Some what familar with the appropriate articles in 760 and 300 which govern the use of NPLF in buildings (plenums,ceilings,ect,) and the cable substitution hierarchy. However I have seen were the cable specified being a typical NPLF UTP 18 awg. was used under ground (shed. 40 pvc) to monitor the OSY with tamper and flow devices. I suspect and have even used THWN in these cases, but the prints generally call for the SLC (signaling line circuits) to use the NPLF UTP.
So now with a specific job at hand with myself calling the shots, my question if i have not missed some thing, in order be to code compliant with NEC 70 NEC 72 the best answer would be the rated conductor for a wet location. The underlining assumption being standard off the shelf UTP or STP fire alarm and comm cable are not labeled or listed for wet locations.???? thank you for any input
