In what scenario can a weatherproof enclosure be utilized in a wet location without compromising safety?

When the receptacle is not attended
When it is used for portable equipment while attended
When the cover is always closed
When a GFCI is installed

The correct answer is: When it is used for portable equipment while attended

The utilization of a weatherproof enclosure in a wet location without compromising safety is effectively addressed when it is used for portable equipment while attended. This scenario is crucial because when the equipment is in use and being monitored by a person, immediate action can be taken if any issues arise, such as water intrusion or electrical faults. The attentive supervision helps ensure that any safety concerns are rectified in real-time, significantly reducing the risk of accidents or electrical hazards in a wet environment. Weatherproof enclosures are designed to protect against moisture, but during usage, the added layer of human oversight enhances safety measures. While other choices might suggest scenarios that seem plausible, they don't offer the same level of safety assurance. For instance, if a receptacle is not attended, risks are elevated as no one is there to manage potential hazards. Similarly, simply having the cover always closed does not guarantee safety due to possible degradation over time or improper sealing. While installing a GFCI provides additional protective measures, it is not a substitute for the attentiveness required when portable equipment is in use.
