Crimping 240v Twin and Earth - Safe??

[ngunge]

Hello, I would like to know what the regs say on crimping 240v 1.5mm twin and earth (single core) using red straight through crimps...

Is it legal/safe/can it be done and pass inspection etc etc?

What can I do/use instead of using a chockblock (connnector block) to join 1.5mm twin and earth together in trunking?

Crimping, soldering, heatshrinking?

Thanks

Maybe I did jump to conclusions.

If I was after crimps I'd just grab the Screwfix/Toolstation catalogue and whip down to the local branch, but to be fair to Nicholas Owen, his profile says he's in Wales, where those places are apparently very few and far between!

As someone else has said, CPC is would be the best bet. Seeing as they charge a bit for delivery, a bulk order would probably be a good idea, maybe one of the trade packs with a few hundred of each type/size.

Its Saturday and my nearest Screwfix and Toolstation is over 50 miles away!

I had a look, but when you search for crimps you have a few different ones come up and none of them have pictures.

All I asked is where he got his from as all I had up on Google was Maplin. Of course I looked on my usual sites including CPC but not knowing what to search for you get some wired results.

Anyway Im doing an order in the next few days with CPC so I will get them then

Try google 'cable ferrules' instead of crimps, you should get more accurate results.

We pay the equivalent of about 3 quid for a pack of 100 x 2.5mm uninsulated.

Or you could get some Wago's ..... quick, easy............ if your going to crimp make sure you use a good tool and good quality crimp

Do you mean these sjhall?

Only problem I see with these is that they are not maintenance free are they and therefore they will need to be inspected wont they?
Correct me if I am wrong please

I cant quote this as I haven't looked, (sure it is in there) however I believe that 7671 says that if a connection has a fixing (i.e. choc block) it must be accessible so that rules that out.. Next is a crimp connection (suitably protected) would do this job... Just make sure that the crimps are copper (same as conductor) and you test the installation after.

Hi Mate, yes they are the ones, I thought you wanted to extend inside the Fuse board ..... I think Wago's are maintenance free in the right enclosure from what iv read on here ...... need to double check though.

These heat shrink butt splices are they suitable for 6mm shower cable?

I have looked at a few of them and they come up with 16A - fine for 2.5 T&E and 1.5 T&E

Of course you would get the correct size - i.e. 6mm one

To be honest, i've never noticed a current rating attached to crimp terminals. I would have thought that the rating would reflect the largest size of the cable, they have been manufactured to accommodate.

The heatshrink is 90c as, as far as i know, all heatshrink products are based on XLPE plastics, so far more suitable than standard 70c insulated crimp terminations. Also available, is low temp solder heatshrink butt connectors. ...There is also a combined crimp and solder variety of heatshrink terminations, that can combine the properties of both crimping and soldered jointing.

the yellow 6mm crimps are rated around 40A. if buying from cpc, make your order up to £50 ( ex. VAT) and it's then free delivery.

I just use WAGOs.

Thanks

I have made an order already costing over £100 with them so stuck them on the back of it - 4 different sizes and the crimping tool - they are not cheap!

Interesting reading through this so many against crimps? I crimp cables and have never really thought it was a bad practice or frowned upon? I usually crimp cables and then use self amalgamating tape to secure and protect the joint?
Is this deemed bad practice?

 

[GLENNSPARK]

nowt wrong with crimps...if done correctly.......

 

[GLENNSPARK]

you use whatever jointing method is both compliant AND appropriate...for the scenareo.....
