Which type of receptacles require GFCI protection in wet locations?

The correct choice identifies that all 125V, single-phase, 15 and 30A receptacles require Ground Fault Circuit Interrupter (GFCI) protection in wet locations, as specified by the National Electrical Code (NEC). This requirement is crucial for enhancing safety in areas that are exposed to moisture or are otherwise at risk of water exposure, such as locations outdoors, in basements, kitchens, and bathrooms.

GFCI devices are designed to quickly cut off electrical power if they detect an imbalance in the electrical current, which is critical in preventing electric shock in such environments. By focusing on both 15A and 30A receptacles, the answer acknowledges that not only general-purpose outlet configurations require GFCI protection but also specific higher-rated receptacles that may be utilized in certain wet conditions.

In contrast, specifying only outdoor receptacles or limiting the requirement to just 125V, 15A receptacles neglects the broad scope of receptacle applications susceptible to moisture. Additionally, stating that all types of receptacles need GFCI protection is overly inclusive, as certain types of receptacles may not be subject to the same wet location guidelines. Focusing on the correct voltage and amp rating for receptacles provides clarity
