Joining a cable to be buried in a wall

@pc1966 It works great. We no longer carry a mains one on the van. If I recall it was only about £99 as a bare unit off Amazon

I’ve used those a few times - keeps it nice and straight if you don’t have much slack

Bought one of these recently, with the deflector on it works surprisingly well: View: https://www.amazon.co.uk/Heat-Shrink-Tubing-Mini-Cordless/dp/B0064DGZPG/ref=sr_1_37?adgrpid=88288090060&dchild=1&gclid=EAIaIQobChMI8rLDkcrM6QIVNYBQBh0ykAG1EAAYASAAEgKh-vD_BwE&hvadid=408218351486&hvdev=c&hvlocphy=1007076&hvnetw=g&hvqmt=e&hvrand=7080332380222985000&hvtargid=kwd-359346914070&hydadcr=26613_1931084&keywords=butane+heat+shrink+gun&qid=1590326036&sr=8-37


I also bought a hydraulic crimper, bit awkward in tight spaces, but again extremely competent in squashing inline crimps: View: https://www.amazon.co.uk/HSEAMALL-Hydraulic-Crimping-Electric-Terminal/dp/B07VBMMDDT/ref=sr_1_1_sspa?crid=N7IDSW4HWEOI&dchild=1&keywords=hydraulic+crimping+tool&qid=1590326217&sprefix=Hydrolic+crim%2Caps%2C198&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFLRDkwVTBIQlRENjAmZW5jcnlwdGVkSWQ9QTAzMDU3NzYzU1ZPVDNSUVk5RENMJmVuY3J5cHRlZEFkSWQ9QTA4NjE0ODczMUhaOFBQR0YyRzRHJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==

What size cables are you intending to crimp Mike?

 

[Mike Johnson]

one of these with heat shrink over.

Surprising how these have now become acceptable, when I first posted about them, there where subject to all sorts of disparaging remarks, one even that the yellow lever should have been stripped green.

The inline crimps I have for 2.5mm are impossible to squash with a hand crimper: 2.5mm² Blue Butt Connectors - https://www.tlc-direct.co.uk/Products/CTBUTTslashB.html the above unit makes short work of it.

In a scenario of cable being drilled into for example, as a last resort the cable can't be replaced, joint can't be left above wall unit etc (Wago), I've used butt connectors & heat shrink, as you've suggested. I bought some of these, but not used them yet;

They'll be some arguing against using crimp connectors on solid cables, but I've seen that disputed on another forum.

PS Lets not have any book shelf jokes

Big Clive on YouTube tested these recently and as I recall was not too impressed with the results. The solder does not seem to flow into the connection too well. Think they are ok for low current applications, but that’s about all.

i've experimented with some of those solder connectors. the plastic melts before the solder. IMO..... RUBBISH.
