电焊机接地线安装规范
作者:三十万装修笔记
前一段时间农村老家旧房子拆了重建,我们都知道农村用电是没有地线的,如果有值有新建房子,记得一定要在打地基的时候布置地线桩会很方便,那种后期需要地线在钢筋上接的方法不可取。盖房子我也是没想到,后期制作了地线,分享一点点心得,有可能不太准确,希望大家指点。
1、做水电前需要和电工师傅说好,插座布置三根线,可以根据火零地使用红、蓝、双色电线来区分,电线家里早期装修有预留,所以零线用的黄色,火线红色,地线双色线
2、材料:50热镀锌角钢 2.5m 三根

3、50热镀锌扁铁 5米2根 用来连接
我没有电焊机只用了6平方的铜线来连接,记得在扁钢20-30公分处开个孔洞,使用了8个镀锌螺丝压了铜鼻子。
三根50热镀锌角钢 间隔5米 分别打下土壤里,干燥的地区记得雨后打容易一点,每个地方土质不一样,2.5米的确有很大的难度,除非有机器操作,用锤子可不简单,过程太麻烦没拍,我用锤子敲了三根每个露出大概10-40公分,后来我用切割机切掉了

为了安全起见我把地线安装在离房子较远的位置,那里老妈养鸡的院子里,潮湿,接地电阻更低。

使用接地电阻测试仪测试每根扁钢的接地电阻,摇表的更准确,这款电子误差也不大。
家用接地线接地电阻应小于4欧姆
三根连在一起测的接地电阻3.53欧姆,土质还不错,如果接地电阻大于4欧姆建议使用盐水浇灌。

地线做好后,主线接入配电箱,自己重新整理了一下配电箱
家里剩余空开,漏保 全部整上,样子不好看但是可以省一批费用。

总结一下,有需求做地线的,可以参考一下,我不是专业的,请各位多多指点。
配电箱是左火右零,还是左零右火?
