In residential wiring, utility boxes are primarily used for what purpose?

Utility boxes, also known as junction boxes, serve a crucial role in residential wiring by facilitating safe electrical junctions. These boxes are designed to house electrical connections, protecting them from mechanical damage and preventing exposure to elements that could lead to short circuits or electrical fires. By enclosing wire connections within a box, the risk of accidental contact with live wires is minimized, thereby enhancing safety for both installers and occupants.

Furthermore, utility boxes provide a defined space for making wire splices and connections, ensuring that these aspects of the electrical system are neatly organized and compliant with the National Electrical Code (NEC). This organization not only aids in safety and functionality but also makes future troubleshooting or modifications to the electrical system easier.

While utility boxes might indirectly contribute to the aesthetics of a space by offering a cleaner installation, their primary purpose revolves around safety and organization in electrical wiring, which aligns perfectly with the correct choice.
