Which of the following is generally not considered an outlet by the NEC?

The reasoning behind identifying a device box with a 3-way switch as generally not being considered an outlet by the National Electrical Code (NEC) is rooted in the definitions established by the NEC for various electrical elements. An outlet is defined as a point in the wiring system at which current is taken to supply utilization equipment, such as electrical devices or appliances.

A device box with a 3-way switch serves a specific purpose, which is to control lighting or other devices from multiple locations, rather than providing a direct access point for plugging in equipment. While the switch itself is an essential component of the control circuit, it does not function as an outlet for consumers to connect electrical devices.

In contrast, the other options, such as an electrical panel, a GFCI outlet, and a smart home device, all fit the definition of outlets in that they allow for the connection and utilization of electrical current. An electrical panel distributes power to various circuits, a GFCI outlet provides a socket for plugging in electrical devices with added ground fault protection, and smart home devices, while they may not always be traditional outlets, often include outlet functionality as part of their design.
