安规标准

不需要

应该要

C14 的inlet ,PE pin 如與output地端直接相連,這時算1類還是2類設備?這時PE pin與L,N之間要求基本絕緣還是加強絕緣?如果PE pin 與L,N接了y-cap,pe pin 與輸出地相連﹐這又如何?

只要有保护性接地,就算是I类产品,这时,接地与L/N之间只需要基本绝缘就行.

First, You shall make it clear that the creepage and clearance are depend on the working voltage, Of cource, you shall keep the rule before fuse (include the creepage of fuse).
