better on stranded cable than solid core, always look a bit rough to my eyes. The ceramic ones had the huge advantage of staying connected while being run red hot, and the huge disadvantage of sometimes shattering leaving exposed bare ends pointing upwards. Not ideal in a loft for example.

In one of John Ward's videos, he put 90 amps through a 1.5mm cable containing choc block, wire nut, wago and crimp joins. The cable itself failed before any of the connectors did, which impressed me somewhat. Wire nuts still feel wrong to me, though.

In some ways better than the traditional connector block where conductors can pull out or be cut by the terminals screw.

I've come across a lot of the ceramic ones in old installations still doing their job, having had no maintenance for decades.

Occasionally I've come across them supplied with new light fittings, they do seem to work, I've tried them, I don't use them though because they don't seem very robust.

I haven't used them but when i come across the older ones the cables are always twisted first. Is that the correct way to install them ? Not something i would be keen on to be honest. I haven't used the 'modern' ones.

The correct was way to put them in flat then to wind up the screw-y nut

But many Americans tend to use the tips of their lineman pliers to twist up the cores then just pop the nut on it

I do see they have started using wago type connectors in the states now as part of code as one alternative to wiring nuts

Bought a mixture some time ago when Newey were promoting them. Used the weatherproof ones on 12v outdoor lighting. But the rest hardly ever used. Wago every time.

An olde chestnut. Porcelain Scruits are a simple means of insulating twisted ends of smaller, stranded or flexible cables, with no metal insert like the superior, plastic, thermosetting, American ones, and they should be taped on, .... not a time saving exercise, the use of Scruits is deprecated IMO, can they still be bought? .
