给一个设备配电源线,懒得计算的朋友,最简单可靠的办法就是看该设备出厂原装电源线的大小。然后最低选和原厂一样大的电源线,稳妥起见也可以选比原装电源线大一个规格的电线。

如果你想要装即热式热水器,还需要考虑一下主线是否能负担的起。现在很多房子的入户线都采用6-10平方的铜线,计算功率一般在10KW以内。在设计的时候根本没考虑这种“异类反常规”用电设备,贸然使用容易出现跳闸或者烧线的情况。

  • 万用表测量交流、直流电压,区分火线和零线,就是这么简单
  • 判断空开和漏保的好坏,电笔比万用表还好用,可算长见识了
  • 空开和漏保:A、B、C、D系列有什么区别?跟着老电工长长见识
  • 电线接头一受潮就漏电,电工胶布这样缠,就算泡水里也不会漏电
  • 插座一用电就跳闸,原来是零线共用惹的祸,老电工轻松解决了
