Ok just to update I carried out an "insulation resistance test "
across all cables and the lowest reading was between line and earth 545 meg at 500 volt so ok for now . Not sure what damage the water will do to the cable over time but just looks ruff to me .Thereis no mechanical protection where it leaves the conduit and goes into the duct. It's in one of those places that will probably be used as a store so a potential for the possible damage to the cable in the future.
