What is a splice box used for?

A splice box, commonly referred to as a junction box, is primarily utilized to protect and house electrical splices. This is essential in electrical installations where multiple wires or cables need to be connected. The design of a splice box provides a safe environment for these connections, protecting them from environmental factors and physical damage, which helps to prevent short circuits and electrical hazards.

These boxes are typically made of materials that offer good electrical insulation and are suitable for various installation conditions, ensuring that the spliced connections remain secure and safe over time. Proper use of a splice box also allows for easier access for maintenance or future modifications to the wiring.

In contrast, other options like storing electrical tools, connecting multiple circuits, or enhancing wire insulation do not accurately describe the primary purpose of a splice box. While a splice box can facilitate connections between circuits indirectly, its core function is centered around housing and protecting splices, rather than altering the raw wiring or serving as a tool storage solution.
