分支電路越多，電路可以為不同房間中的不同電氣設備（例如照明，插座，空調和廚房）提供的安全級別越高，因此，闡述如(ru)(ru)(ru)果(guo)一個(ge)(ge)電(dian)(dian)(dian)氣(qi)設(she)備(bei)發生故障，則(ze)其他房間中(zhong)的電(dian)(dian)(dian)氣(qi)設(she)備(bei)不會受(shou)到影響。如(ru)(ru)(ru)果(guo)分(fen)支線太少，則(ze)會導(dao)致功(gong)耗的不便和安全風險。例(li)如(ru)(ru)(ru)，如(ru)(ru)(ru)果(guo)分(fen)支線由于維(wei)護(hu)工作而(er)發生故障，則(ze)這會導(dao)致房屋中(zhong)其他位置的電(dian)(dian)(dian)源故障。如(ru)(ru)(ru)果(guo)回路太少，則(ze)電(dian)(dian)(dian)氣(qi)設(she)備(bei)會集中(zhong)在每(mei)個(ge)(ge)回路中(zhong)并相互干擾，從而(er)損(sun)壞更敏感(gan)的電(dian)(dian)(dian)子設(she)備(bei)，例(li)如(ru)(ru)(ru)家用計算機。

斷路器只能起到保護過載的作用，而沒有漏電保護的功能。如果需要，可以安裝漏電保護器。單極斷路器加漏電保護在中占用兩個電路(lu)。電氣保護(hu)只有(you)(you)在(zai)無(wu)電的情況下在(zai)人身(shen)前觸發時(shi)，才能(neng)真正(zheng)保護(hu)人身(shen)安(an)全。因(yin)此，必須(xu)與接(jie)地(di)(di)良好(hao)的接(jie)地(di)(di)線結(jie)合(he)使用。應定期檢查(cha)具有(you)(you)泄漏保護(hu)功(gong)能(neng)的斷路(lu)器，以(yi)確定泄漏保護(hu)功(gong)能(neng)是否有(you)(you)效。通常(chang)每(mei)個月單擊一次，如(ru)果(guo)可以(yi)立即斷開檢測按(an)鈕(niu)，則(ze)該按(an)鈕(niu)有(you)(you)效，否則(ze)需要更換。

配電柜廠家(jia)作為現代電(dian)(dian)(dian)(dian)(dian)(dian)力工程的主(zhu)要設(she)(she)備，配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)在家(jia)庭，公司和公共(gong)機(ji)構中(zhong)均具(ju)有關鍵(jian)功能。由于位(wei)置不(bu)(bu)同(tong)，所用配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)的類型(xing)也(ye)不(bu)(bu)同(tong)。當(dang)前的許多(duo)櫥柜(ju)(ju)產品不(bu)(bu)夠堅固，無(wu)法充分考慮勞動力需求。在這(zhe)種情況下，配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)箱的重新設(she)(she)計不(bu)(bu)會被(bei)延(yan)遲。配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)在運(yun)行期間會產生大(da)量熱量。因此(ci)，必(bi)須配(pei)備良(liang)好的熱導管來散熱。否則會危(wei)及機(ji)器和設(she)(she)備的正常運(yun)行。換句話(hua)說(shuo)，當(dang)配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)的內(nei)部(bu)相(xiang)對(dui)較大(da)時(shi)，可以在其中(zhong)安裝溫度控制繼電(dian)(dian)(dian)(dian)(dian)(dian)器和排氣風扇(shan)以促進(jin)配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)的熱量產生，并立即對(dui)其進(jin)行清(qing)潔(jie)。配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)的極限可以適度增(zeng)加，其目的是促進(jin)在不(bu)(bu)同(tong)部(bu)分之間增(zeng)加電(dian)(dian)(dian)(dian)(dian)(dian)氣安全距離，以防止內(nei)部(bu)組件相(xiang)互影(ying)響并產生負面影(ying)響。
