What must outdoor receptacles installed in wet locations have for additional protection?

Outdoor receptacles installed in wet locations need to have protective measures that safeguard against water ingress and potential electrical hazards. The most appropriate choice is the need for a weather-resistant cover.

A weather-resistant cover is designed to keep moisture out of the receptacle while still allowing for use even during rain or inclement weather. This feature is crucial because water and electricity can create very dangerous situations, leading to risks such as electrocution or equipment damage.

While ground fault circuit interrupters provide additional safety by disconnecting the circuit when they detect a ground fault, they do not specifically address the ingress of water into the receptacle itself. Similarly, having a GFCI-covered receptacle or extra duty outlet box hood could contribute to safety, but they do not ensure that the receptacle remains functional and protected from moisture in the same way that a weather-resistant cover does. Thus, utilizing a weather-resistant cover not only meets safety code requirements but also promotes reliable operation of outdoor electrical installations in wet conditions.
