→ cannotsleep: 耗比較多電XD 電表我不確定 但只知道上次裝冷氣 師傅08/14 15:32
→ cannotsleep: 有從電箱接220V的 應該說我們家總共有2處暗3處明的2208/14 15:33
→ cannotsleep: 0V都是可給冷氣用的 其中一處暗的220V現在沒有使用08/14 15:34
那就是有220V也有暗管啦
請工程人員拉在暗管裡面就可以了
5.5平方(4000w)或8平方(6000w)的多心線從總電箱處走暗管
到離屋後最近的那個220V插座在弄出來就好了
屋後出來這段再明線就好
不過一般儲熱式的不會吃到滿
我之前冷氣和4000w儲熱式用一條5.5平方線 20A開關是都沒跳過
現在冷氣和6000w儲熱式用一條8平方線 30A是也沒有跳過啦
