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

The reason a device box with a 3-way switch is not considered an outlet by the National Electrical Code (NEC) is that an outlet is defined specifically as a point in an electrical system at which current is taken to supply utilization equipment. In the context of the NEC, outlets are typically associated with devices like receptacles where power can be drawn, such as standard electrical sockets or ground fault circuit interrupters (GFCIs).

In contrast, a device box with a 3-way switch is designed to control the flow of electricity to light fixtures rather than providing a means for plugging in equipment. The primary function of a 3-way switch is to control lights from two different locations, making it integral to the lighting circuit but not an outlet in terms of providing accessible power for other devices.

Understanding this distinction is important for proper electrical installation and compliance with safety codes. While GFCIs and light switch outlets have roles in power distribution and safety, the 3-way switch serves a specific function in controlling lights, underscoring why it does not meet the criteria of an outlet.
