I have looked in both the NEC and NFPA 72 (Fire Alarm Standard) but am unable to find the answer to this question: Does the low voltage wiring need to be included with the "current carrying conductors are to be 12" min above the ground"? It is my thought that they should be, but have had two answers, predictably yes and no. Any help and corresponding section numbers would be appreciated.
 
Thanks, Lee. Did you use seal tight and cast aluminum boxes? The reason I ask is I know if the system is speced that way it is permissable, but what about in an instance where the Fire Wire is ran w/o conduit and ran directly in to handi boxes chased directly to the check valve?
 
Yeah..that was my reaction too. But it was passed nonetheless. This is for self-education but also I just thought there were things that didn't look right and wanted to get another opinion.

This may have something to do with the fire pump controller, I believe there is a requirement that the bottom of the controller be at least 12" off the floor. It would make sense to do the same with associated wiring, but I cannot give a reference at this time.
 
cjnickjr- the 12" is right...and I would think that wiring even though it is fire wire still needs to be encased in conduit and any boxes that are in that area need to be weatherproof incase of flooding...just my thoughts. Is there a requirement for weatherproof installations below 12" in a fire pump room?
