Why prices for different colour junction box

[sham]

Ordering some junction boxes and the white 30A is cheaper than the Black one. Why ?. They are same brand and both three way.

depends on which downlights I'm fitting.

Sorry can you explain? I don't understand.

Reg.526.3 Every connection shall be accessible for inspection, testing & maintenance...

I know that, but that bit if wiring was already on connectors wrapped in tape. Anyway I went down it's lighting cables near a spot, so it is assesible. Put them in wago connections and Chuck box, so it can be pulled through the spot hole.
If it was not accessible I would prefer to use junction box. I don't feel yet, wago has been around long enough for me to trust them.

Bloody hell, never knew this. I like using 5A junction boxes for spot lights.

for spotlights you can use screw terminal junction boxes...You still can’t use the small junction boxes you’ve linked to for downlights because there is no strain relief . For downlights that you cant loop in and out of then you could use these Google Shopping - Product not found - https://www.google.com/shopping/product/1?q=hager+j501&safe=strict&client=safari&sa=X&hl=en-dz&biw=320&bih=454&tbs=vw:l,ss:53&prmd=simvn&prds=num:1,epd:5718562672038894077,paur:ClkAsKraXwwlQpciS9k11gYF510zIW6FMhq69hGjegV8lZ6b975okegQwahNBRJhBZNkUQOj02JO--9jQ7TsB2T6j1wow6vwWYsucrmt7LTc3cwqYnTICbULThIZAFPVH71wWdFXVMLrPIuokX7b_twLTWmyoA,prmr:1,pid:5718562672038894077,cs:1&ved=0ahUKEwj5zaP6n5PeAhXqAcAKHWCyCckQgjYI1AQ the reason you can use these is because they have a strain relief clamp and are accessible by pulling the down light out. Anything that’s not accessible then you need to use something like the J803 linked to earlier because they are labeled MF which is maintenance free. They are MF because of the push fit, constant pressure terminals.

The JB’s you’ve linked to are only really any good where they are accessible, can be screwed down and where you can clip the cables that enter them giving the required strain relief...One example could be for under cupboard lighting.

Have a trawl through that section of the regs sham, there are several solutions out there, eg if you dont like wagos you can use hager jbs.

Circular junction boxes are not and never have been deemed acceptable as a luminaire coupler.

Thank you, will do that.

Thank you all, for taking your time out to help me. Even though that was not my original question, but glad the conversation turned this way, been very informative.

You need to buy and carry with you some Hager j803 and j804

Great bits of kit. I'll add to that Wagoboxes and Wagobox light plus connectors, and a fistful of Click flow or similar never goes amiss.

I don't feel yet, wago has been around long enough for me to trust them.

Wagos have been around for decades. I used to come back from Germany with my suitcase full of them before they were on sale here. Also the continental style boxes, which I much prefer to the British Wagobox but are not certified MF because you have to provide your own glands if required.

The answer to your original question may be pigmentation. A lot of plastics are clear/white in the natural state, with other colours requiring pigment. Some of the additional cost could be due to pigments used to make the boxes black.

Just a point... in my opinion, it's only accessible if you know it's there, so if you can't see it when the job is finished I would consider it inaccessible. For anything else go for a maintenance free option like a Wagobox or the Hager boxes that have already been mentioned.

hit, nail and head spring to mind

I agree with sparkychick, it's the pigmentation sometimes. Years ago black cable-ties were quite noticeably dearer than the "natural" ones, and some still are, albeit a quick glance at a few suppliers show very little difference now, if any. Indeed, screwfix are listing 55 x 9mm packs of 100 at £1 more for the natural ones...
but I expect demand drives the prices more, nowadays.
