沒錯, 你要注意先滿足以下條款: + G# V' P3 I2 d& ?

但是标准中说的是接线端子,如果我把接线端子固定在接线盒里面,拧开接线盒的螺钉或者螺母的话,接线端子本身没有松动,因为它已经固定住在接线盒里面了。 p, K( |1 y% ^$ R1 G& `

但是标准里面这段我看不明白:
. [" M& R. }1 b5 J5 {. CCovering with sealing compound or resin is sufficient to prevent a terminal from working loose,

是不是类似于接线盒这样的防止接线端子松动的装置不应该受力??大家是怎么理解这话的 |
