Using Connection Strip with Ferrules

Former Community Member over 5 years ago

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.

Thanks for your reply. I was concerned about the insulation and thanks for your opinion.

Besides, I know it is a good practice to encase IEC 60288 Class 5 and class 6 finely stranded flexible conductors with ferrules, I want to know if there is a mandatory regulation in BS standard other than BS EN 60079 (explosive atmosphere) that mandates the use of ferrules for IEC 60288 Class 2(Stranded), Class 5 and class 6(Finely Stranded) conductors.(Inside Panel Boards and in Junction boxes)
