Conduit that originates indoors but passes through or under a concrete slab is often subject to water infiltration. 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 and 6A cable from Hitachi Cable America eliminate the time and cost associated with transitioning from outdoor cable to indoor-rated cable.
