Crimp or solder?

[DNS1]

What's the preferred method of joining T+E for an inaccessible joint? Ring final circuit...

Crimp and heat-shrink, or solder and heat-shrink?

Do I need to take any extra precautions if I'm connecting a new colour cable to an old colour cable (apart from the sticker on the CU)?

Whats wrong with a junction box?
or am I missing the point?

inaccessible mechanical joint!

if soldering, say, 1.5mm or 2.5mm, i wrap a bit of stripped alarm cable round the 2 ends, then solder and heat shrink. crimps are far quicker especially when i've left the iron or solder at home.

I am not a fan of solder, where there are temperature changes the joints invariably break down over time.

Crimp is always a good choice but call me lazy, I prefer lever or push fit connectors. When used with stranded conductors if there is any settlement in the cores the spring action keeps the pressure on. Not that they have been around for long enough to have passed the trials of time, but in theory ...

Of course to be MF the cables need to be clamped too, so best get a MF certified JB to cover yourself.

I'd solder, but I'm old fashioned

I crimp, then place the joint in a box and secure each cable to the box.

Must be lazy, always find heat shrinking to fiddly
