当你的小型断路器是三相开关，你要搞清楚入线是不是三相电路。如果确定是两相的，就应该零线接零线，地线接外壳，火线随便接一个就可以了。一般每个空调单 独分一路，厨房和卫生的插座分别单独分一路，其余的插座可以根据情况分一到两路，所有的照明也可以分为一到两路。预计要使用大功率电器的插座电路可可以使 用20安培的小型断路器，否则16安培的小型断路器就够了。

*的小型断路器，无论是从质量还是售后服务方面，都得到广大消费者的信赖和*认可，在这里要特别提醒广大消费者，特别是喜欢贪小便宜的消费者，在购买小型断路器时，一定要选择*的小型断路器，因为小型断路器质量的好坏直接与我们的人身安全息息相关，不容小视。MB1-63/2P小型断路器是值得你信任的产品。

下面就教大家小型断路器型号的选择，小型断路器的安装和接线方法，只有做好了这几步，才能发挥小型断路器的作用，更好的保护家人的安全，首先教大家小型断路器的电流选择：
MB1-63/2P小型断路器选择：
1、住户配电箱总开关一般可以选择双极32—63A小型小型断路器或隔离开关，MB1-63/C32/2P；
2、照明回路一般用10—16A小型小型断路器MB1-63/C16/1P；
3、插座回路一般选择16—20A的小型断路器MB1-63/C20/1P；
4、空调回路一般选择16—25A的小型断路器MB1-63/C25/1P；
5、采用双极或1P+N（相线+中性线）小型断路器，当线路出现短路或漏电故障时，应立即切断电源的相线和中性线，确保人身安全及用电设备的安全。以上小型断路器的选择仅供参考，每户家庭的实际用电器功率不一样，具体要按电工设计为准。
