After talking to NFPA and a few others, I going to have to yield to the majority on the use of NM cable for PLFA wiring on the secondary side of the power source. Boy it's tough to type these words. I am only hanging on to one thread of victory in that the specs on the FACP and the specs for the system would have the last call. That being said, baring any restrictions, one could use NM or UF cable for the PLFA system.
