隨著國網推動使用新型智能電表，越(yue)來越(yue)多的(de)家庭中電表的(de)外側(ce)都會標準5A60A，與之(zhi)前10A40A的(de)電表不同，5A60A的(de)電表精度提升，那么新電表5A60A與老電表10A40A的(de)區別是什么？

新電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)額(e)定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)降低(di)，但電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)提(ti)升，可使用到60安培電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)，老電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)額(e)定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)大，但電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)小(xiao)。那么(me)額(e)定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)5A與10A有(you)(you)何(he)區(qu)別呢？主要是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)的(de)(de)起動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)不(bu)同了，起動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)也就是(shi)(shi)開(kai)始記電(dian)(dian)(dian)(dian)(dian)(dian)(dian)度(du)數的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)，小(xiao)于這(zhe)個(ge)起動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)是(shi)(shi)不(bu)記電(dian)(dian)(dian)(dian)(dian)(dian)(dian)度(du)數的(de)(de)。起動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)是(shi)(shi)額(e)定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)的(de)(de)0.004倍，5×0.004=20毫安，相當于4.4瓦(wa)(wa)，10A表(biao)(biao)剛好(hao)翻倍8.8瓦(wa)(wa)。就是(shi)(shi)說新表(biao)(biao)有(you)(you)4.4瓦(wa)(wa)負荷就開(kai)始記電(dian)(dian)(dian)(dian)(dian)(dian)(dian)度(du)數了，而老表(biao)(biao)要達(da)到8.8瓦(wa)(wa)才開(kai)始記量(liang)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視機、空(kong)調等電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器靜狀功耗(hao)在(zai)3－5瓦(wa)(wa)左右(you)，以(yi)前的(de)(de)老表(biao)(biao)是(shi)(shi)不(bu)記量(liang)的(de)(de)，現在(zai)的(de)(de)新表(biao)(biao)就會(hui)記量(liang)，以(yi)每(mei)家(jia)靜態功耗(hao)8瓦(wa)(wa)算，每(mei)月要耗(hao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)6度(du)，也就是(shi)(shi)說用新表(biao)(biao)后每(mei)月會(hui)增加6度(du)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

因此(ci)在(zai)不用空(kong)調的季節要把插(cha)頭(tou)撥掉(diao)，電(dian)(dian)視(shi)機(ji)關機(ji)時也要拔(ba)插(cha)頭(tou)，或在(zai)裝修時在(zai)床頭(tou)位(wei)置專門設置一個電(dian)(dian)視(shi)機(ji)開關，控制電(dian)(dian)視(shi)機(ji)插(cha)座(zuo)。
