/ Field knowledge · NEC Article 100
“Outdoor rated” is not a location classification.
Dry: not normally subject to dampness or wetness. Damp: moderate moisture, no saturation. Wet: saturation or direct weather. Rainproof, raintight, weatherproof, and watertight are not interchangeable.
Rooftop HVAC, exterior disconnects, cooling towers, pumps, washdown, mechanical yards, below-grade, condensation. Classify the location before selecting the enclosure. A covered exterior is not automatically dry.
Source: Sparky #017 · tool: location check.
If the disconnect is outside and the enclosure is a guess
Send photos of the location and the nameplate if it exists. Masterbuild will say whether this is a damp/wet classification question or a replacement.
