Chifukwa chiyani maziko ndi ofunikira pa zotengera
Zitsulo (magetsi ogulitsira magetsi) omwe ali ndi zigawo ziwiri zokha zimatchedwa zotengera zopangira polarized . Izi zili ndi chigawo chochepa cha "hot" komanso chigawo chachikulu chotenga mbali, kuonetsetsa kuti mitsinje yamagetsi ikuyenda pamtunda woyenera mu dera; kutenthetsa, kusalowerera ndale. Zipangizo zamakono zamakono zili ndi mapiritsi apakati ndi opapatiza, kapena masamba kuti muthe kukwera mu cholumikizira njira imodzi yokha.
Izi zonse ndi mbali ya chitetezo chomwe chakhala chikugwiritsidwa ntchito kwambiri kuyambira m'ma 1920. Zomwe zilili lero zimakhala ndi malo atatu - otentha, osalowerera ndale, ndi nthaka - ndi kulandira mapulagi omwe amagwiritsa ntchito katatu . Powongoka bwino, izi zimapereka malo odalirika omwe ali otetezeka kusiyana ndi machitidwe akale omwe ali ndi zida zowonongeka.
Kufunika Kokhala pansi
Kukhazikitsa pansi ndiko njira yotetezera yomwe imapereka njira yowonjezera magetsi kuti ipite ku malo abwino ngati pali vuto ndi dera. Mwachitsanzo, ngati waya atuluka kuchokera ku chokwanira ndikugwiritsira mbali ya bwalo lamagetsi, magetsi amatha kudutsa mu bokosilo komanso pamtunda womwe uli pansi pa bokosi, ndipo pamapeto pake amachoka bwinobwino padziko lapansi kunja kwa nyumba. Chinthu chomwecho chikhoza kuchitika ndi waya wotayirira mkati mwa chipangizo chojambulidwa kapena chipangizo china. Chifukwa chakuti zotengera za polarized zilibe malo otsetsereka, sizikhoza kupereka njira yapansi pakati pa chipangizo chogwiritsira ntchito chogwiritsira ntchito ndi magetsi.
Ndipotu, zimbudzi zomwe zimapezeka m'nyumba zambiri sizongowonjezera chifukwa dongosololi liribe malo enieni.
Njira Zogwiritsa Ntchito
Zosungira katundu m'mabumba akuluakulu zingatheke kapena zisagwirizane ndi madera ozungulira. Ngati cholowacho chikaikidwa mu bokosi lachitsulo chomwe chimagwirizanitsidwa ndi chingwe chachitsulo (cholimba kapena chosasinthika), chombocho chikhoza kuperekedwa kudzera mu bokosi ndi kutsogolo (koma kachiwiri, sichikhoza kukhazikitsa chipangizo cholowetsedwa).
Ndi mtundu uwu wa pulogalamu, pangakhale mawaya akuda ndi akuda okha. Palibe waya wothandizira chifukwa bokosi lachitsulo ndi dzira zimapereka njira. Komabe, dongosolo la nthaka liyenera kukhala lopitirira kubwerera kuntchito yapakhomo (bokosi losweka) kuti dongosolo la nthaka lisinthe. Mu machitidwe ena, ngati bokosi la cholandirira silili chitsulo kapena ngati palibe zitsulo, palibe malo ozungulira. Nyumba zambiri zakhazikitsidwa m'ma 1950, mwachitsanzo, zakhala ndi mabotolo a zitsulo ndi waya wodutsitsa wa 2 wosakhala ndi waya. Machitidwe awa alibe maziko.
Kusintha Zinthu Zowononga Polarized
Ngati makina anu a dera akuphatikizapo nthaka, kungosintha zida zakale zowonongeka ndi zitsulo zatsopano zowonongeka zitatu zidzakupatsani zitsulo zokhazikika. Ngati maulendo alibe malo, kukhazikitsa zogulitsira pansi sizingapereke malo. Idzakulolani kuti mutsegule mapulogi a 3-prong, koma sipadzakhala chitetezo pamtunda. Njira yabwino yoperekera nthaka ndiyo kuyendetsa dera ndi chingwe chokhazikika ndi kukhazikitsa zatsopano. Njira ina yomwe imapangitsa kuti pakhale chitetezo koma imapereka malo oti mutenge malo obwezeretsedwa ndi GFCI . GFCI idzazindikira cholakwika, ngati chachidule mu chogwiritsira ntchito, ndi kutseka mphamvu pa cholandirira, kuchotsa mphamvu zowonjezera.
Komabe, sizingawonjezeko pansi pa cholandira kapena dera.
