  3. Cross-section:<\/strong> the declared mm\u00b2 or American Wire Gauge (AWG) size. When the terminal provides an AWG range, use that range directly; a rounded unit conversion does not establish acceptance.<\/li>\n

    The scope of IEC 60947-7-1:2025<\/a> covers industrial support-mounted terminal blocks for round copper conductors, including conductors with special preparation. That broad scope does not tell you the capacity of an individual terminal. The model’s declared connection data must complete the conductor record.<\/p>\n

    If you are still identifying the required terminal form or circuit configuration, start with what a terminal block is<\/a>. Once the conductor is known, compare the available connection methods. The screw-versus-spring terminal-block guide<\/a> covers their wiring and maintenance tradeoffs; here, the task is to establish which exact part accepts your connection.<\/p>\n\n\n\n\n\n\n\n\n\n\n

    A rated or nominal cross-section is not a full list of accepted conductors. Read the minimum and maximum values for the actual wire construction and preparation. The same model can have different rigid, flexible and ferruled capacities. A range for one preparation cannot fill a missing row for another.<\/p>\n

    YOCL\u2019s SJ cage-spring terminal-block table<\/a> makes this distinction visible. It lists separate rigid and flexible wire ranges:<\/p>\n\n\n\n\n\n\n

The input is a hypothetical 4 mm\u00b2 flexible conductor. SJ-2.5 fails that check even though its rigid range reaches 4 mm\u00b2. SJ-4 passes the range filter; its end preparation, conductor count, electrical conditions and mounting still need confirmation.<\/p>\n

    The SJ table does not separately declare bare-versus-ferruled or twin-ferrule ranges. If the 4 mm\u00b2 wire will carry a ferrule, the flexible range alone does not approve that prepared end. Request the applicable capacity and preparation instructions.<\/p>\n

    Read other series just as carefully. In the YOCL PT push-in table<\/a>, the PT2.5 entry identifies 2.5 mm\u00b2 as its rated cross-section. That single value is not a complete minimum-to-maximum connecting range. Do not copy SJ ranges into PT2.5, or borrow another manufacturer’s data because a model name looks similar.<\/p>\n

    Check the prepared end as well as the copper size<\/h2>\n

    A ferrule changes the outer envelope presented to the clamp. Its sleeve, collar and finished crimp must fit the terminal’s permitted preparation. The receiving terminal must accept that arrangement; selecting a ferrule with the correct nominal wire size settles only one part of the connection.<\/p>\n

    Conceptual conductor-preparation study. Each end needs its own documented connection-capacity check; the illustration does not approve a wire-to-terminal combination.<\/figcaption><\/figure>\n
