We are planning to install data cabling in a retail store which will have some runs from the cash wrap in the middle of the store going through about 10'-20' of conduit in the slab before reaching a support beam where it will rise up to the ceiling joists to head back to the rack. According to the GC, the electrical contractor on site is stating the cable must be rated for a "wet location". I have not encountered this situation before and the only way I know to address this is to use burial cable, which seems like a ridiculous option which will cost the owner much additional expense, not to mention that the installed conduits may then not be large enough to accomodate. Can anyone offer any insight on this...doesn't seem right that this scenario should be deemed a "wet location" in the first place.
