标题: UL22.7条款的说明
22.7 A switch or other device controlling one or more elements of an appliance intended for permanent connection to the power supply shall be of such construction that opening the switch will disconnect all of the ungrounded conductors of the supply circuit, unless there will be no live parts exposed to unintentional contact when the switch is open or unless the fact that such parts are live parts is apparent.

个人理解为:带有连接电热管的开关,开关线路不能断开电源电线路;
5 r, y! G0 ]; C+ G8 w  如果我在开关后面还有一个计时器来控制总的线路,这样连接行不?

22.7 开关或者其他控制装置控制永久性连接电源器具的一个或者多个元件,开关应当完全断开所有非接地电路连接,除非开关断开时,非故意接触到情况下,没有带电部件暴露,或者这些部件非常明显是带电部件。% v6 }; q/ p$ x1 b, A4 ?
1 E; I8 ~9 g6 ?: G& ~1 Z
简单点说就是永久性连接器具要求全极断开或者非全极断开应该没有带电部件。7 _4 Y- {; p0 M( C. `2 \

F哥,这句是不是应该翻译为除非那些可能被非有意触及的零部件是明显带电的
, R. M) p/ E/ ?2 Z1 S意思就是如果有带电的可能被非有意触及的零部件那应该很明显的识别出来,例如有警告标识?
