各位：SPT-3中地线的颜色是否有规定。比如是否只能是黄/绿，还是绿色也可以。谢谢！

我也想了解，地线有的是绿注黄,有的是黄注绿.到底是哪中颜色才是标准的?

UL62中有对地线的颜色进行规定如下：

4.1.9.1 (b) Grounding conductors shall be distinguished by the color green or a combination of the colors green and yellow. On a grounding conductor colored green, one or more yellow stripes that cover no less than 5% and more than 70% of the calculated circumference of the finished conductor insulation shall be permitted.

因此，地线颜色用绿色和黄色和绿色的混和色都是可以的，只不过黄色注条的比例不能少于５％或多于７０％．
