If general-purpose circuits can contain receptacles, what else can they include?

General-purpose circuits are designed to supply power to various types of electrical devices and fixtures. When the question addresses what else can be included alongside receptacles in these circuits, lighting outlets are a logical addition. Lighting outlets are fixtures that provide illumination and are typically part of the same circuit that delivers power to receptacles.

In residential wiring, general-purpose circuits are often utilized to power not only outlets for appliances and devices but also to connect lighting fixtures and ceiling lights. This versatility is fundamental for both functionality and safety in residential settings. Therefore, including lighting outlets in general-purpose circuits makes practical sense, as it allows multiple types of electrical needs to be met under one circuit.

Other options, such as only ceiling fans or only floor lamps, are too specific and do not encompass the broader functionality of general-purpose circuits. Switches, while commonly associated with lighting outlets, do not represent an additional device for circuits on their own—they are merely a control mechanism rather than a load on the circuit. Thus, the inclusion of lighting outlets as an option aligns with the intent of general-purpose circuits, highlighting their utility in various applications.
