& \! n. e; b) @) \% w     1.有人说现在到欧盟的230V户外灯串的插头线径必须1平方以上,是有这样的规定吗?
      2.但也有人说是:到欧盟的230V户外灯串的插头线径求0.75平方以上就可以了,是这样的吗?
      3.但我公司今年换证的GS证书上说是0.75平方以上的插头线是,那就是可以用0.75平方以上的电线了,是这样的吗?

可以看60598-2-20：A2：2002　部分，有规定的

英文看不明白,最好能发个有中文的吗?

要看灯串的具体情况而定。

For sealed chains, the internal conductors may have a cross-sectional area of 0,4 mm2 or less
provided the current-carrying capacity and the mechanical properties are adequate. In addition,
conductors without insulation are accepted provided adequate precautions have been taken to
