Masterplug WBX Weatherproof Electric Box for Outdoors (WBX-MS), Grey, 345 x 220 x 126.5 mm
Product description
If you’re wiring up something outdoors, weather protection stops being optional pretty quickly. This Masterplug WBX-MS weatherproof electric box is designed to help you get an external enclosure right, with a straightforward, practical shape for typical DIY and light electrical set-ups.
That said, it’s still just a box. Whether it’s the right choice depends on what you’re mounting inside and how you want to run cables, so it’s worth checking fit and access before you commit.
The essentials
The Masterplug WBX-MS is an outdoors-rated electric box in grey, built around the part number WBX-MS. The key headline is weatherproofing, which is the main reason people look at enclosures like this in the first place: to protect internal wiring components from rain, damp conditions and day-to-day exposure.
On paper, it’s a sensible buy if you want a dedicated outdoor housing rather than trying to improvise with an indoor enclosure and hoping for the best. The dimensions (345 x 220 x 126.5 mm) also suggest it’s aimed at setups where you need a bit more space than a tiny junction box.
It’s the kind of product you choose when you care about tidy cable management and you want the installation to look purposeful, not improvised.
What you’ll notice day to day
In real-world use, the difference between an outdoor enclosure and an indoor one is mostly about reliability and confidence. A weatherproof box like this is meant to keep the contents protected where the environment is less forgiving.
It’s also the kind of component that helps during installation: you’re able to plan where cables terminate, where connections sit, and how everything is housed behind a proper cover/box structure (as required for your setup).
Small limitation to keep in mind: the listing data you’ve provided doesn’t mention what exact accessories, cable entries, or cover details are included. So while the “weatherproof” concept is clear, your specific installation may still require you to source or confirm additional parts depending on how you’re wiring it.
Key points on choosing the right box
This is one of those purchases where “it looks right” isn’t enough. Before ordering, it helps to think through the practical checks:
- Space and fit: the external size is given, so compare it against the area you plan to mount it in.
- Your wiring layout: if your connections and components need a particular arrangement, make sure the internal space works for them.
- Outdoor readiness: weatherproofing is the point, but you’ll still want to ensure the rest of the installation (cable routes, sealing approach, and any mounting method) matches an outdoor situation.
- Colour and appearance: grey is included—handy if you’re trying to keep the finish neutral outdoors.
If you’re replacing an older outdoor box, the dimensions alone won’t always guarantee a straight swap, but they’ll get you a long way toward estimating compatibility.

Where it shines (and where it may not)
This Masterplug box makes the most sense if you want an outdoor enclosure with weatherproof intent and a decent amount of room for a practical wiring setup. It’s a strong pick for everyday situations such as housing outdoor connections in a more protected way—think garden/outbuilding electrics where you want the wiring contained rather than left exposed.
It might not be the best match if you’re working on an extremely compact install and don’t have space for a larger enclosure, because the dimensions are on the sizeable side for a standard “small” box. Also, if your project relies on specific entries or accessories that aren’t confirmed in the information available, you may find yourself needing extra components to complete the job.
FAQ
Is it only for outdoor use?
The product is explicitly described as weatherproof for outdoors, so that’s the primary intended setting.
What size is it?
The listed dimensions are 345 x 220 x 126.5 mm, so you can plan around that footprint.
Does the listing tell me what’s included?
The details provided here mention the box and its weatherproofing, but don’t list included accessories. If your install depends on specific parts (for example, fittings or cover-related items), it’s worth checking what comes in the pack.
Will it fit my existing installation?
It may, but you’ll need to compare both space and mounting approach. The dimensions help, but compatibility depends on how your current setup is routed and fixed.
Is it a good option for small DIY projects?
For the kind of DIY outdoor wiring jobs where you want containment and protection, it can be a practical choice. Just be mindful that outdoor electrics typically require careful planning and correct installation practices.
Buying verdict
It’s worth buying the Masterplug WBX-MS weatherproof electric box if you’re building or upgrading a weather-exposed outdoor wiring enclosure and you value a proper housing with the stated outdoor intent and generous dimensions.
You may want to skip it if your project needs a very small enclosure, or if you can’t confirm how your cable entry and required accessories will work with this specific box.
If you’re the sort of buyer who checks measurements, plans cable routes, and wants the install to look neat and protected, this fits that approach. If you’re looking for a plug-and-play solution without doing any fit checks, it could end up costing you time (or extra parts) later.
