By the way a short look over the pond:

"Wagos" are the state of art in this millenium. Wire nuts and everything with any type of screws is regarded as antique because only the spring mechanism of a wago type connector is able to adapt to possible form changing of a copper wire. A German electrician rarely uses a screw driver to connect wires, he just "pushes in the wires", even on mcbs or neutral or ground bars.

"Scotchlocks" or alike have not been introduced into LV installations and are so far limited to cars.

On the other hand the Scotchlock like connecting principle is very much promoted and more and more used in industrial context, here called f.i. "QuickOn"(Phoenix Contact) or similar.
