According to the NEC, what are considered "wet locations"?

Wet locations, as defined by the National Electrical Code (NEC), are spaces that are directly exposed to moisture or water. This includes areas where water can accumulate or places where high levels of moisture are prevalent, such as outdoor installations, bathrooms, and locations that might be subject to rain or splashing water. The definition is relevant for determining proper installation practices and the types of electrical equipment that can be safely used in these environments.

Understanding this classification helps in ensuring that electrical installations are adequate for the conditions they will encounter, thereby minimizing safety risks such as electric shock or equipment failure. The focus on moisture exposure is essential for compliance with the NEC standards, as it guides the selection of suitable wiring and protective measures.

The other options do not accurately reflect the NEC's definition of wet locations. Dry storage areas and basements typically don’t have the degree of exposure to moisture required to be classified as wet. Indoor areas without windows may lack natural light, but they do not necessarily imply moisture exposure. Locations with high humidity can have varied conditions, but do not always qualify as wet without actual water exposure.
