大連配電箱(柜)、開關箱裝置(zhi)使用(yong)應契合《施工現(xian)場暫(zan)時(shi)用(yong)電(dian)安全技(ji)術(shu)規(gui)范》JGJ46-2005 規(gui)范及(ji)《用(yong)電(dian)安全導(dao)則(ze)》GB/T13869 規(gui)范化要(yao)求。

    穿管(guan)布線(xian)時(shi)，大(da)連(lian)配電箱固定點(dian)間隔不(bu)(bu)該超越1米(mi)(mi)，導(dao)線(xian)絕(jue)緣(yuan)(yuan)等級不(bu)(bu)得低于(yu)交流 750V，與(yu)煤氣管(guan)道的(de)凈(jing)距不(bu)(bu)小于(yu)0.5米(mi)(mi); 與(yu)水管(guan)平(ping)行(xing)敷設(she)時(shi)，宜在水管(guan)的(de)上(shang)方， 凈(jing)距不(bu)(bu)小于(yu)0.1米(mi)(mi);3根(gen)以(yi)上(shang)絕(jue)緣(yuan)(yuan)導(dao)線(xian)穿同一(yi)根(gen)管(guan)時(shi)，導(dao)線(xian)的(de)總截面積不(bu)(bu)該大(da)于(yu)管(guan)內(nei)凈(jing)面積的(de)40%，2根(gen)絕(jue)緣(yuan)(yuan)導(dao)線(xian)穿同一(yi)根(gen)管(guan)時(shi)，管(guan)內(nei)徑不(bu)(bu)該小于(yu)2根(gen)導(dao)線(xian)直徑之和的(de) 1.35 倍(bei)。

    進戶線(xian)(xian)沿(yan)建筑物外(wai)墻敷設時，應(ying)與墻角、屋(wu)檐等外(wai)觀走向保持一致， 避開廚房(fang)排氣(qi)扇、空(kong)調外(wai)機等有高溫輻射或對絕緣層有腐蝕的(de)方位。大連配電(dian)箱(柜)、開關(guan)箱應(ying)分設N 線(xian)(xian)、PE 線(xian)(xian)端(duan)(duan)子(zi)板(ban)(ban)，進出(chu)線(xian)(xian)經過端(duan)(duan)子(zi)板(ban)(ban)做牢(lao)靠(kao)銜(xian)(xian)接(jie)(jie)。N 線(xian)(xian)端(duan)(duan)子(zi)板(ban)(ban)要與金屬(shu)電(dian)器裝(zhuang)置板(ban)(ban)絕緣;PE 線(xian)(xian)端(duan)(duan)子(zi)板(ban)(ban)與金屬(shu)電(dian)器裝(zhuang)置板(ban)(ban)做電(dian)氣(qi)銜(xian)(xian)接(jie)(jie)。進出(chu)線(xian)(xian)中的(de)N 線(xian)(xian)經過N 線(xian)(xian)端(duan)(duan)子(zi)板(ban)(ban)銜(xian)(xian)接(jie)(jie);PE 線(xian)(xian)有必要經過PE 線(xian)(xian)端(duan)(duan)子(zi)板(ban)(ban)銜(xian)(xian)接(jie)(jie)。PE 線(xian)(xian)與端(duan)(duan)子(zi)板(ban)(ban)銜(xian)(xian)接(jie)(jie)選用電(dian)氣(qi)銜(xian)(xian)接(jie)(jie)。
