AFCI yog lub tshuab hluav taws xob siab tshaj plaws uas yuav ua rau lub voj voog tawg thaum nws pom cov hluav taws xob txaus ntshai nyob hauv Circuit Court uas nws tiv thaiv.
Ib qho AFCI tuaj yeem xaiv qhov txawv yog tias nws yog qhov tsis muaj teeb meem arc uas yog teeb meem rau kev ua haujlwm ntawm cov keyboards thiab cov ntsaws ruaj ruaj los yog qhov muaj peev xwm txaus ntshai arc uas tuaj yeem tshwm sim, xws li hauv lub teeb qaum nrog tus neeg xyuas pib tawg.AFCI yog tsim los qhia txog ntau yam ntawm arcing hluav taws kev ua txhaum uas pab txo qhov hluav taws xob los ntawm qhov hluav taws kub.
Txawm hais tias AFCIs tau qhia thiab sau rau hauv cov lej hluav taws xob nyob rau xyoo 1990s (yuav tham txog cov ntsiab lus ntxiv tom qab), ntau cov lus dab neeg tseem nyob ib puag ncig AFCIs - cov lus dab neeg feem ntau ntseeg los ntawm cov tswv tsev, cov neeg tsim cai lij choj hauv lub xeev, cov thawj coj hauv tsev, thiab txawm tias qee tus kws hluav taws xob.
MYTH 1:AFCI tsis yogso tseem ceeb thaum nws los cawm txoj sia
"AFCIs yog cov cuab yeej muaj kev nyab xeeb tseem ceeb heev uas tau ua pov thawj ntau zaus," said Ashley Bryant, tus thawj tswj hwm khoom lag luam loj rau Siemens.
Arc faults yog ib qho ntawm cov laj thawj tseem ceeb ntawm hluav taws xob hluav taws xob hauv tsev.Los ntawm xyoo 1990, raws li US Consumer Product Safety Commission (CPSC), qhov nruab nrab ntawm ntau dua 40,000 hluav taws kub hauv ib xyoos yog vim muaj hluav taws xob hauv tsev, ua rau ntau dua 350 tus neeg tuag thiab ntau dua 1,400 raug mob.CPSC kuj tau tshaj tawm tias ntau dua 50 feem pua ntawm cov hluav taws kub no tuaj yeem tiv thaiv thaum siv AFCIs.
Tsis tas li ntawd, CPSC tshaj tawm tias hluav taws xob hluav taws xob vim yog arcing feem ntau tshwm sim tom qab phab ntsa, ua rau lawv txaus ntshai.Ntawd yog, cov hluav taws kub no tuaj yeem kis tsis tau sai dua, yog li lawv tuaj yeem ua rau muaj kev puas tsuaj ntau dua li lwm qhov hluav taws kub, thiab lawv xaus rau ob zaug li qhov hluav taws kub tsis tshwm sim tom qab phab ntsa, vim cov tswv tsev tsis paub txog qhov hluav taws kub tom qab phab ntsa kom txog thaum nws tuaj yeem ua rau hluav taws kub. yuav lig dhau mus.
MYTH 2:AFCI cov tuam txhab tau tsav tsheb nthuav dav cov cai rau kev teeb tsa ntawm AFCI
"Kuv pom cov lus dab neeg no tshwm sim thaum kuv tham nrog cov neeg tsim cai lij choj, tab sis kev lag luam hluav taws xob yuav tsum nkag siab qhov tseeb ib yam nkaus thaum lawv tham nrog lawv cov neeg sawv cev hauv xeev thiab cov thawj coj hauv tsev," said Alan Manche, tus lwm thawj, cov haujlwm sab nraud, rau Schneider Electric. .
Tiag tiag tus tsav rau qhov kev xav tau nthuav dav yog los ntawm kev tshawb fawb thib peb.
Consumer Product Safety Commission thiab cov kev tshawb fawb ua los ntawm UL hais txog ntau txhiab qhov hluav taws kub tshwm sim hauv tsev nyob rau xyoo 1980s thiab thaum ntxov 1990s tau tsav los xyuas seb qhov ua rau hluav taws kub no.Arc txhaum kev tiv thaiv tau dhau los ua cov tshuaj uas tau lees paub los ntawm CPSC, UL, thiab lwm yam.
