選擇正確的標稱容量和正確的標稱電流很重要。重要的是要注意，斷路器的額定值取決于將來使用的電氣設備的數量和電纜的尺寸。它不能太大或太小。如果將斷路器的額定電流選擇得太小，則容易頻繁跳閘并導致不必要的電源故障。如果選擇太大，將無法達到預期的保護效果。用(yong)于(yu)家庭裝修的空(kong)氣(qi)開(kai)(kai)關(guan)(guan)的常見型號和規格為C10，C15，C20，C25，C32等。通常，使(shi)用(yong)C32可(ke)以輕松地安裝6000W快(kuai)速熱熱水(shui)器(qi)(qi)和7000W電(dian)熱水(shui)器(qi)(qi)。 8500W以使(shi)用(yong)更大的空(kong)氣(qi)開(kai)(kai)關(guan)(guan)，并(bing)使(shi)用(yong)單獨的空(kong)氣(qi)開(kai)(kai)關(guan)(guan)。電(dian)路使(shi)舊(jiu)房屋通常不能使(shi)用(yong)高(gao)性能，快(kuai)速加(jia)熱的熱水(shui)器(qi)(qi)。

空調電路通常有兩個以上的電路，帶有4條方形導線，每個電路使用一個20A斷路器，沒有漏電保護。空調回路不必使用具有漏電保護功能的斷路器，而只需使用普通的單相斷路器。如果空調回路使用漏電保護器MCB，則少量的泄漏會導致空調回路的漏電保護器MCB頻繁跳閘。我已經看到，許多帶有防泄漏MCB的建筑物的中的(de)空(kong)(kong)調(diao)回路(lu)(lu)不(bu)可用，但是(shi)一些(xie)機柜(ju)空(kong)(kong)調(diao)回路(lu)(lu)配備了防(fang)泄(xie)漏MCB。空(kong)(kong)調(diao)回路(lu)(lu)應(ying)使(shi)用特殊的(de)16A插座，配電箱生產廠(chang)家安裝(zhuang)位置應(ying)位于空(kong)(kong)調(diao)下方或旁邊，以方便切換。

通常(chang)，新大(da)樓的(de)(de)配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱(xiang)(xiang)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路交叉點(dian)的(de)(de)開發(fa)人員(yuan)已經完(wan)成，但舊房子的(de)(de)原始(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源線相對(dui)較(jiao)細，原始(shi)插座的(de)(de)接地(di)線可能不符合電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力安全(quan)標準。現在(zai)大(da)多(duo)數(shu)的(de)(de)老建筑都在(zai)北(bei)京，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路已經擴大(da)，但只在(zai)前(qian)門。配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱(xiang)(xiang)生產(chan)廠家(jia)必須(xu)更換內部所(suo)有不合格的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路，并重新組裝(zhuang)開關盒。配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱(xiang)(xiang)有兩種類(lei)型(xing)：裸露安裝(zhuang)和(he)暗裝(zhuang)。裸露的(de)(de)設(she)備直(zhi)接釘(ding)在(zai)墻上，進(jin)出線也(ye)都是裸露的(de)(de)管道。隱藏的(de)(de)裝(zhuang)置在(zai)墻上，進(jin)線也(ye)被(bei)掩(yan)埋。配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱(xiang)(xiang)通常(chang)安裝(zhuang)在(zai)容易觸及的(de)(de)地(di)方(fang)。它可以隨時(shi)打開和(he)關閉以檢查(cha)和(he)維(wei)修電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路。但是，位置不應(ying)太明顯。您可以創(chuang)建裝(zhuang)飾蓋。互聯網上有各種類(lei)型(xing)的(de)(de)配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱(xiang)(xiang)裝(zhuang)飾圖片。配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱(xiang)(xiang)的(de)(de)尺(chi)寸由分支(zhi)交換機(ji)的(de)(de)數(shu)量決定。
