Reply to comment by tired_and_fed_up in Why should wires not be twisted before putting in wire nut? by dhekurbaba

Wire nuts are virtually unknown in Europe, we mainly used the screw terminals historically but last few decades Wagos are taking over, especially in the DIY segment in Northern Europe.

Wago 221s for life.

Wire nuts are very common - on stranded wires - in Northern Europe (Sweden). Every house I’ve seen has them in the junction boxes. That said, screw terminals (‘sugar cubes’) have a place as well. But they are not better than wire nuts properly applied.

UK - never seen one.

Never saw one in Italy, either.

I can't even imagine why you'd want to use them, to be honest. They're fiddly as hell.

And as others have echoed: Wago nowadays. Every electrician I know has gone for just having a box of Wagos and the last two I asked (who were working on large installs for workplaces) didn't even carry screw terminal blocks with them any more.

Maybe because properly applied, few connections are as electrically solid as when using wire nuts. But they sure are used more here in the US - where electrical standards are about a century behind Northern Europe.

"Wire nuts are not used in the UK because the old ceramic ones were banned many years ago for good reason"

I don't think they're any more solid, and there's a lot of talk that they weaken the connections over time / repeated use.

I've lived in houses (and worked in workplaces) with 40's and 50's wiring (and a couple of workplaces with literal 100-year-old wiring still in place, but unused) and things never came loose, just the opposite.
