一切以标准说话。
. A$ s( C% E% ^7 m* g* n/ tcl 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.5 |3 E, [+ E+ i* b. ]5 J
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。( o# G/ c# b/ x' r8 c
并没有说一定要用特殊的螺钉。

所以我们要弄清“及格”和“优秀”的关系:器具的接地措施本来是可接受的,也就是说合乎标准了。你一定要厂家做到“优秀”,如果是建议厂家提高器具质量的角度来说是可理解的。但如果厂家做的器具合乎标准,你任是说人家不合格。这是不可取的。 |
