The primary purpose of a junction box in electrical systems is to connect electrical wires safely. Junction boxes provide a protective enclosure for wire connections, ensuring that they are safe from physical damage and environmental factors. In a typical installation, multiple wires are joined within the junction box, which allows for the distribution of power to various circuits while also keeping the connections accessible for maintenance or inspection. The box helps prevent any potential hazards associated with exposed wires, such as short circuits or electrical fires.

Additionally, junction boxes can facilitate the organization of electrical connections, making it easier to troubleshoot electrical issues when they arise.
