North America for the diameters of round, solid, nonferrous, electrically conducting wire. Dimensions of the wires are given in ASTM standard B 258. The cross-sectional area of each gauge is an important factor for determining its current-carrying cap…
What is NMWU cable used for?
Used for underground installations, including direct burial, and for wet and corrosive locations such as wet basements. Can be used at conductor temperatures not exceeding 60C. Southwire NMWU underground electrical cable is manufactured using annealed (soft) copper conductors.
Can Southwire's CSA-nwmu cables be used for direct burial?
Southwire's CSA-NWMU cables may be used for underground installations" including direct burial. It may also be used for environments exposed to the weather in dry and wet locations. The maximum allowable conductor temperature is 60°C.
How many conductors are in a CSA-nwmu cable?
Southwire's CSA-NWMU cables are available as two or three-conductor cables with a bare grounding conductor.
Does NMWU wire need to be in conduit?
This is installation method #1 - NMWU cable in Rigid PVC Conduit - one continuous cable running from the panelboard in the house to a junction box or panel installed in the garage. The cable is protected by PVC conduit on all exterior surfaces and for the entire underground section. Must be buried a minimum 18”.
What is NMWU wire?
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.
Can NMWU be used outdoors?
NMWU cable is primarily used for outside use from a distribution point. NMWU may be used in underground burial. NMWU temperatures may not exceed 90 degrees centigrade.
What is the voltage rating for NMWU cable?
300 voltsThe maximum voltage rating for all intended applications is 300 volts.
Can NMWU be direct buried?
14 AWG NMWU includes 2 copper wires and one ground wire. Used for underground installations, including direct burial, and for wet and corrosive locations such as wet basements. Can be used at conductor temperatures not exceeding 60C.
What wire is used for direct burial?
Common types of cables with a copper conductor suitable for direct burial are USE-2, UF-B Underground Feeder Cable, and Tracer Wire. Aluminum URD Direct Burial Wire is the most commonly used direct burial aluminum wire.
