What type of connector is used for the exterior conductors in the junction box description?

Metal connectors are typically used for exterior conductors in junction boxes due to their durability and resistance to environmental factors. Metal provides strong mechanical support and is much less susceptible to damage caused by exposure to sunlight, moisture, and temperature fluctuations compared to other materials. This ensures a reliable electrical connection, which is critical for maintaining safety and functionality in outdoor settings where exposure to elements is a concern.

In addition, metal connectors often provide a better ground connection, which is essential for protecting against electrical faults and ensuring the safety of electrical systems. They are designed to withstand certain stresses that occur in exterior applications, making them an appropriate choice for junction boxes used outdoors.

While other types of connectors may have their own advantages for specific applications, metal connectors stand out in scenarios requiring high strength and environmental resistance, thereby reinforcing their appropriateness for exterior conductors.
