Arc Fault Circuit Interrupters (AFCIs)

Ma Arc-fault circuit interrupters (AFCIs) akhala akufunika kuti akhazikitsidwe m'nyumba zomwe zili pansi pa 2002.National Electrical Code(NEC) ndipo pakali pano amagwiritsidwa ntchito mochulukirachulukira.Mwachionekere, mafunso abuka ponena za kugwiritsiridwa ntchito kwawo ndi ngakhale kufunika kwa iwo.Pakhala pali zotsatsa, malingaliro aukadaulo ndipo, kunena zoona, kusamvetsetsana mwadala komwe kumayandama panjira zosiyanasiyana zamakampani.Nkhaniyi ifotokoza zowona za ma AFCI ndipo mwachiyembekezo izi zipangitsa kuti mumvetsetse bwino za AFCI.

AFCI Amaletsa Moto Kunyumba

Kwa zaka makumi atatu zapitazi, nyumba zathu zasinthidwa kwambiri ndi zipangizo zamakono zamakono ndi zamakono zamakono;komabe, zipangizozi zathandiziranso kuti chiwerengero chachikulu cha moto wamagetsi dziko lino likuvutikira chaka ndi chaka.Nyumba zambiri zomwe zilipo zimangogwedezeka ndi zofuna zamagetsi zamakono popanda chitetezo chogwirizana, zomwe zimawaika pachiwopsezo chachikulu cha zolakwika za arc ndi moto wopangidwa ndi arc.Izi ndi zomwe tikambirana m'nkhaniyi, anthu akuyenera kukweza zida zawo zamagetsi kuti apititse patsogolo chitetezo.

Kuwonongeka kwa arc ndi vuto lamagetsi lowopsa makamaka chifukwa cha mawaya owonongeka, kutenthedwa, kapena kupsinjika kwa mawaya amagetsi kapena zida.Kuwonongeka kwa ma arc kumachitika nthawi zambiri mawaya akale akaphwanyika kapena kusweka, msomali kapena wononga waya kuseri kwa khoma, kapena mabwalo akalemedwa kwambiri.Popanda chitetezo kuzipangizo zamakono zamakono, tiyenera kuyang'ana izi zomwe zingatheke ndikusamalira nyumba chaka chilichonse kuti mukhale ndi mtendere wamumtima.

Ziŵerengero zapoyera zimasonyeza kuti kuvulala kwa mabwalo kumachititsa moto wa nyumba zoposa 30,000 chaka chilichonse ku United States, kupha mazana ambiri a imfa ndi kuvulala ndi kuwononga katundu woposa $750 miliyoni.Yankho lomwe lingapewere vuto ndikugwiritsa ntchito chophatikizira cha arc fault circuit interrupter, kapena AFCI.CPSC ikuyerekeza kuti ma AFCI amatha kuteteza kupitilira 50 peresenti yamoto wamagetsi womwe umachitika chaka chilichonse.

AFCI ndi NEC

National Electrical Code yaphatikizanso zofunikira zowonjezera chitetezo cha AFCI m'nyumba zonse zatsopano Kuyambira kope la 2008.Komabe, zinthu zatsopanozi sizigwira ntchito nthawi yomweyo pokhapokha ngati buku lomwe lilipo pano la Code livomerezedwa kukhala ma code amagetsi aboma ndi akumaloko.Kukhazikitsidwa kwa boma ndi kulimbikitsa NEC ndi AFCI yake yokhazikika ndikofunikira pakuletsa moto, kuteteza nyumba, ndi kupulumutsa miyoyo.Vuto litha kuthetsedwa ngati anthu onse akugwiritsa ntchito AFCI molondola.

Omanga nyumba m'maboma ena adatsutsa zofunikira zowonjezera zaukadaulo wa AFCI, ponena kuti zida izi zidzakulitsa kwambiri mtengo wanyumba pomwe zikupanga kusiyana kochepa pakuwongolera chitetezo.M'malingaliro awo, kukweza zida zamagetsi zamagetsi kumawonjezera bajeti koma osapereka chitetezo chowonjezera.

Olimbikitsa chitetezo amaganiza kuti mtengo wowonjezera wachitetezo cha AFCI ndi wofunika kwambiri ndi mapindu omwe ukadaulo umapereka kwa eni nyumba.Kutengera ndi kukula kwa nyumba yomwe yapatsidwa, mtengo wake pakuyika chitetezo chowonjezera cha AFCI mnyumba ndi $140 - $350, si mtengo waukulu kwambiri poyerekeza ndi kutayika komwe kungatheke.

Mkangano wokhudzana ndi ukadaulo uwu wapangitsa kuti mayiko ena achotse zofunikira za AFCI pama code panthawi yokhazikitsidwa.Mu 2005, Indiana idakhala dziko loyamba komanso lokhalo kuchotsa zinthu za AFCI zomwe zidaphatikizidwa m'makhodi amagetsi a boma.Tikukhulupirira kuti mayiko ochulukirapo ayamba kugwiritsa ntchito AFCI ngati chitetezo chaposachedwa kwambiri ndi kutchuka kwaukadaulo.
