One of my biggest gripes is not being able to sleeve NM on the side of a house.. you must use UF cable..
Hv&Lv posted this link on another thread and it gives the specs for NM from Southwire.. http://www.southwire.com/products/Ro...TypeNMBOEM.htm
Southwire’s Romex® SIMpull® Type NM-B (non-metallic sheathed cable) may be used for both exposed and concealed work in normally dry locations at temperatures not to exceed 90°C (with ampacity limited to that for 60°C conductors) as specified in the National Electrical Code1 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. Voltage rating for NM-B cable is 600 volts.
IMO NM sleeved in PVC with sill plates caulked on both ends fits the description of "normally dry location" and "not subject to excessive moisture or dampness"..
So what do you guys think..
