一
、電線和插座接觸不良

在(zai)悉(xi)數(shu)因(yin)電(dian)路(lu)接(jie)觸(chu)不(bu)良(liang)而(er)引(yin)發(fa)的(de)火(huo)災(zai)事(shi)端(duan)中(zhong)，電(dian)線(xian)與(yu)插(cha)座(zuo)接(jie)觸(chu)不(bu)良(liang)是(shi)最(zui)簡(jian)單(dan)發(fa)生(sheng)的(de)。這(zhe)是(shi)由(you)於(yu)當(dang)在(zai)電(dian)路(lu)中(zhong)若(ruo)呈(cheng)現(xian)接(jie)觸(chu)點(dian)不(bu)銜(xian)接(jie)緊(jin)固(gu)的(de)話(hua)

二、電線接線頭接觸不良

、漏電等問題存在。

三
、電器設備本身接觸不良

這樣的情況是有少量電器由於儀器違背接線方法，然後導致線路銜接不結實、或許接頭太熱了使銜接處鬆動並發生氧化而導致電阻過大。
