## Description

Masterplug WBX-MS Weatherproof Electric Box for Outdoors, 345 x 220 x 126.5 mm, Grey : desertcart.co.uk: DIY & Tools

Review: Bone dry after 6 weeks - Works well if used properly. Really simple to use provided you respect its limits and use it responsibly. Used over Christmas as a junction box to put an old extension lead in. Plenty of room for transformers plugged into a 4g splitter and the sturdy plastic construction and decent seals have kept it bone dry over the last 5 weeks. Top product, bargain.
Review: Excellent replacement for ageing power box. - Bought to replace ageing box of same make which has weathered badly and no longer water tight. Ideal replacement where previous installation has cable and socket so just swapping casing. Easy to use and provides good connectivity. Ideal for Xmas lights etc. If you require cable and connector block you need to buy next model up also on desertcart. I would recommend.

## Questions & Answers

**Q: Size on website is wrong can you confirm size?**
A: Interior dimensions are: 32.5cm x 21cm x 8cm.

**Q: Do you put a normal indoor extension lead inside and then plug outdoor lights in. How many plugs does it take?**
A: The socket end of your extension lead fits inside the box and it would accommodate up to 4 sockets providing your plugs are standard 3pin and not RCD type.

**Q: I need something safe and waterproof to charge mobility scooter overnight outside? Is this ok for that?**
A: Very good I bought 4 of them for outside christmas lights ans have already used them for lights at a birthday

**Q: Can i use a normal indoor extention lead and use the box to use it outside or do i need an outdoor exatention lead too?**
A: Well, the box is certainly a weatherproof enclosure so long as you feed the flex cable through the rubber holes and make sure that the clamp is firmly in place afterwards.  Therefore an indoor extension lead would be OK and you can rest the socket part within the box.  The plug socket in the house must be RCD protected.  I would recommend mounting/fixing the box on something solid outdoors.  Also you will need to protect the outdoor section of the flex cable from damage.
