What is the purpose of a junction box?

A junction box is specifically designed to protect and organize electrical connections and splices. It serves as an enclosure that houses wire connections, allowing for safe junctions between different electrical wires. This not only safeguards the connections from potential damage and exposure to outside elements but also helps to prevent accidental contact with live wires, which could lead to electrical shock or fires.

Additionally, junction boxes typically have covers that can be securely fastened, providing an added layer of protection and helping to maintain compliance with electrical codes. By consolidating connections within a single, accessible location, junction boxes simplify the installation and maintenance of electrical systems, making them an essential component in residential, commercial, and industrial wiring.
