Conduit that originates indoors but passes through or under a concrete slab is often subject to water infiltration. National Electric Code (NEC) 2017 Edition, Article 100 and the BICSI Telecommunication Distribution Methods Manual (TDMM) define these environments as wet locations since the slab and the associated conduit are subject to saturation by water. Standard plenum or riser rated cables can’t be used in these situations since water will have a catastrophic effect on both their electrical and physical performance. The typical solution has been to use outdoor cable in the conduit and then transition to the appropriately rated cable type once indoors. Drybit™ Category 6 cable from Proterial Cable America eliminates the time and cost associated with transitioning from outdoor cable to indoor-rated cable.
