Product Details

Southwire Romex® Brand SIMpull® (nonmetallic-sheathed) cable may be used for both exposed and concealed work in dry locations with ampacity limited to that for 60 deg C conductors as specified in the National Electrical Code® (NEC). Individual conductor insulation is rated 90 deg C as required by the NEC and by the UL product standard (UL 719) for terminations in lighting fixtures. NM-B cable is primarily used in residential wiring as branch circuits for outlets, switches, and other loads. NM-B cable may be run in air voids of masonry block or tile walls where such walls are not wet or damp locations. Voltage rating for NM-B cable is 600 V. Individual conductors within Type NM-B cable are not listed or marked as THHN conductors (or any other NEC recognized conductor type) and are not permitted to be installed apart from the complete Type NM-B cable. Conductors routed inside panelboards and boxes (without the cable jacket) for termination therein are considered part of the complete Type NM-B cable.
