crazy. 400A breaker . Removed one cable . You can not connect power back on. You will make fire on one cable.

要防止誤送電發生危險，正式的做法是掛牌子‘’工作中，勿送電‘’。
如果手邊剛好沒有牌子，簡易的做法是撕一段約12公分的電氣膠帶，中間沾貼在斷路器開關柄，上、下端貼在斷路器本體，行業內的人都看得懂。

Connect the cable it have few points need attention. 1. the cable indication for each phase 2. the earth point for switch board door, you need clean the paint some time point have resistance. 3. 1.5V DC cannot use on short circuit system, you need use Insulation tester to test the resistance between cable and leaking to earth.

师父你好，请问一下，一个电表接火线，一个电表接灵线，这样可以用吗??再请问是火线的付费，还是灵线的付费，备注两个电表使用权都是老爸的，两户是相连的，中间墙壁已打通，感恩。

[@taoyao4834]

电子电表内部计费和机械表一样也是通过火线电流计费的，只用电子电表的零线（而不是火线）电表不会计数。
是不是想跳接火线偷电啊？？？
供电部门就是通过测火线、零线电流是否一致来判断你是否偷电，小心哦！
