Wet Location
An installation location subject to saturation with water or other liquids, including underground installations, concrete slabs in direct contact with earth, and outdoor locations exposed to weather.
Detailed Explanation
NEC Article 100 defines wet, damp, and dry locations, each with different wiring method requirements. In wet locations, conductors must have insulation rated for wet use (W designation, like THWN or XHHW). Boxes and fittings must be listed for wet locations. Underground installations are automatically considered wet locations. Proper equipment selection for wet locations prevents insulation degradation, corrosion, and ground faults.
