What does Article 110.12 require for the installation of electrical equipment in damp or wet locations?

Article 110.12 of the National Electrical Code (NEC) focuses on the suitability of electrical equipment for its intended environment, particularly in damp or wet locations. This article highlights the necessity for equipment to be specifically designed and rated for the environmental conditions it will face.

When equipment is placed in damp or wet conditions, it must be able to withstand moisture and potential corrosion that can occur. This ensures not just operational safety but also the longevity and reliability of the equipment. By requiring that the equipment is suitable for these specific conditions, the NEC aims to mitigate risks such as electrical shock, equipment failure, and fire hazards that could arise from inappropriate equipment choice in such environments.

The other options do not fully encompass the broader requirement of suitability for the environmental conditions. For instance, being low-voltage rated, having insulation rated for humidity, or being double insulated are all characteristics that might contribute to the overall suitability, but they are not comprehensive enough on their own to meet the requirements laid out in Article 110.12 regarding environmental suitability.
