Non-Metallic Sheathed Cable with Ground
Type NM-B (nonmetallic-sheathed cable) may be used for both exposed and concealed work in normally dry locations at temperatures not to exceed 90 degrees C (with ampacity limited to that for 60 degrees C conductors) as specified in the National Electrical Code 1
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 subject to excessive moisture or dampness
