暗裝配電箱，配電箱嵌入墻內安裝，JP柜在砌墻時預留孔洞應比配電箱的長和寬各大20mm左右，JP柜價格預留的深度(du)為配(pei)電箱(xiang)厚度(du)加(jia)上洞內壁(bi)抹灰的厚度(du)。在圬(wu)埋配(pei)電箱(xiang)時，箱(xiang)體與墻(qiang)之間(jian)填以混凝土(tu)即(ji)可把箱(xiang)體固定住。

必須選(xuan)用符合GB 6829《剩余(yu)電(dian)(dian)(dian)流動作(zuo)保(bao)護(hu)器的(de)(de)一(yi)般要(yao)求》標準、并經中國電(dian)(dian)(dian)工產品(pin)(pin)認證委員會(hui)認證合格的(de)(de)產品(pin)(pin)。可選(xuan)用類(lei)似(si)LJM（J）系列節電(dian)(dian)(dian)型、且是(shi)低靈敏(min)度的(de)(de)延時型保(bao)護(hu)器。保(bao)護(hu)器裝(zhuang)置的(de)(de)方式要(yao)符合國家GB13955-2005《剩余(yu)電(dian)(dian)(dian)流動作(zuo)保(bao)護(hu)裝(zhuang)置的(de)(de)安裝(zhuang)和運行(xing)》標準。漏電(dian)(dian)(dian)保(bao)護(hu)器的(de)(de)分斷時間，當(dang)漏電(dian)(dian)(dian)電(dian)(dian)(dian)流為(wei)額定漏電(dian)(dian)(dian)電(dian)(dian)(dian)流時，其動作(zuo)時間不應大于0.s。

配電(dian)(dian)箱(xiang)(xiang)是按電(dian)(dian)氣接線要求將開關設(she)備、測(ce)量(liang)儀(yi)表，保(bao)護(hu)電(dian)(dian)器(qi)(qi)和輔助(zhu)設(she)備組裝在封閉或(huo)半封閉金屬柜中或(huo)屏幅上，構成低壓配電(dian)(dian)箱(xiang)(xiang)。正常運行時可借助(zhu)手動(dong)或(huo)自動(dong)開關接通或(huo)分(fen)斷(duan)電(dian)(dian)路。故障或(huo)不(bu)正常運行時借助(zhu)保(bao)護(hu)電(dian)(dian)器(qi)(qi)切斷(duan)電(dian)(dian)路或(huo)報警。借測(ce)量(liang)儀(yi)表可顯示運行中的各種參(can)數(shu)，還可對某些電(dian)(dian)氣參(can)數(shu)進行調整，對偏離(li)正常工(gong)作狀態進行提示或(huo)發出信號(hao)。

配(pei)電(dian)(dian)箱(xiang)是數據上的(de)海量參數，一般是構成(cheng)低(di)壓(ya)林按電(dian)(dian)氣接線，要求(qiu)將開(kai)(kai)關(guan)設備(bei)、測(ce)量儀表(biao)、保護電(dian)(dian)器和輔(fu)助(zhu)設備(bei)組裝在封(feng)(feng)閉或半封(feng)(feng)閉金屬柜中或屏幅上，構成(cheng)低(di)壓(ya)配(pei)電(dian)(dian)箱(xiang)。正常運(yun)行(xing)時可借助(zhu)手動(dong)(dong)或自(zi)動(dong)(dong)開(kai)(kai)關(guan)接通或分(fen)斷電(dian)(dian)路。