MYTH 3:AFCIs tsuas yog xav tau los ntawm cov lej hauv cov chav me me hauv cov tsev nyob
Jim Phillips, PE tus thawj tswj hwm ntawm Brainfiller.com tau hais tias "Lub Tebchaws Hluav Taws Xob Txoj Cai tau nthuav dav mus txog AFCIs dhau ntawm cov tsev nyob."
Thawj Txoj Cai Hluav Taws Xob Hauv Tebchaws (NEC) yuav tsum tau ua rau AFCIs tso tawm xyoo 1999 xav kom lawv tau teeb tsa los tiv thaiv cov vaj huam sib luag pub chav pw hauv tsev tshiab.Hauv xyoo 2008 thiab 2014, NEC tau nthuav dav kom xav tau AFCIs los nruab rau hauv circuits rau ntau thiab ntau chav hauv tsev, tam sim no suav nrog txhua chav - chav pw, tsev neeg chav, chav noj mov, chav nyob, chav hnub ci, chav ua noj, qhov chaw, chaw ua haujlwm hauv tsev. , chav tsev, chav ua si, chav ntxhua khaub ncaws, thiab txawm tias txee dai khaub ncaws.

MYTH 4:AFCI tsuas yog tiv thaiv dab tsi yog ntsaws rau hauv lub qhov hluav taws xob tshwj xeeb uas ua rau hluav taws xob arc
"Ib qho AFCI tiag tiag tiv thaiv tag nrho lub voj voog tsis yog tsuas yog covtshwj xeeb qhov hluav taws xob tsis zoo uas ua rau hluav taws xob arc, "hais tias Rich Korthauer, tus lwm thawj, kev lag luam xa tawm zaum kawg, rau Schneider Electric."Suav nrog lub vaj huam sib luag hluav taws xob, cov xaim xaim xaim xaim xaim xaim xaim los ntawm cov phab ntsa, lub qhov hluav taws xob, cov keyboards, tag nrho cov kev sib txuas rau cov xov hlau, qhov hluav taws xob thiab cov hluav taws xob, thiab txhua yam uas txuas rau hauv ib qho ntawm cov qhov hluav taws xob thiab txuas nrog cov keyboards ntawm lub Circuit Court. ”
MYTH 5:Tus txheej txheem Circuit Court breaker yuav muab kev tiv thaiv ntau npaum li AFCI
Cov neeg xav tias tus qauv breaker yuav muab kev tiv thaiv ntau npaum li AFCI, tab sis qhov tseeb, cov pa hluav taws xob tsuas yog teb rau overloads thiab luv circuits.Lawv tsis tiv thaiv arcing tej yam kev mob uas tsim erratic thiab feem ntau txo tam sim no.
Tus txheej txheem Circuit Court breaker tiv thaiv cov rwb thaiv tsev ntawm cov xaim los ntawm kev tshaj tawm, nws tsis yog tsim los txheeb xyuas qhov tsis zoo ntawm cov kab hluav taws xob hauv tsev.Tau kawg, tus qauv Circuit Court breaker yog tsim los mus ncig thiab cuam tshuam qhov xwm txheej yog tias koj muaj luv luv.
MYTH 6:Feem ntau AFCI "trips"tshwm sim vim lawvyog "kev nyuaj siab ntxhov plawv"
Siemens 'Bryant tau hais tias nws hnov cov lus dab neeg no ntau heev."Tib neeg xav tias qee qhov arc txhaum breakers yog qhov tsis xws vim lawv nquag mus ncig.Tib neeg yuav tsum xav txog cov no yog kev ceeb toom kev nyab xeeb es tsis yog kev tsis txaus siab.Feem ntau ntawm cov sij hawm, cov breakers mus txawv tebchaws vim lawv yuav tsum.Lawv tab tom taug kev vim qee yam kev tshwm sim arcing ntawm lub voj voog. "
Qhov no tuaj yeem muaj tseeb nrog "stab" receptacles, qhov twg cov xov hlau yog lub caij nplooj ntoos hlav-loaded rau hauv qab ntawm lub receptacles tsis thaiv ib ncig ntawm screws, uas muab kev sib txuas ruaj khov.Feem ntau, thaum cov tswv tsev jam ntsaws rau hauv lub caij nplooj ntoos hlav-loaded receptacles los yog rub tawm roughly, nws feem ntau jostles lub receptacles, cia cov xov hlau los xoob, uas yuav ua rau lub arc txhaum breakers mus txawv tebchaws.
