仔细翻查了一下UL498,
178.5.2 An attachment plug that is intended to accommodate fuses that can be removed after the attachment plug has been inserted in a receptacle shall be marked “Disconnect power before replacing fuses” or an equivalent wording.
如果power cord没拔出,Fuse则不能被取出的话,应该可以不用标准这句警告语,希望楼下有人帮忙斧正。谢谢!
