Oven cable

[JohnW2]

... if the mechanical joint is (I would think necessarily) based on twisting/knotting/plaiting/splicing etc. (if more than that, it would not really be a 'soldered joint'), then a sufficiently firm 'tug' would pull it apart - in practice, probably a tug no 'firmer' (actually probably 'less firm') than would be necessary to pull a conductor out of a properly-tightened screwed terminal (in the absence of adequate strain relief).

Personally I wouldn't recommend soldering wires to a DIYer, there's too many ways of incorrectly soldering.

I would have thought re-crimping with new crimps and a DECENT ratchet crimping tool, with the joint in an enclosure would be better.

I haven't seen Wagos for 6mm2 cable, so glad to hear they exist, as this would be good too.

I agree, but would go further and wouldn't recommend soldering to an electrician who wasn't well trained and experienced in doing it, and nor would I personally want crimping to be done by an electrician who was not well experienced in doing it, let alone a DIYer.

As I said, 773-173 Wagos will take up to 6mm² and, according to Wago, they are 'MF' if used in a Wagobox. If one believes that, this may well be the best option for DIYers and electricians inadequately experienced in soldering and/or crimping.

You can get maintenance free DIN-rail terminals which go up to 16mm².

Unfortunately nobody has offered (or will ever bother to offer, I strongly suspect) an enclosure marked MF for them, or declare BS 5733 compliance.

 

[JohnW2]

If there is no MF marking, nor any claim/declaration of BS5733 compliance, in what sense are they 'maintenance free"? Is this merely a reference to the fact that they do not used 'screwed' connections?

 

[ban-all-sheds]

The terminals themselves are said by the manufacturers to be maintenance free Whether there is an applicable standard for the terminals alone, IHNI, but they are a reputable company.

But as you know, there is more to having a BS-5733 compliant MF junction box than simply the terminals inside.

It's not the wago that's mf on its own, you need to put it in a suitable enclosure that needs a tool to open it and has the correct strain relief

Isn't that essentially what BAS has just said, in the last sentence of his preceding post?

Yes it seems so,
