Extending wiring to a ceiling rose

I have been replacing a ceiling light in a bedroom and there is not enough slack in the electric cable to connect to the new light. I'm assuming, from what I've read, that I can attach an extension to the cable - which is accessible in the loft by adding a junction box and additional cable? My question is what cable type do I use for the extended part. I have bought 1.5mm but on reading posts here I'm wondering if this is right. I've also bought a junction box with screws - but am now wondering if that doesn't count as maintenanceless - although it will be accessible in the loft? Help gratefully received :)

If the junction is in the loft, and you can access the loft (ie up a ladder, etc) then it is accessible.

I'm not sure how much additional cable you actually need, but you may find that you can win an inch or three by unclipping & rerouting the cable up in the loft.
 
1.5mm is fine I use some thing called a wago connector which are a push fit permanent connection you can buy them from screw fix or wholsalers. I always tape them as well even though you dont need to ive wired many a house using wagos, as I really dont like using junction box's don't think you can ever get a really nice connection with them the othet option is crimp connections again taped after they are crimped

6mm² is fine.

So are the J803s to which I linked which have a built-on enclosure.

Not necessary in an enclosure.

Except the ones which use the same method.

Solid conductors should not be crimped.
 
If he has already bought 1.5mm as stated then there is no problem using 1.5mm in fact I only ever use 1.5mm. Wagos will be alot easier to find as screwfix stock them. I missed where you are not allowed to crimp solid conductors , I never do but seen many a spark do it I wouldn't mind going through my regs if you can tell me where it sates you can't crimp.


Just checked on one of the other forums I use and the consensus is crimping is classed as a permanent connection. So if you could point out where the regs state I will let the other lads know.

The regulation, 526.3(iv), just says 'appropriate compression tool' which for solid cores crimps are not.

It has been discussed many times.

You will not find any manufacturers' examples of crimping solid cores.
 
What would be appropriate compression? Surely a join that can not be manually pulled apart would be classed as secure? Im always open to new info will ask my tutor fron my test and inspection course when I see him next for he's thoughts.

Why would there be one (for 1, 1.5 & 2.5mm²)?

Is that the criterion?

It's not new.

It will be interesting to hear whether he his correct or not. ;)
 
Nothing wrong with crimping solid conductors IMO. I do it all the time with no problems at all.
 
Well as you stated appropriate compression I thought you may know! The reason most people didn't crimp was due to poor cable copper and aluminium mixes from the 1960's from what I have been reading tonight many see crimping as acceptable as the near pure copper cable in use now will mould to the crimp obviously using a ratchet type crimping tool.
It seems there is many a spark who disagree with you options. But each to there own. I can't see why a properly crimped and insulated conducter wouldn't fulfill the requirements as a permanent connection

But as it it not supposed to be done there would not be one, would there?

It's not up to 'most people'.

That would seem to be a disadvantage with any spare room within the crimp (which there is).

It is neither my option nor a democracy.
Crimps were and are not intended for use on solid cores.

Ok.
 
Are you an inspector for niceic, napit, elecsa or another aproved governing body? just wondering as you seem to be 100% sure of your views where I have found many sparks who seem to disagree with you through many posts I have travelled through tonight and by sparks I mean not your 12day 17th edition course cowboys but by properly educated and time served trades men/ women
