一切以标准说话。; H0 E7 T. \5 k. M9 s
cl 26.1 However, earthing terminals may be accessible if a tool is required to make the connections and means are provided to clamp the wire independently from its connection.# j$ }4 n1 L q( s' z0 B$ P3 Y, b6 u Z
这里讲的是:接地螺钉可露在外面,但连接时需要有工具,并且需要有独*立的措施来夹紧螺钉。此紧固措施可以是弹簧或梅花介子。) a3 \0 {2 k! {* j7 w
并没有说一定要用特殊的螺钉。
