BONAEVER 4-Way XL IP68 Junction Box

This waterproof junction box provides a four-way connection point rated for up to 40A and 450V. It is built for outdoor and underground installations where reliable cable joints are required. The PA66 nylon housing resists UV exposure, flame and corrosion across a working temperature range of -40 to 105 °C.

Cable Diameter and Terminal Checks

Verify that each cable falls within the 5 to 12 mm external diameter range and the 0.5 to 6.0 mm² cross-sectional area. The kit includes two sets of silicone sealing pads sized for 5 to 9 mm and 9 to 12 mm cables. Ensure the wiring board terminals accept the conductor size before sealing the enclosure.

Sustained Load and Environmental Performance

The IP68 rating is validated by a 4 metre water column test lasting 120 hours, confirming long-term submersion resistance. Integrated injection moulding and multiple silicone rings maintain sealing integrity under continuous thermal cycling. Flame-retardant PA66 nylon preserves structural stability during extended operation at the rated current.

Questions about this item

What cables and seals come inside the box, and do I need to buy any connectors separately?

The box includes two sets of silicone sealing pads for 5-9mm and 9-12mm cables; wire connectors for the 4-way terminal block are not supplied and must be purchased separately.

The listing shows one size — how do I know it will fit my 6.0mm² cables?

The terminal block accepts 0.5-6.0mm² conductors and the glands seal 5-12mm outer diameters, so a 6.0mm² cable with a matching sheath fits both specs.

The IP68 rating mentions 4 metres for 120 hours — what does that actually allow in a buried garden-light install?

It means the enclosure withstands continuous submersion at 4 m depth for 120 hours, so direct burial in wet soil or temporary flooding is within its tested limits.
