What is the purpose of junction boxes?

Junction boxes serve a critical function in electrical systems, primarily designed to protect and house electrical connections. They provide a safe enclosure for wires and connections, ensuring that any splices or connections are shielded from environmental factors, damage, and accidental contact. This protection helps to prevent electrical hazards, such as short circuits or fire risk, by minimizing the exposure of wiring and connections to moisture, dust, and physical interference.

In addition to protection, junction boxes facilitate the organization of wiring within a building, allowing for easier access for maintenance and troubleshooting. They also help in meeting electrical codes and standards, which often mandate the use of junction boxes in certain installations to ensure safety and compliance. Overall, the proper use of junction boxes is crucial for maintaining a safe and efficient electrical system.
