evening all,

im after a few pointers, could somebody suggest a decent box that can be buried under ground, im looking to install some bollard type fittings in the back garden on top of flags. im thinking of SWA in and out, flex up through flag into bollard.





cheers
 
Personally I would fit a 20mm y box in the bollard. Don't like the idea of a flex buried and then passing through a flag stone.

I did type a lovely reply, but the forum did it's usual trick of timing out on me, so I'm not typing it all again...
One word..Hi-tuff

I'd agree, Hi-tuff is good for this application if unlikely to be mechanically damaged. I'd try to get all the terminations above ground if at all possible, even if that means choosing a different bollard light.

Buried boxes with connection in a nightmare, avoid unless you use an expensive insulating jell/compound.
 
Why not try a swa through joint buried with flex out one side as well through a conduit up to the fitting? I did this on a job when we had about 15 led up lighters per circuit to light up a tree. :-/
 
Here's a job I did recently using swa glanded into 20mm trouser boxes

Then bollard bolted on top

Pratley boxes are designed for underground use and seem to work quite well (though expensive), but I agree with others, keep joints above ground if possible.

I too have not heard them called trouser boxes, but certainly from that picture it looks appropriate.

Most of our street lighting is jointed underground, and is not an issue, Good quality jointing kit using potting compound will outlast the swa.
 
Now, if only you'd protected the sheathing from the sharp edges of the concrete, I'd have been really impressed... ;)

Lol I had filed the edges with a rasp which made them smooth lol I suppose I could have used some conduit to protect the cable further lol

all the customer was worried about was that I had set the slabs correctly facing north lol I had my compass out and everything lol
