Stranded wires often need to go into screw terminals:
But they’re not very secure connections, and you have to be careful that you don’t get stray strands of wire sticking out.
The answer to this extremely common problem that blights our civilisation?
So the next time you have to stick a stranded wire in a screw terminal:
… slip a ferrule on the end of the wire:
… squish it up with the nearest tool to hand:
Here, I’m using some crimpers, but you can use pliers, teeth, an anvil – whatever’s to hand. Go wild.
Now that’s a nicely terminated wire, if you know what I mean. You can snip the end off the ferrule with snips if it’s too long for your terminal.
Look at that. Isn’t that better? Strain relief, no danger of stray strands of wire causing short circuits that you spend an hour looking for; it looks neater… too many advantages to list.
To sum up: Ferrules. Oh yeah. Available wherever ferrules are sold.
