标题: 保险丝温控在电路中的接法
我司做咖啡壶,对於保险丝和温控的接法,总有争议。在UL1082中似乎找不到明确的说法,保险丝是否一定要接在火线上,温控接在零线上。我能确定的是两者不能同时接在火线或零线上。

哪位大侠给个说法???

UL 1082:
SA11.3.4 If a grounding-type attachment plug is provided or the enclosure of the drip-type coffee maker
has metal parts that are likely to become grounded, such as a metal bottom with bumped-out metal feet,
the limiting-type device shall be located in the ungrounded supply conductor (if it can be identified) and
the temperature-regulating control shall be in the other conductor. If the ungrounded supply conductor
cannot be identified, the limiting-type device shall be located in one supply conductor and the
temperature-regulating control shall be located in the other supply conductor.

中文应该是:
如果滴漏式咖啡壶带接地型连接插头,或其外壳金属件可能变为接地(如金属底壳带活动金
属脚),则限温装置应位于非接地电源导线上(如果可以辨别的话),控温装置位于另一条导
线上。如果不能辨别非接地导线,则限温装置位于一条导线上,而控温装置位于另一条导线
上。

这样接,万一发热管内部对地短路,器具也不会因温控和/或热保险被旁路而出现危险的过热。
