我就是修电梯的，工地上经常零时电！好多工地电工比较糊，只要能用都不会去搞电的！数字万用表一般用二极管档测是否接地，除非接地电阻比较大 才用电阻档去测

看到這篇，最近正好裝冷氣，我們是外機接好才接開關箱，就是怕誤開，習慣有差 即便開關箱算水電的我都沒讓他提早接，我們窮，怕炸機板賠錢。😎

使用中的高壓電線剝了線隨意丟地上, 如果再下雨不是會作死嗎

对于数字万用表，尝试选择 2M量程检查漏电。👌 200M范围太敏感，无法检查漏电。。

自动量程表试一下。在速卖通Aliexpress网站买一个才100块RMB块连邮带税，加上10天等待。还有电容档，例如AP3D。

數位錶歐姆檔位太大了

Design circuit, multi step section protection is important. Used 500mA Rccb for 400A building design. Is wrong. Very difficult, need more time when tracy fault. Should used 40A EF, and Aic Cond use 500mA Rccb.

空调没送电最多检查线路到冷气接线盒这一段有没有漏电 因为空调有交流接触器 空调要送电测才能检测压缩泵有没有烧

看不到小黃車

有施工還找人查問題怎麼找啊

[@hobodog0]

量程问题

[@ssb5171]

什麼亂七八糟空調施工方法 先併線再延長施作

[@DDnight546]

線頭直接丟地上也太他媽不負責任了吧

電梯都修😂
