What is the purpose of a junction box?

The primary purpose of a junction box is to protect electrical connections and splices. Junction boxes are designed to house and safeguard electrical junctions where wires connect. This protection is essential for preventing electrical shock, short circuits, and fire hazards that could result from exposed wires or poor connections. By enclosing these connections, junction boxes also help to keep out dust, moisture, and other environmental factors that could potentially damage the wiring over time. Proper installation of junction boxes is important for maintaining the safety and integrity of an electrical system, ensuring that all connections remain secure and protected from external elements.
