對于配電箱廠家批發中的低壓配電柜來說，為了保證順利使用，是要進行調試的，主要包括機械試驗和電氣調試兩個方面。注意配電箱、開關箱，都是應該采用的鋼板或阻燃絕緣材料制作，而且裝設的電源開關，應具有短路保護、過載保護功能，其額定值和動作整定值應與其負荷相適應。在大連配電箱總配(pei)電箱、開關(guan)箱中，還必須裝設漏電保護器(qi)。

    在低壓供電(dian)系統應設(she)置大(da)連配(pei)(pei)電(dian)箱(xiang)總配(pei)(pei)電(dian)箱(xiang)、分配(pei)(pei)電(dian)箱(xiang)和開(kai)關箱(xiang)，實行(xing)三級配(pei)(pei)電(dian)，其中總配(pei)(pei)電(dian)箱(xiang)應該靠近電(dian)源，而分配(pei)(pei)電(dian)箱(xiang)應裝(zhuang)設(she)在用電(dian)設(she)備相對集中的地區。施工用電(dian)動(dong)(dong)力配(pei)(pei)電(dian)與(yu)照(zhao)明(ming)配(pei)(pei)電(dian)宜分箱(xiang)設(she)置，當合置在同一箱(xiang)內時，動(dong)(dong)力與(yu)照(zhao)明(ming)配(pei)(pei)電(dian)應分路設(she)置。

    大連配電(dian)(dian)(dian)(dian)(dian)箱(xiang)電(dian)(dian)(dian)(dian)(dian)氣操作(zuo)實(shi)驗是(shi)在(zai)安裝和接(jie)線都正確的(de)前提(ti)下，按電(dian)(dian)(dian)(dian)(dian)氣原理圖進行模擬動(dong)(dong)作(zuo)驗，即(ji)通電(dian)(dian)(dian)(dian)(dian)試(shi)(shi)驗；聯鎖功能試(shi)(shi)驗是(shi)通電(dian)(dian)(dian)(dian)(dian)檢查操作(zuo)機構與門(men)的(de)聯鎖，抽屜與門(men)的(de)聯鎖。在(zai)合閘(zha)通電(dian)(dian)(dian)(dian)(dian)情況下，門(men)是(shi)打不(bu)開(kai)(kai)的(de)，只有分閘(zha)以后，才(cai)可以開(kai)(kai)門(men)總配電(dian)(dian)(dian)(dian)(dian)箱(xiang)內的(de)漏電(dian)(dian)(dian)(dian)(dian)保護器額(e)(e)(e)定(ding)漏電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)作(zuo)電(dian)(dian)(dian)(dian)(dian)流應為50-100mA，額(e)(e)(e)定(ding)漏電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)作(zuo)時間(jian)(jian)應大于(yu)0.1s；而開(kai)(kai)關箱(xiang)內的(de)漏電(dian)(dian)(dian)(dian)(dian)保護器額(e)(e)(e)定(ding)漏電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)作(zuo)電(dian)(dian)(dian)(dian)(dian)流不(bu)得(de)大于(yu)30mA，額(e)(e)(e)定(ding)漏電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)作(zuo)時間(jian)(jian)應小于(yu)0.1s。
