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.
