What is the function of a Junction Box?

The function of a junction box is to house electrical connections and protect them from damage. Junction boxes provide a safe and secure environment for electrical connections, ensuring that wires are insulated from moisture, physical stress, and accidental contact. By enclosing these connections, junction boxes help prevent electrical hazards, such as shorts or fires, that could occur if wires are exposed or improperly secured.

Additionally, junction boxes facilitate future maintenance or modifications to electrical systems; they allow easy access to connections for troubleshooting, repairs, or upgrades. This makes them an essential component of electrical systems, as they contribute to both safety and functionality.

While increasing voltage, serving as a conduit, or acting as a circuit breaker are important functions in electrical systems, they do not accurately describe the primary role of a junction box. Instead, the box's main purpose revolves around safeguarding electrical connections, which is why option B is the correct choice.
