What is the main function of a junction box?

• A. To provide lighting control
• B. To protect electrical connections
• C. To act as a power distributor
• D. To house circuit breakers

Answer: (B)

The primary function of a junction box is to protect electrical connections. Junction boxes are designed to house and safeguard the electrical connections made between wires. This enclosure serves multiple purposes: it prevents accidental contact with live wires, reduces the risk of short circuits and electrical fires, and helps to keep the connections safe from damage and environmental factors, such as moisture or dust. In essence, the junction box creates a safe environment for wire splices or connections, thereby promoting the longevity and reliability of the electrical system. While junction boxes can play a role in housing circuit breakers or facilitating power distribution by connecting multiple circuits, their fundamental role is to ensure safety and protection of those electrical connections.
