standard 6.5.2.2 Green-and-yellow insulation shall not be used except for:
a) protective earth conductors;
b) PROTECTIVE BONDING conductors;
c) potential equalization conductors for safety purposes;
d) functional earth conductors. h) Protective conductors may be bare or insulated. Insulation shall be green-and-yellow,
except in the following cases:
1) for earthing braids, either green-and-yellow or colourless-transparent;
2) for internal protective conductors, and other conductors connected to the PROTECTIVE
CONDUCTOR TERMINAL in assemblies such as ribbon cables, busbars, flexible printed
wiring, etc., any colour may be used provided that no HAZARD is likely to arise from
non-identification of the protective conductor. xidua-10 发表于 2014-9-9 16:53 static/image/common/back.gif

我来翻译一下:
h) 保护导体可以是裸露或绝缘的。如果是绝缘的话,就需要是黄绿色,除以下情况:
1) 对于接地辫子(具体为何物,建议去阿里巴巴上搜索关键词earthing braids), 要么是黄绿色,要么无色透明。
2) 对于内部保护导体,如果有其它导体装配中连接到保护导体端子,例如ribbon calbles, busbars, flexible printed wiring等, 任何颜色都可以使用只要没有危险起因于无法辨识保护导体。
