What type of electrical installation must meet strict moisture standards?

Bathroom installations must meet strict moisture standards due to the specific conditions present in these environments. Bathrooms are areas where water is frequently used, which increases the risk of moisture-related issues like corrosion, short circuits, and electrical shock. To mitigate these hazards, the National Electrical Code (NEC) and other safety standards impose regulations that dictate the appropriate materials, lighting fixtures, and installation techniques to be used in bathrooms. This includes the use of weatherproof or moisture-resistant fixtures, covers, and wiring techniques that help ensure safety and reliability in wet conditions.

In contrast, while outdoor installations and commercial kitchens may also face moisture concerns, they have different requirements and are not subject to the same stringent regulations specifically for moisture as bathroom installations. Residential lighting is generally not exposed to high moisture levels, so it does not have the same strict standards related to moisture.
