More Information 5 pole terminal block 10mm² wire capacity Size 15 x 15 x 5 cm IP66 dust and weatherproof rated Review: Durable outdoor junction boxes. - Solid, well built, weatherproof, been holding up well outdoors for spotlight installation. Review: Very good quality and very roomy - I needed an outdoor junction box as I have 4 cables coming out of wall, both electrical and network to go into a trunk underground. The box is absolutely the right size, not too big to look ugly and not too small that becomes tight inside for the number of cables/junctions I have. For my use it is the right size. It provides good options for cable entry through back, which what I needed. It is well marked, I used a drill to drill the right size hole in the back to allow all my cables in, I added a grommet myself (not included), then exit through 2 glands at the bottom. Worth noting that the 5 entry points (1 on top, 1 on each side and 2 on bottom do not require drilling, you can just push them out, only the back required using a drill). Everything worked well, no cracks no problem. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Masterplug | | Colour | Grey | | Finish type | Painted | | Material | Acrylonitrile Butadiene Styrene | | Product dimensions | 5D x 15W x 15H centimetres | | Style | Outdoor Weatherproof Junction Box, 5 Pole Terminal Block | ## Product Details - **Brand:** Masterplug - **Colour:** Grey - **Material:** Acrylonitrile Butadiene Styrene - **Product dimensions:** 5D x 15W x 15H centimetres - **Style:** Outdoor Weatherproof Junction Box, 5 Pole Terminal Block ## Images ![BG Electrical Outdoor Weatherproof Junction Box, 5 Pole Terminal Block - Image 1](https://m.media-amazon.com/images/I/71eQV5mXMhL.jpg) ![BG Electrical Outdoor Weatherproof Junction Box, 5 Pole Terminal Block - Image 2](https://m.media-amazon.com/images/I/61cEG8hRKUL.jpg) ![BG Electrical Outdoor Weatherproof Junction Box, 5 Pole Terminal Block - Image 3](https://m.media-amazon.com/images/I/81RvIXd1UKL.jpg) ![BG Electrical Outdoor Weatherproof Junction Box, 5 Pole Terminal Block - Image 4](https://m.media-amazon.com/images/I/61u6MDs-NSL.jpg) ![BG Electrical Outdoor Weatherproof Junction Box, 5 Pole Terminal Block - Image 5](https://m.media-amazon.com/images/I/61YUxnUFgNL.jpg) ## Questions & Answers **Q: I need an outdoor junction box for 12.9mm armoured cable. I see that the holes on this are M20; is there space to drill out to M22?** A: Hi, thank you for your product enquiry.The knock-outs are 20mm diameter as standard but also have provision to be drilled out to a maximum size of 25mm, so they would be suitable for your requirements. **Q: Are there terminal/conection points inside this junction box, Could really do with a picture of what's inside really.** A: Yes, there are terminal connectors inside the box. They are comprised of a (loose) strip of ordinary insulated connectors. It all works, 'though I would have preferred the connectors secured to the base of the box, like a junction box. **Q: For the junction box if a cable comes in through the back how do I make it waterproof for water running down the wall?** A: You can buy a Wiring Grommet Rubber https://www.amazon.co.uk/FIXMAN-255645-Rubber-Grommets-35pce/dp/B01MA6T2HD/ref=alp_dpwidget_a_w_?th=1&psc=1&smid=A3P5ROKL5A1OLE If you search enough you can buy individual. I would suggest you also use a circle of sealant around the box for extra precaution. **Q: What is the size of the recess to the lid? I want to mount a cctv camera with a 70mm dia base. The box will house the cables.** A: It should say in description ? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Durable outdoor junction boxes. *by L***R on 13 December 2025* Solid, well built, weatherproof, been holding up well outdoors for spotlight installation. ### ⭐⭐⭐⭐⭐ Very good quality and very roomy *by A***E on 13 November 2020* I needed an outdoor junction box as I have 4 cables coming out of wall, both electrical and network to go into a trunk underground. The box is absolutely the right size, not too big to look ugly and not too small that becomes tight inside for the number of cables/junctions I have. For my use it is the right size.

Everything worked well, no cracks no problem. ### ⭐⭐⭐⭐ Different brand supplied, but very good for the price. *by A***R on 1 November 2020* The box itself is very good, decent quality plastic, press-out knockouts (the one on the back is drill-out but that's fair), shrouded drain holes, grommets supplied for all fixing entries. It doesn't come with glands, but if you expected it to you should probably have called a sparky to do the job for you (especially as plenty of outdoor electrical jobs are in-scope for Part P). That said, the box I recieved was supplied with Masterplug rather than British General branding. BG and Masterplug are part of the same company/group, but in my experience the BG branded items are very high quality and mostly sold by trade suppliers, whereas Masterplug is the brand you'd find on the cheapest made-in-China extension lead in the Tesco homeware aisle. If I'd have known this, I might have shopped around first. All in it's great for the price, but the branding is worth bearing in mind if you were going to pay a premium for British General. ## Frequently Bought Together - Masterplug WPJB Outdoor Weatherproof Junction Box, 5 Pole Terminal Block, IP66 Rated, Grey - SWA Pack of 2 CW20S PACK-ALT Gland Packs Suitable for Outdoor Use, SWA Armoured Cables, Brass Cable Glands - BG Electrical Outdoor Double Switched Power Wall Plug Socket, Weatherproof, Nexus Storm, Grey, 13A, IP66 Rated, WP22 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/47927949-bg-electrical-outdoor-weatherproof-junction-box-5-pole-terminal-block](https://www.desertcart.tn/products/47927949-bg-electrical-outdoor-weatherproof-junction-box-5-pole-terminal-block) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-25*
