There is an AC ammeter with two pins. One is 5A and one is 0. Where should the live wire be placed? The 5A or 0? What does 0 mean?

No need to identify the two pins, because it is an AC ammeter, just connected it in series between one point of the supply and one point of the load.

5A的應該接電源正極，或正極通過負載回流負電一端，要記住，電流錶是串連電路的，電路斷線就沒有電流
