The answer to 'how does junction box work' is a junction box is an electrical box used to connect and organize electrical wires. It provides a safe and accessible enclosure for splicing and terminating electrical circuits. Junction boxes are typically installed in walls, ceilings, or floors, and they allow for the connection of multiple cables or wires to a single point. This helps distribute power throughout a building and makes it easier to access and maintain the electrical system.
Junction boxes come in a variety of sizes and materials, such as metal or plastic, depending on the specific application and local electrical codes. They have openings or knockouts that allow cables and conduits to enter the box, and they are equipped with terminals or wire connectors to join the wires securely. Junction boxes also provide a way to access the electrical system for troubleshooting, repairs, or future modifications.
