请教J大,dry/damp/wet跟indoor/outdoor,这两种概念之间是什么关系?

关于这三个概念,请参考如下:
Location, damp – an exterior or interior location that is normally or periodically subject to condensation
of moisture in, on, or adjacent to, electrical equipment, and includes partially protected locations.
Location, dry – a location not normally subject to dampness, but may include a location subject to
temporary dampness, as in the case of a building under construction, provided ventilation is adequate to
prevent an accumulation of moisture.
Location, wet – a location in which water or other liquid can drip, splash, or flow on or against electrical
equipment.
INDOOR USE – Use in an indoor location or where wet contact is not likely to occur.
