Crimping 240v Twin and Earth - Safe??

[Engineer54]

Use a good ratchet crimper with good crimps on solid cores and you will have a sound permanent connection. The trick is to have a ratchet crimper that deforms the solid core within the crimp.

WAGOS are the way forward.

Everything you need to know about crimping... (almost)

Didn't notice anything about solid cores though, just had a quick scan through.

Note 2 on section 526.2 of BS7671 (aka 17th edition the wiring regs), which states: "Terminals without the marking R (only rigid conductor), F (only flexible conductor), S or Sol (only solid conductor) are suitable for the connection of all types of conductors

Welcome to th forum sizzler... to correct you; you need to read your regs quote again.its in reference to soldered connection, im confused to where your post is leading as the thread was discussing straight crimping.

Frankenstein along with this thread still lives. 2008 the thread started, why couldn’t it be left to rot?

So have people's views changed at all on crimping?

gas powered soldering iron, some solder and heatshrink, job done. maintenance free forever.

Just keep firing up that re-animator and jump-starting this practically medieval thread....

Depending on the situation I'd use through crimps and heat-shrink as a 'get out of jail free card' as an absolute last resort, in preference to connector block.
It's not something I'd say is 'fine' though, just 'barely acceptable', and not in every situation.

Someone let @TonyMK11 know that the thread IS ALIVE!!!!
Saying that - when I started training and joined the forum, this was the very first question I had in my head and reading this gave me answers.

Not really. Crimps that are unsuitable for solid conductors are still unsuitable for solid conductors. Unbranded crimps that aren't made to any particular specification still aren't made to any particular specification. And I still don't like through joints inside containment. More than once I've seen a large chunk of an installation put out of service after an overheated (i.e. bad) connection in one circuit burnt through the insulation of all the others sharing the containment. If you are going to splice a circuit in trunking the work has to be absolutely beyond reproach and I don't think wholesalers' own-brand bargain packs of crimps fitted with an unmatched, uncalibrated tool really cut the mustard.

ideal butt splice push-in connector for me.

Push connectors (Ideal/wago) inside a suitable enclosure.

Me too. I didn't like or trust them at first but they get my vote now. I also use their 4 port 32A push fits.

 

[Leesparkykent]

+1 for the ideal butt splice push in connector.

 

[Guitarist]

What many people don't realise is that push connectors aren't a new fangled invention... The Germans have been using them since the 60's. Get fed up of hearing that only the good old choccy blocks can be trusted.
