AS/NZS 3120中Current breaking test要求不甚明白：/ F$ M( J, s3 M0 a2 C
...2 ^- Z9 R4 u+ ^0 Z9 [
(a) A plug shall be inserted in the socket with no current flowing.' W. q3 E# P3 ]' {9 m9 D

(ii) shall be passed through a circuit including the plug and socket for 15 s.

以上是说插头插入插座时要求不通电流，插入后立即通电维持15S, 之后插头拔出插座，拔离插座的状态维持105S; 然后继续开始第二个循环吗？那有这样的插拔设备可以做到这个吗？一般我知道是直接机械插拔或者带电插拔，这个要求好像有点复杂，我也不明白标准这么要求是基于什么考虑？: M- F* D& k \; S' K' }

另外，以下这句话是不是表示，如果产品带接地，要求接地也通电流！Where an earthing contact and an earthing pin are included, the earthing terminal of the socket shall be connected to the neutral terminal during the test. j3 {1 {3 G+ {" L; h

期待高手解答，谢谢先La! |
