Best JB to bury - driveway lights

[richo106]

Hi

I am looking to install some driveway up lights on my new drive way, either side of my drive is grass/gravel (soft dig)

I have spoke to a couple sparky mates and they have done it with galv conduit t boxes, wagos and magic gel (or similar) with gaskets/box lids. SWA between the boxes and flex out to driveway. Then bury these boxes to the side of the driveway so they aren’t on show, I know not ideal but no where else to put JB’s

My question is, is there a better way to do this? What’s the best thing to bury? Wiska box? Galv conduit box?

Any advice/ information greatly appreciated

Many Thanks

None of what you suggest are suitable for burial get some proper joint kits.

I think he will need tee joints (break out) rather than straight, but same place, same style of thing.

It must be a Resin filled enclosure no matter what form

I agree.

Galv boxes will corrode although terminations should be secure if encased in resin, but the resin filled joint kit per Julie #3 is the best option.

Thank you for the replies, I am going to look for a resin T joint.

Could I just fill wiska box’s with resin? And use wago connectors. As there will be 2 x SWA’s and flex

Thanks again

[westward10]

There are two ways of doing this the right way and the wrong way.

 

[DefyG]

Whichever way you decide, don’t forget to ensure swa has continuity and is earthed.

Are you contemplating using mains or 12 volts ?

Not really relevant.

How long is the cable run /how many lights ?

However good your joints are (and there’s some good suggestions above), it won’t matter unless those lights have incredibly good drainage around them. They are almost certain to let water in sooner or later imo in the real world.

You want ip68, which usually means ELV. Look at Collingwood. Much more money, but I personally wouldn’t fit that Aurora fitting. Learnt my lesson the hard way years ago.

They’d probably be ok in raised decking, anything else, forget it.

Maybe ELV would be worth him looking at.

How will this affect the cable joints.

You can use junction hubs etc.

Not sure what a junction hub is but are these suitable for burial and how is the voltage relevant.

 

[DefyG]

Probably means those little T shaped connectors that come with the ELV 'Kits'.
I wouldn't have thought they should be buried though.

1. Safety – 12 volts is inherently safe for children and pets
2. A bigger range of good quality, smaller fittings to choose from.
3. Easier installation of cables in borders and planting – flexible cables to spike spotlights can be several times longer than to 240 volt garden lights and you can move them around more easily.
4. A better range of lamps to choose from which are brighter, whiter, more efficient and longer lasting than their 240 volt cousins. Some 12 volt lamps are twice as efficient as their 240 volt equivalents.
5. If you have an accident with a low voltage cable it is usually easier to fix.
6. Low voltage transformers and power supplies absorb transients such as those caused when a lamp blows and are, to a degree, tolerant of earth currents arising from a bit of damp in light fittings. A little bit of dampness might not affect a 12 volt circuit but it could render a 240 volt circuit unusable.

You can use flexible cables, HI-Tuffs of similar length for their installation rather than armoured, and you don’t need to bury the cables approximately 600mm, as you do with LV installations.

1. Regulations do not consider children or pets?
2. 12v have a larger range?
3. Why is installation easier, quote a Regulation.
5. 12v is not low voltage but 230v is??

And yes in some instances the term low voltage is wrong.

Well in all instances you are incorrect. It may be more professional if you quoted from personal knowledge and not some online resource.

I am incorrect or the site is incorrect ?

If you are quoting the site then the site is incorrect, 12v is elv.

As I said at #18

If the OP can use ELV that would imo be the way to go.

It's safer, easier, and he could probably do it himself.

How does using elv change the type of buried connection.
