Suitable Junction Box for Outdoor Use

IfInDoubtDIY · Wednesday at 9:52 PM

I’m planning a DIY job replacing some floodlights that no longer work. Part of the job will involve replacing the Twin & Earth cable that has been incorrectly used outdoors with suitable black 3 core flex.

The light connections use wall mounted JBs like this one:

The knockouts haven’t even been replaced with glands, just drilled and wires pushed through.

Am I correct in thinking that the JB shown above is not correct for outdoor use and should be replaced with something like this?

Using suitable glands in the above, of course!

The Vimark box in the first link requires to be fitted with appropriate glands. The same is true for the BG box.
Neither box is particularly weather proof, IP44 and 55 respectively. A Wiska box would be a better choice.

The first linked junction boxes are awful, the rubber gland things on them are pure garbage.

AIUI These have been used outside quite successfully.

Wiska boxes with proper cable glands is the ideal choice

Thanks @Murdochcat - I’ve been reading about these since @Taylortwocities and @mattylad mentioned them and they definitely appear to be what I want. Mrs IfInDoubtDIY is not happy that the lights have stopped working and she believes (as I do) that they were never installed properly, and she says she wants me to do it properly so I think Wiska with glands is what I’m going to use!
