How to choose a weatherproof enclosure

A weatherproof enclosure lets you use standard or modular accessories in places they could not otherwise go: garden walls, driveways, car ports, farm buildings and commercial exteriors. The right box depends on what goes inside, the IP rating needed and how cables will enter.

Types of enclosure

1 gang and 2 gang empty boxes: Zahler IP66 boxes that accept suitable accessories behind a sealed lid
Universal accessory box: the Selectric heavy duty IP66 2 gang box for a wide choice of accessories
Modular enclosures: Gewiss IP55 enclosures in 3 module (99x82x55mm) and 4 module (132x82x55mm) sizes for modular switches and sockets

Key things to check

Confirm that the accessory you plan to fit is compatible with the box in size and depth, with room for cable bends. Choose IP66 for exposed walls and IP55 for more sheltered areas. Check whether the lid allows a plug to stay inserted with the cover closed. Plan cable entries carefully and use suitable glands or grommets so the rating is maintained. Colour may matter too: black boxes blend with dark cladding and fencing, while grey suits render and stone.

Installation and compliance

Fix enclosures to a flat, solid surface so the seal sits evenly, and mount them with entries facing down. Do not drill extra holes in the body unless the manufacturer allows it. Outdoor socket circuits need RCD protection under current wiring regulations (BS 7671), and cables to remote locations often need SWA armoured cable. For larger distribution or junction needs, see our galvanised and PVC enclosures.

FAQ's Ask Your Own Question

Can I put a standard indoor socket inside a weatherproof enclosure?: Often yes, as that is what many empty weatherproof boxes are designed for, provided the socket is compatible with the box's size and fixings and the enclosure keeps its IP rating when closed. Check the manufacturer's list of compatible accessories and the depth needed. The installation still needs RCD protection and must follow current wiring regulations for outdoor use.
What is the difference between an IP55 and IP66 enclosure?: IP55 enclosures are dust-protected and resist low-pressure water jets, while IP66 enclosures are fully dust-tight and resist powerful water jets. IP66 is the better choice for exposed walls, farms, yards and coastal locations. IP55 is often enough for sheltered positions such as under a canopy or inside a damp outbuilding.
What is a modular weatherproof enclosure used for?: A modular enclosure holds a combination of modular devices, such as switches and sockets, in one sealed housing. It is useful where several controls are needed together outdoors, for example a light switch beside a socket on a patio or in a workshop. Modules must come from the same system as the enclosure to fit correctly and keep the IP rating.
How do I keep the IP rating when adding cable entries?: Use the knockouts or entry points provided and seal each one with a gland or grommet sized for the cable. Avoid drilling new holes unless the manufacturer allows it, and use the right tool so the edges stay clean. Seal any unused openings and check that the lid gasket is seated properly before closing the enclosure.
Are weatherproof enclosures UV resistant?: Most outdoor enclosures are made from polycarbonate or similar plastics intended for exterior use, but UV resistance varies between products. Check the manufacturer's information if the box will face direct sunlight for long periods. Where possible, mount enclosures in a sheltered position to reduce exposure to sun, rain and impact.
Can I mount an outdoor enclosure on a fence post?: Yes, provided the post is solid and securely fixed, and the enclosure is mounted flat so the seal sits evenly. Supply cables to fence posts and garden features normally need mechanical protection, such as SWA armoured cable, and should be routed to avoid damage from digging. Follow current wiring regulations and the manufacturer's instructions for fixing and cable entry.
