Recreational Vehicle (RV) Technician Practice Test

What type of covers are required on all AC receptacles located outside?

1. Weatherproof covers

2. Wet location covers

3. Dust covers

4. Standard covers

The correct answer is: Wet location covers

The requirement for wet location covers on all AC receptacles located outside is based on safety standards that aim to protect electrical equipment from moisture and other environmental elements. Wet location covers are specifically designed to provide a secure enclosure against rain, snow, and splashing water, ensuring that water does not enter the receptacle and cause short circuits or electrical shock hazards. Using wet location covers helps to maintain the integrity of the electrical connections and reduce the risk of failure or hazards caused by water exposure. These types of covers are essential for any outdoor application where the receptacles are likely to be exposed to moisture. They often feature gaskets and secure closures to enhance their protective qualities, making them suitable for areas that experience heavy rains or direct water exposure. While weatherproof covers might seem like a reasonable choice, they are not specifically rated for conditions that involve direct water exposure. Dust covers provide basic protection but do not address moisture issues, and standard covers do not provide the necessary sealing to prevent water ingress. Therefore, the correct choice focuses on the need for complete protection against water, which is why wet location covers are mandated in these scenarios.
