Product Information

Full details

The Wessex Electrical Junction Box (115 x 115 x 55mm) is an essential component for electricians and DIY enthusiasts needing a secure, weather-resistant enclosure for wiring connections. Its primary benefit is the IP66 ingress protection rating, which ensures that internal circuits remain shielded from dust and powerful water jets, making it highly reliable for outdoor use. However, users should note that while it features easy-access knockouts, it does not include pre-installed cable glands, meaning you will need to supply your own waterproof seals to maintain the IP66 rating during installation.

FAQs

Is this box suitable for underwater use?

No, it is IP66 rated, which means it is protected against powerful water jets but is not designed for submersion.

Can I paint the exterior of the box?

Yes, it is possible to paint the exterior, but ensure the paint is suitable for plastic surfaces and does not enter the seal area.

Does this box come with terminal blocks inside?

No, the box is provided as an empty enclosure to allow for custom wiring configurations.

What is the maximum cable size I can use?

The maximum size depends on the cable glands you choose to install; please verify the clamping range of your specific glands.

Is the box UV resistant?

The materials are designed for outdoor use and handle typical solar exposure well, though prolonged extreme UV may affect plastic over many years.

Are the mounting screws included?

The package includes the lid screws, but wall-mounting screws for attaching the box to the building surface are typically not included.

Troubleshooting

Water detected inside the box

Check that all cable glands are tightened correctly and that the lid gasket is properly seated and free of debris.

Difficulty pushing out knockouts

Use a small, flat-head screwdriver and a gentle tap with a hammer to break the seal along the pre-scored lines.

Lid does not sit flush

Ensure no internal wires are caught between the lid and the base and confirm all four corner screws are tightened evenly.

Pros and Cons

Pros

High IP66 rating ensures excellent weatherproofing
Compact and versatile sizing for various wiring setups
Simple installation via push-out knockouts
Suitable for both indoor and outdoor environments

Cons

Cable glands not included in the package
Rigid casing requires precise drilling for non-standard cable sizes
Lid screws must be tightened evenly to maintain the waterproof seal

Setup, Compatibility & Care

To install, mark the mounting points on the rear of the box and secure it to the mounting surface using appropriate wall plugs and screws. When preparing the entries, use the push-out knockouts for your cabling. Crucial: To maintain the IP66 weatherproofing, you must use cable glands rated at IP66 or higher at every entry point. Do not leave unused knockouts open. For maintenance, periodically inspect the lid seal for signs of cracking or debris. Clean the exterior with a damp cloth, avoiding abrasive chemicals that could degrade the housing material over time.
