According to the NEC, which of the following is generally not considered an outlet?

In electrical terms, an outlet is typically defined as a point in the electrical system where current is taken from the circuit, specifically for plugging in devices or appliances. A device box with a 3-way switch does not fulfill this definition, as a switch is primarily a controlling device that operates to allow or interrupt the flow of electricity rather than provide a connection point for electrical equipment.

The single-pole switch is also a device used for controlling the flow of electricity, much like the 3-way switch. However, it acts independently and does not serve as an outlet since it does not provide a point for plugging in appliances.

The four-way switch operates similarly to both the single-pole and the 3-way switch, allowing control of lights from multiple locations without serving as a direct outlet for devices.

In contrast, a duplex receptacle is an actual outlet; it provides two plug-in points for electrical devices, clearly meeting the definition of what an outlet is according to the NEC. Thus, it’s clear why the device box with a 3-way switch is not generally considered an outlet.
