I am watching a lot of videos of handy shop tricks and most seem to be coming from Europe or Oz/NZ based on the wire colors and equipment. They consistently show mains voltage wires twisted together and taped or shrink wrapped with no splicing device. Is that legal there?
When I watch, I always assume they will solder them or something but nope, just twisted and taped. Some of the splicing ideas are cool, particularly with the stranded wire but I would want to solder it.

In my overseas experience, connections were always to screws. In place of wire nuts free-floating terminal strips (“Choc blocks”) with shielied screws were used. (1980’s)
