Crimps in consumer unit?

[Engineer54]

Cheers Zap :smug: ive tried to dig out the solid core crimpers in the past to back my argument up but as you have found its a bugger to try get details and costing but this aside the very fact that they make a butt crimp designed for solid and a crimping tool to suit re-enforces my argument the standard £20-£30 ratchet crimpet in some sparkies tool kit is not suitable for solid nor are the R/Y/B crimps or why would they make ratchet and crimps designed for solids in the first place.

In order to take £190 out of those daft enough to put their hand in the pocket to pay it!!!

ive always extended cables by soldering and slipping a heat shrink sleeve over ..no need to get the soldering iron out for small cables .can be done with smoke lighter .think it gives a bombproof connection over a greater surface area as the solder bonds to every part of each wire .good for solid and stranded and when mixing the two types .

Crimps in cu. guys do you set any limits on numbers before a din rail. I was taught one or two as last resort but more and it's a no no. Would welcome your views.

Screwless connectors haven't been around long enough in domestic circuits to be able to say they are faultless.

Screwless connectors have however been around in commercial / industrial installations for a long time and they do fail.

was connecting legrand light switches on an ahu, they are terrible

Two issues I have with crimping cables are

1 - testing is a nightmare
2 - gotta cut the crimp off & discard if for any reason which is likely. Ceramic blocks I used for years till wagos came out. Hellermann are good too. I've realised con. Blocks have come down in price recently.

depends what type of crimp though.

for example in bms, you crimp all cables in ferrules then into temp sensors etc. to test you could put in connector block if you like (12/24v dc never hurt anyone)

My 2p worth
Properly done crimps are ok. even on solid cables.
Properly done Connectors are ok
Properly done JB's are ok

I think the key point here is the skill and care taken by the operator.
In reality how many 'well done' junction boxes have you had to locate and replace?
I know for a fact that virtually ALL of the ones that I have had to fault find have been bodged.

Been told years ago by by supervisor that soldering is a big no... in case of joint heating and de-soldering itself. i`m quite good with soldering, this put me off a bit, used crimps after that.

That type of solder your using there maybe OK for use on thin electronic wire, but i certainly wouldn't use it to solder mains voltage current carrying building cables.

The mind boggles at some of above lol crimp it, quick tug, and no strain on cables is as good as it gets to pulling in new cable that reaches
