The term means electrically connected to a source of potential difference, or electrically charged so as to have a potential significantly different from that of the earth in the vicinity. The term "live" is sometimes used in place of the term "current-carrying," where the intent is clear, to avoid repetition of the longer term. 4 ?: F, }, _' d7 V 0 o; ]& O0 @& [* [) V7 g* u& TCurrent-carrying part. The term means a conducting part intended to be connected in an electric circuit to a source of voltage. Non-current-carrying parts are those not intended to be so connected. n% M" R: c) _

不同点：第一句说的是载流部件及SELV部件，第二句说的是带电部件。作者: Nezof 时间: 2012-8-7 09:24

那截流部件与带电部件有什么明显的区别？作者: Clears 时间: 2012-8-7 11:38
载流部件是电流可以通过的，诸如导线；带电部件是指物体带电，不一定要有电子的定向移动~~作者: gaolujie99 时间: 2012-8-7 13:05
不错，听君一席话胜读十年书！！
