大連配電箱(也(ye)稱為(wei)配(pei)(pei)電(dian)(dian)(dian)板(ban)、配(pei)(pei)電(dian)(dian)(dian)板(ban)或配(pei)(pei)電(dian)(dian)(dian)板(ban))是(shi)電(dian)(dian)(dian)力(li)供應(ying)系統的(de)一(yi)(yi)(yi)個(ge)組成部分(fen)，它將電(dian)(dian)(dian)力(li)饋線分(fen)為(wei)輔助電(dian)(dian)(dian)路(lu)，同(tong)時在一(yi)(yi)(yi)個(ge)共同(tong)的(de)外殼中為(wei)每個(ge)電(dian)(dian)(dian)路(lu)提(ti)供保護(hu)熔斷(duan)器(qi)(qi)或斷(duan)路(lu)器(qi)(qi)。通常，一(yi)(yi)(yi)個(ge)主開關(guan)，以及在最近(jin)的(de)板(ban)，一(yi)(yi)(yi)個(ge)或多(duo)個(ge)電(dian)(dian)(dian)阻電(dian)(dian)(dian)流器(qi)(qi)件(RCD)或剩余(yu)電(dian)(dian)(dian)流斷(duan)路(lu)器(qi)(qi)與(yu)過流保護(hu)(RCBO)，也(ye)被納(na)入(ru)。

    大連(lian)配電(dian)箱母(mu)線(xian)(xian)(xian)將電(dian)流從(cong)輸(shu)入(ru)線(xian)(xian)(xian)(熱)導(dao)體(ti)輸(shu)送到斷路(lu)(lu)器(qi)，斷路(lu)(lu)器(qi)通(tong)過螺(luo)栓連(lian)接(jie)(jie)(jie)(jie)(使(shi)用螺(luo)紋螺(luo)釘)或(huo)插(cha)件連(lian)接(jie)(jie)(jie)(jie)(使(shi)用固(gu)(gu)(gu)定(ding)夾)固(gu)(gu)(gu)定(ding)在母(mu)線(xian)(xian)(xian)上。面(mian)板(ban)(ban)在商(shang)業和(he)工業應(ying)用中(zhong)(zhong)更為(wei)常(chang)見，并使(shi)用螺(luo)栓斷路(lu)(lu)器(qi)。住宅和(he)輕型商(shang)用板(ban)(ban)通(tong)常(chang)稱為(wei)負荷中(zhong)(zhong)心，并采(cai)用插(cha)入(ru)式斷路(lu)(lu)器(qi)。這些(xie)中(zhong)(zhong)性導(dao)體(ti)用螺(luo)桿端子固(gu)(gu)(gu)定(ding)在中(zhong)(zhong)性母(mu)線(xian)(xian)(xian)上。分支電(dian)路(lu)(lu)連(lian)接(jie)(jie)(jie)(jie)導(dao)線(xian)(xian)(xian)被固(gu)(gu)(gu)定(ding)在直接(jie)(jie)(jie)(jie)連(lian)接(jie)(jie)(jie)(jie)到面(mian)板(ban)(ban)外殼的接(jie)(jie)(jie)(jie)線(xian)(xian)(xian)盒上，接(jie)(jie)(jie)(jie)線(xian)(xian)(xian)盒本身(shen)接(jie)(jie)(jie)(jie)地。

    在(zai)大連(lian)配電(dian)(dian)箱(xiang)的(de)(de)維(wei)(wei)修過程中(zhong)，當配電(dian)(dian)箱(xiang)蓋被拆卸下來，電(dian)(dian)纜可見時(shi)，美國(guo)配電(dian)(dian)箱(xiang)通常(chang)會有一(yi)些帶電(dian)(dian)部(bu)件暴(bao)露(lu)在(zai)外。在(zai)加拿(na)大的(de)(de)服(fu)務進口板中(zhong)，主(zhu)開關或斷(duan)路(lu)器位(wei)于一(yi)個服(fu)務盒中(zhong)，即與面板其余部(bu)分分離(li)的(de)(de)外殼的(de)(de)一(yi)部(bu)分，這樣當主(zhu)開關或斷(duan)路(lu)器被關閉時(shi)，在(zai)維(wei)(wei)修分支電(dian)(dian)路(lu)時(shi)，就不(bu)會暴(bao)露(lu)帶電(dian)(dian)部(bu)件。
