What type of outlet is specified for installation near the appliance in attics?

The correct answer is that a receptacle outlet is specified for installation near appliances in attics. A receptacle outlet is designed to accept plugs from various devices, allowing appliances to be powered directly. This type of outlet provides flexibility in terms of connecting multiple appliances to a power source.

In attics, where there may be considerable heat and potential for moisture, it is vital to have outlets that can safely accommodate equipment. While grounded outlets and GFCI outlets are critical for ensuring safety in environments where shock hazards may be present, the term "receptacle outlet" encompasses a broader category, including these safety-focused designs.

The classification of a receptacle outlet applies to anything designed for plugging in a cord, and it ensures that users can apply appliances needed for specific tasks or maintenance in that space. Special purpose outlets are more restricted and designated for specific applications, which may not necessarily encompass general use around appliances.
