我也想了解，地線有的是綠注黃,有的是黃注綠.到底是哪中顏色才是標準的?

UL62中有對地線的顏色進行規(guī)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，地線顏色用綠色和黃色和綠色的混和色都是可以的，只不過黃色注條的比例不能少于５％或多于７０％．

學習了
