To crimp or not to crimp......

[Rob99]

I'm going to be wiring up a smart home panel in a couple of weeks using mainly 0.5mm tri-rated cable and wondered what the view is on using crimped ferrules on the ends of the cables to fit into the screw terminals of the various components.
Seems like a good way to avoid poor connections with stranded cable and the neatness appeals to my OCD side!

If a soldered end is under pressure such as in a screw terminal, the solder moves over time leaving the connection loose.

Indeed, cross purposes here. Soldered joints (other than dry joints!) are OK, although I do wish people would learn to make them properly, but tinned or solder-dipped ends of cables must not be put in screw terminals as mentioned above. I have seen this done so many times and they are invariably loose if not severed, or corroded from the flux. Only a few weeks ago I had to replace a 32A plug with a burned-out line terminal, where the ends had been tinned and all five cores were loose as anything due to cold flow.

OP- Bootlace!

I would just like to clarify that when i was using solder-dipped ends of cables they there for a 5 pin connector..10V

Priceless off topic diversion earlier..... Sadly its over 30 years since I could have any sort of "hair" style...!!!

With the exception of mains to the PSU's and a couple of relays it's all 24v

I always use ferrules on flexible conductors, is the past I would solder the strands together to form one solid conductor.
