I-Arc Fault Circuit Interrupters (AFCIs)

Ii-Arc-fault circuit interrupters (AFCIs) ziye zafuneka ngokuqinisekileyo ukuze kufakwe kwiindawo zokuhlala phantsi kowama-2002.IKhowudi yoMbane yeSizwe(I-NEC) kwaye ngoku zisetyenziswa kwizicelo ezininzi nangakumbi.Ngokucacileyo, kuye kwaphakanyiswa imibuzo ngokuphathelele ukusetyenziswa kwazo kwanemfuneko yazo.Kubekho iindawo zentengiso, izimvo zobugcisa kwaye, ngokungafihlisiyo, ukungaqondi kwangabom okujikeleza amajelo ohlukeneyo oshishino.Eli nqaku liza kuzisa inyani malunga nokuba zeziphi ii-AFCIs kwaye ngethemba lokuba oku kuya kukwenza uqonde ngcono i-AFCI.

I-AFCI iNqanda imililo yaseKhaya

Kule minyaka ingamashumi amathathu edlulileyo, amakhaya ethu atshintshiwe ngokumangalisayo zizixhobo zombane zanamhlanje kunye nobugcisa obutsha;nangona kunjalo, ezi zixhobo ziye zanegalelo kwinani elikhulu lemililo yombane eli lizwe libandezeleka unyaka nonyaka.Amakhaya amaninzi asele ekhona agxininiswe nje ngeemfuno zombane zanamhlanje ngaphandle kokhuseleko oluhambelanayo lokhuseleko, lubeka umngcipheko omkhulu weempazamo ze-arc kunye nemililo eyenziwa yi-arc.Le yinto esiza kuxoxa ngayo kweli nqaku, abantu kufuneka baphucule izixhobo zabo zombane ukuphucula amanqanaba okhuseleko ngokunjalo.

I-arc fault yingxaki yombane eyingozi ikakhulu ebangelwa ngowonakalisiweyo, ubushushu obugqithisileyo, okanye iingcingo zombane ezicinezelekileyo okanye izixhobo.Iimpazamo ze-arc ngokuqhelekileyo ziya kwenzeka xa iingcingo ezindala ziqhekeka okanye zaqhekeka, xa isikhonkwane okanye isikrufu sisonakalisa ucingo olusemva kodonga, okanye xa iintambo zokuphuma okanye iisekethe zisindwa kakhulu.Ngaphandle kokhuseleko kwizixhobo zombane zamva nje, kuya kufuneka sijonge le miba inokwenzeka kwaye sigcine indlu minyaka le ukuze kubekho uxolo lwengqondo.

Amanani avulekileyo abonisa ukuba iintsilelo ze-arcing zibangela imililo yamakhaya engaphezu kwama-30,000 nyaka ngamnye eUnited States, ephumela ekufeni kwamakhulu abantu nokwenzakala kunye nomonakalo ongaphezu kwezigidi ezingama-750 zeerandi.Isisombululo esinokuthi siphephe ingxaki kukusebenzisa indibaniselwano ye-arc fault circuit interrupter, okanye i-AFCI.I-CPSC iqikelela ukuba i-AFCIs inokuthintela ngaphezu kwe-50 yepesenti yemililo yombane eyenzeka minyaka le.

Ii-AFCI kunye ne-NEC

IKhowudi yeSizwe yoMbane ngokwenene ibandakanye iimfuno ezandisiweyo zokukhusela i-AFCI kuwo onke amakhaya amatsha Ukususela kwi-2008 edition.Nangona kunjalo, la malungiselelo amatsha angasebenzi ngokukhawuleza ngaphandle kokuba ushicilelo lwangoku lweKhowudi yamkelwe ngokusesikweni kwiikhowudi zombane zaseburhulumenteni kunye neendawo.Ukwamkelwa korhulumente kunye nokunyanzeliswa kwe-NEC kunye ne-AFCI yayo esebenzayo ngundoqo ekuthinteleni imililo, ukukhusela amakhaya, kunye nokusindisa ubomi.Ingxaki ingasonjululwa ngokwenene xa bonke abantu besebenzisa ngokuchanekileyo i-AFCI.

Abakhi bezindlu kwamanye amazwe baye bacela umngeni kwiimfuno ezongeziweyo zetekhnoloji ye-AFCI, besithi ezi zixhobo ziya kwandisa kakhulu iindleko zendlu ngelixa zenza umahluko omncinci kakhulu ekuphuculeni ukhuseleko.Ezingqondweni zabo, ukuphucula izixhobo zombane zokhuseleko ziya kwandisa uhlahlo lwabiwo-mali kodwa zinganikezeli ukhuseleko olongezelelweyo lokhuseleko.

Abameli bokhuseleko bacinga ukuba iindleko ezongeziweyo zokhuseleko lwe-AFCI zifanelekile iinzuzo zobuchwephesha ezibonelela umninikhaya.Kuxhomekeka kubungakanani bekhaya elinikiweyo, impembelelo yeendleko zokufakela ukhuseleko olongezelelweyo lwe-AFCI kwikhaya li-$140 – $350, ayiloxabiso elikhulu kakhulu xa lithelekiswa nelahleko enokwenzeka.

Ingxoxo ejikeleze le teknoloji ibangele ukuba amanye amazwe asuse iimfuno ezongezelelweyo ze-AFCI kwikhowudi ngexesha lokwamkelwa.Ngo-2005, i-Indiana yaba lilizwe lokuqala kunye nokuphela kokususa izibonelelo ze-AFCI ezazifakwe kuqala kwikhowudi yombane yelizwe.Sikholelwa ukuba amazwe amaninzi aya kuqalisa ukusebenzisa i-AFCI njengokhuseleko olutsha ngokusasazwa kobuchwepheshe.
