EN60204 and twin ferrules

Dave in the shed

Hi All,

EN60204 states: "The connection of two or more conductors to one terminal is permitted only in those cases where the terminal is designed for that purpose." Does anybody know whether this prohibits the use of standard twin ferrules (where two wires are crimped into a single ferrule) or whether the assembly of two wires and a ferrule is somehow considered to be a single conductor in the eyes of the standard?

Twin ferrules seem to be commonly used in machine building, often with claims of compliance with 60204. I was expecting to find some easily accessible guidance/knowledge/definitions regarding this situation but my web trawl hasn't found much.

Any wisdom will be gratefully received. Thanks.

    Thank you GTB - valued input once again.

    I'm in agreement with everything that you've said - all pointing towards there being nothing forbidden in the use of the humble twin ferrule.

    I'm unfamiliar with the terminology of "honeycomb linking assembly" but I'm guessing that you might be referring to something like this:

    If that is indeed what you're referring to then it's an excellent relevant example that I hadn't thought of. The MCB commoning bar shares a lot of commonality with the concept of the twin ferrule in terms of the 60204 one conductor/two conductor quandary - marvellous stuff.

    Thanks again.

    Dave in the Shed,

    No problems sharing my thoughts, below is a image of a terminal linking assemby that I and others would call a honecombe type this being more for terminals than MCB's, but you are spot on principal is the same.

    Cheers GTB
