What feature must outdoor non-locking receptacles of 20A, 125V typically have?

Outdoor non-locking receptacles of 20A, 125V are required to be weather-resistant to ensure safety and functionality in outdoor environments. Weather-resistant receptacles are designed to prevent moisture and debris from causing electrical failures or hazards, which is particularly important for outlets exposed to the elements.

Weather-resistance is a critical feature that helps protect the internal components of the receptacle from adverse weather conditions, such as rain, snow, and humidity. This design not only enhances the longevity of the receptacle but also helps to ensure that it remains safe for users, reducing the risk of electrical shock or short-circuits that could occur if water enters the outlet.

In contrast, while tamper-resistance and insulation are important features in certain electrical applications, they do not specifically address the challenges posed by outdoor use. Locking mechanisms, although beneficial in some contexts to prevent accidental disconnection or unauthorized access, are not a requirement for non-locking outdoor receptacles. Thus, the emphasis on weather-resistance is crucial for ensuring safe operation in outdoor settings.
