请教:230V户外灯串的插头线径要多大,有何规定? ' M; f. s- J, k 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?% q2 f0 ]. F( `0 b4 U) O+ R% z2 ^0 B
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 P# J- n, _6 ^- ?8 |! P" D 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?作者: af204 时间: 2007-12-18 09:50
可以看60598-2-20：A2：2002 部分，有规定的作者: legang 时间: 2007-12-18 10:34
