各位:SPT-3中地線的顏色是否有規(guī)定。比如是否只能是黃/綠,還是綠色也可以。謝謝!

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(biāo)準(zhǔn)的?

UL62中有對(duì)地線的顏色進(jìn)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%.
