Using Connection Strip with Ferrules

When connecting flexible wires using connection strip with screws  it is recommended that one uses cord end sleeves or ferrules. What I realized if I connect two ferrules (1 In and 1 Out) the Insulation Jacket of ferules will not sufficiently enter the hole . and installation will end up as the attached figure. I am wondering if such connection is acceptable.

Note: in most cases I have 2x2.5mm2  Flex Wires In using Twin Ferrule and 1x2.5mm2 Flex wires out using single ferrule and I am using 10mm2 Connection strip

Another question is it acceptable to cut a little bit from the crimped ferrules so that they will enter sufficiently.

    Personally I always use "bootlace" ferrules - i.e. the ones without any kind of insulating sleeve. The wires then terminate just like solid core wires.


    When you say "the Insulation Jacket of ferules will not sufficiently enter the hole" are you suggesting that there's then insufficient conductor under the screw to make a proper connection? Is so then I would say that was indeed a problem. If it's just a matter of a gap in the insulation, then I don't see a problem - the system is likely only needed to be IP2X (finger proof) and probably not even that if it's not accessible without a tool.
