那不就是8.2.3了吗?启动器可以的注意:I类就不可以触及基本绝缘了
请问老兄以下两个问题:
1. For class I luminaire, the basic insulation wire may be touched in normal use,meanwhile , the test finger may touch the earthed metal part. Is the construction acceptable?
2. When changing one bulb in wall lamp, the live parts behind lamp holder may be touch, is it OK?
(Please note the live part located on lampholder, and used to connect internal wires)

1,接地的目的是什麽?就是不用the test finger也可以随时接触接地accessible part啦,那肯定没有问题,如果这样都不行那1类灯全部fail了
2,对于更换光源,我觉得螺口卡口是可以接触live part
不过这问题好像是我提的吧 兄弟
呵呵...
