These junction boxes are designed to be used when bringing two cables into a protected and weatherproof enclosure. This design provides a waterproof entry point for two cables, creating a neat and secure connection through the surface of the enclosure. They are commonly used in solar panel installations on 4WDs, caravans, RVs, boats and off-grid cabins.

A dual entry junction box provides a safe and weatherproof way to join, split, or extend electrical cables. With two cable entry points, it’s ideal for connecting solar panel leads, DC wiring, or other low-voltage circuits in a tidy and protected enclosure.
Yes. Most dual entry junction boxes are IP-rated for outdoor use, meaning they are resistant to dust, moisture, and UV exposure. They’re suitable for solar, marine, and off-grid applications where protection from the elements is essential.
Cable compatibility depends on the gland or entry size. These models accommodate cables between 4mm² and 6mm², but you should always check the product specifications to ensure your cables fit securely and maintain a watertight seal.
Ensure all connections are properly crimped or soldered, use appropriate gland seals for each entry point, and close the lid firmly to maintain weather resistance. If used in a solar or DC setup, always disconnect power before installation to prevent short circuits.
