Description

This rugged 3 way IP68 junction box by Securicam is designed for heavy-duty outdoor electrical connections in the UK. Its flame-retardant ABS enclosure and silicone grommets create a dust-tight, submersible seal (IP68), protecting cable splices in all weather (rain, frost, UV). Inside, a 4-pole screw-clamp terminal block makes wiring easy without soldering. The box is CE‐marked and RoHS‐compliant for EU standards and carries UKCA certification for Britain. Common applications for 3 Way IP68 Junction Box include garden/landscape lighting, CCTV cameras, fountain pumps, and other outdoor power splits.

Specifications of 3 Way IP68 Junction Box:

Feature Specification
Dimensions (L×W×H) ~111x88x36 mm (outer) & 72x70x27 mm (inner); compact design yet The large model supports robust wiring.
Cable entry (Ø) 3 PG-19 cable glands (M20/M25) with rubber seals for Ø 4–15 mm conductors (supplied seals: 4–9 mm, 9–12 mm, 12–15 mm). 6 pcs screws & 1 pcs PA10-4P connector.
Enclosure material High-impact, flame-retardant ABS plastic (black, UV-stable). The tough housing resists corrosion and ensures a long outdoor life.
Ingress protection IP68 (dust-tight; continuous immersion proof, per EN 60529). Rated for use in heavy rain, underground or submerged applications without leakage.
Terminal type Internal 4‑pole screw‐clamp terminal block (accepts 0.5–6.0 mm² wire). Solid screw terminals (500 V/50 A rating) simplify wiring and ensure secure connections.
Operating temp. –40 °C to +105 °C. Suitable for UK freeze–thaw cycles up to very hot summer sun conditions.
Mounting Surface‑mount via three pre‑melded flanges (holes for screws). Allows sturdy fixing to walls or mounting surfaces; install vertically or horizontally as needed.
Certifications CE and RoHS (meets EU safety/environment standards); UKCA mark (UK Conformity Assessed, per UK regulations). Also meets relevant BS/EN enclosure standards.
Colour Matte black (provides low visibility outdoors). UV-stable finish prevents fading/embrittlement in sun exposure.
Weight ≈0.115 kg (lightweight for easy installation but sturdy construction).
Use cases Outdoor wiring splices in gardens, landscaping, and street lighting; ideal for CCTV system power splits, fountain/pump connectors, solar panel branches, and any weather‐exposed electrical junction. Ensures safe, dry connections for LED lights, security cameras, pumps, etc., in UK outdoor environments.

Each specification above is based on manufacturer and industry data. This 3 way IP68 junction box is optimised for UK outdoor use – it keeps rain and dust out while meeting British/EU electrical safety codes. Its large internal terminal block and included glands make installation quick and secure, whether by professional electricians or savvy DIYers.

FAQs

What exactly does “IP68” mean — can I fully submerge this junction box?
IP68 means dust-tight and designed to survive immersion in water, but the exact depth and time depend on the manufacturer—don’t assume “ocean-proof” unless the seller states a depth/time. In practice IP68 implies much stronger protection than everyday splash-proof ratings, but you should check the product’s specific immersion test (e.g., 1 m for 30 min is a common baseline; some products are tested deeper or longer).
My cables are thin — will the 4–15 mm spec work for smaller wires? How do I seal them?
Yes—the “4–15 mm” range is the usual usable range because these boxes include interchangeable rubber grommet inserts (silicone/sleeves) that take up the slack and form a water-tight seal around smaller cables. If you have much thinner conductors, use the smallest grommet insert supplied, or add a small inner sleeve/heat-shrink plus silicone to ensure a snug fit. Always test the seal after installation.
How do I wire a 3-way IP68 junction box — is there a terminal block inside?
Most 3-way IP68 boxes come with a screw terminal block (often 3- or 4-pole) or removable connector inside. Typical wiring steps: strip the conductors to the recommended length, insert into the correct terminal, tighten the screw firmly (but don’t over-torque), close the lid and ensure the gasket seats fully, then tighten the outer caps/glands. Watch polarity for DC/LED runs and test with a multimeter before final burial or immersion. There are many short video demos showing the exact steps for these connector blocks.
Can I use a 3-way IP68 junction box for mains voltage (household supply)? What is the voltage/current rating?
Some models are rated for mains, but ratings vary. Typical listings show terminal ratings like 24 A/41 A and voltage ratings up to ~450 V for certain products— check the specific item’s datasheet before using on mains. If you’re wiring household mains, follow the local electrical code and, when in doubt, have a licensed electrician sign off. Never rely on the IP rating alone to prove suitability for a particular voltage or installation environment.
Can these boxes be buried underground or left permanently underwater?
IP68 indicates that these products are resistant to immersion, and some sellers specifically state that their boxes can be buried or used at depths of several meters underwater (up to 3 meters in certain product listings). Important: manufacturers define the exact submersion depth/time and whether burial/long-term immersion is covered by their test. If you need permanent underwater or in-ground use, choose a product whose spec sheet explicitly lists that use and follow installation guidance (e.g., correct cable gland seating, no sharp edges on cables).
What should I check when choosing/installing one (materials, temp, mounting, life)?
Look for material (UV-stable polycarbonate or PA9 to avoid cracking), temperature rating (T-rating like T85 for hot environments), whether it includes multiple grommet sizes, the terminal type (reusable/removable vs. glued), and the stated IP68 test conditions (depth/time). Installation tips: don’t overtighten glands, avoid bending or stressing the cable where it enters, re-check gaskets after thermal cycles, and test with a multimeter and a water test (if practical) before finalising. If you need help picking a model, a buying guide for IP68 junction boxes is a useful place to start.
