Lighting fixtures intended for wet locations must be marked in what way?

Lighting fixtures intended for wet locations must be marked as "suitable for wet locations." This labeling is crucial because it informs the installer and the end user that the fixture has been specifically designed and tested to operate safely in environments where it may be exposed to moisture, water, or other forms of humidity. Such fixtures are built with materials and components that can withstand these conditions without causing electrical failures, corrosion, or safety hazards.

The importance of this marking cannot be overstated, especially in residential wiring where improper installation of lighting fixtures in inappropriate locations can lead to short circuits, electrical shocks, or even fire hazards. By ensuring that a fixture displays the suitable markings, it guarantees that all safety standards have been met for those types of environments. Thus, the correct identification is vital to maintaining safety and compliance with electrical codes.
