I am familiar with this system. Perhaps it is used in Canada- I'm told Canada doesn't allow the use of wire nuts.
These terminal strips differ from what we see in the US by coming in long "blocks"; you break off and use as many ports as you need. There are (noninsulated) "combs" that you use to jumper adjacent ports together.
Usually, the terminal strips are free-floating; that is, not anchored to the enclosure.
Some of the appliances from Europe will come with these. I have no problem in using them.
