What is the purpose of a junction box in electrical wiring?

The purpose of a junction box in electrical wiring is to house wire connections and protect electrical connections from damage. Junction boxes provide a safe and secure location to make electrical splices and connections, safeguarding them from external elements that could cause wear or deterioration. They also ensure that wiring is accessible for future maintenance or upgrades while keeping it organized and compliant with building codes. By enclosing the connections, junction boxes help to prevent accidental contact with live wires, thereby enhancing overall safety in an electrical system. This function is vital as it reduces the risk of electrical faults, potential fires, and ensures the reliability of the electrical installation.
