Dear Group,

What is the percentage of color over a surface area for the insulated
green/yellow earthing conductor. Is it better to have more yellow than green
or more green than yellow. I know North Americans prefer more green than
yellow and Europeans like more yellow than green. Any historical reason? I
hope it has nothing to do with the Boston Tea Party! Can the group we come
up with some compromise?

BTW IEC 60 204 standard for electrical equipment for machinery states "the
bicolour combination GREEN-AND-YELOW shall be such that on any 15mm length
one of the colours covers at least 30% and not more than 70% of the surface
of the conductor, tje other colour covering the remainder of the surface".
