那不就是8.2.3了嗎?啟動(dòng)器可以的注意:I類就不可以觸及基本絕緣了
請(qǐng)問老兄以下兩個(gè)問題:
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,接地的目的是什麼?就是不用the test finger也可以隨時(shí)接觸接地accessible part啦,那肯定沒有問題,如果這樣都不行那1類燈全部fail了
2,對(duì)于更換光源,我覺得螺口卡口是可以接觸live part
不過這問題好像是我提的吧 兄弟
呵呵...
