Bootlace crimping tool recommendations

[Clive S]

One issue I see far too often, is everybody likes to default to blue insulated crimps (they're designed for 1.5 - 2.5mm² cable), when they should be using red ones (for 0.5 - 1.5mm² cable), which means they don't crimp correctly and you end up with bad connections.

For the cat5 flex I use the white But not sure if there is any stardard

I think some confusion between the ferrule colour coding and the spade terminal ("automotive") crimps.

Both of you are right, but you're talking cross-purposes :)
