About This

Waterproof Design: 3-port junction box with 4-position 40A screw terminals (450V AC). Compatible with 20-10 AWG wires (0.5-6mm²). IP68-rated enclosure withstands submersion up to 4 meters for 120 hours. Compact size (2.79" x 2.2" x 1.15"(L*W*H) horizontal/vertical installation. Full kit includes box, terminals, screwdriver, and 9 waterproof rubber rings.
Premium Materials & Durability: PA66 nylon housing and silicone seals resist aging and extreme temperatures (-40°F to 221°F). Nickel-plated pure copper terminals prevent corrosion, suitable for coastal, mining, or underground use. UV-resistant to prevent cracking or fading.
Waterproofing & Versatility: Triple-sealed design ensures protection against heavy rain and temporary submersion. Perfect for garden lights, solar panels, pool LED strips, and holiday decorations. (Tip: For prolonged underwater submersion exceeding IP68 requirements, professional epoxy potting is recommended to ensure.)
3-Step Installation：WARNING: Always de-energize circuits before operation! 1. De-energize and Verify: Disconnect the power source and verify no live current using appropriate testing equipment. 2. Prep & Terminate Wires: a. Loosen the box nut; align the O-ring (critical for seal). b. Strip 20-10 AWG wires to 0.61±0.02 inches (15.5±0.5mm). c. Insert wire into terminal (min. depth 0.35 inches/9 mm). 3. Finalize Installation: Tighten terminal screws to specified torque; seal enclosure using the provided screwdriver.
Wide Applications: Industrial projects (LED billboards, tunnel lights, solar water heaters, wind turbines) and home DIY (Halloween props, Christmas lights, patio lighting). Reliable solution for all outdoor and harsh environment wiring needs.
