NgokweMigangatho yokuSebenza yoHlolo lweKhaya loMbane ngokubanzi, “Umhloli uya kuhlola zonke izixhobo zokuphazamiseka kwesekethe eziphantsi komhlaba kunye nezaphuli zesekethe ezijongwayo kwaye zithathwa ngokuba zii-GFCIs zisebenzisa umvavanyi we-GFCI, apho kunokwenzeka… kwaye ahlole inani elimele lokutshintsha, izibane zokukhanyisa. kunye nezixhobo, kubandakanywa nezixhobo ezibonwayo nezithathwa njenge-arc-fault circuit interrupter (AFCI)-ezikhuselweyo kusetyenziswa iqhosha lovavanyo le-AFCI, apho kunokwenzeka.”Abahloli bamakhaya kufuneka baziqhelanise nolu lwazi lulandelayo ukuze baqonde ngakumbi indlela yokuqhuba uhlolo olufanelekileyo nolucokisekileyo lwee-GFCIs kunye nee-AFCI.
Iziseko
Ukuqonda ii-GFCIs kunye nee-AFCIs, kuyanceda ukwazi iinkcazo ezimbalwa.Isixhobo yinxalenye yesixokelelwano sombane, asilulo ucingo lwekhondaktara, oluthwala okanye olulawula umbane.Ukutshintsha ukukhanya ngumzekelo wesixhobo.I-outlet yindawo kwi-wiring system apho ikhoyo ngoku ifikeleleke ukubonelela ngezixhobo.Umzekelo, umatshini wokuhlamba izitya unokudityaniswa kwindawo yokuphuma ngaphakathi kwikhabhinethi ye-sink.Elinye igama lesixhobo sombane sisixhobo sombane.
Yintoni i-GFCI?
Isiphazamisi sesekethe ye-fault-fault, okanye i-GFCI, sisixhobo esisetyenziswa kwiintambo zombane ukuqhawula isekethe xa kufunyanwa umsinga ongalungelelananga phakathi komqhubi onamandla kunye nomqhubi wokubuyisela ongathathi hlangothi.Ukungalingani okunjalo ngamanye amaxesha kubangelwa "ukuvuza" kwangoku ngomntu odibana nomhlaba kunye nenxalenye enamandla yesekethe, enokubangela ukutshatyalaliswa okubulalayo.Ii-GFCI zenzelwe ukubonelela ngokhuseleko kwimeko enjalo, ngokungafaniyo nabaqhekezi beesekethe eziqhelekileyo, ezikhusela ukugqithiswa, iisekethe ezimfutshane kunye neziphene zomhlaba.
Yintoni i-AFCI?
I-Arc-fault circuit interrupters (AFCIs) ziintlobo ezikhethekileyo zezixhobo zombane okanye ii-outlet kunye nee-breaker circuits ezenzelwe ukufumanisa nokuphendula kwii-arcs zombane ezinokuthi zibe yingozi kwi-wiring yesebe lasekhaya.Njengoko ziyilelwe, ii-AFCIs zisebenza ngokubeka iliso kwindlela yombane kunye nokuvula ngokukhawuleza (ukuphazamisa) isiphaluka abasisebenzelayo ukuba bafumanisa utshintsho kwipatheni yamaza oluphawu lwe-arc eyingozi.Ukongeza ekufumaneni iipateni zamaza ayingozi (ii-arcs ezinokubangela umlilo), ii-AFCIs nazo zenzelwe ukwahlula ii-arcs ezikhuselekileyo, eziqhelekileyo.Umzekelo wale arc kuxa iswitshi ivuliwe okanye iplagi itsalwa kwi-receptacle.Utshintsho oluncinci kakhulu kwiipateni zamaza lunokubonwa, luqatshelwe, kwaye luphendulwe zii-AFCIs.
IiMfuno zeKhowudi yokuHlala yaMazwe ngaMazwe yowama-2015 (IRC) yee-GFCIs kunye nee-AFCI
Nceda ujonge iCandelo E3902 le-IRC ka-2015 elinxulumene nee-GFCIs kunye nee-AFCIs.
Ukhuseleko lwe-GFCI luyacetyiswa koku kulandelayo:
- I-15- kunye ne-20-amp izixhobo ze-countertop zasekhitshini kunye neendawo zokuhlamba izitya;
- I-15- kunye ne-20-amp yokuhlambela kunye nempahla yokuhlamba impahla;
- 15- kunye ne-20-amp izixhobo ngaphakathi kweenyawo ezi-6 kumphetho wangaphandle wesitya, ibhafu okanye ishawari;
- imigangatho efudunyezwe ngombane kumagumbi okuhlambela, ekhitshini, nakwiibhafu ze-hydromassage, iindawo zokuhlambela, kunye neebhafu ezishushu;
- I-15- kunye ne-20-amp yezixhobo zangaphandle, ekufuneka zibe nokhuseleko lwe-GFCI, ngaphandle kwezixhobo ezingafikeleleki lula ezisetyenziselwa izixhobo zokunyibilikisa ikhephu zethutyana kwaye zikwisekethe ezinikeleyo;
- I-15- kunye ne-20-amp izixhobo kwiigaraji kunye nezakhiwo zokugcina ezingagqitywanga;
- I-15- kunye ne-20-amp izixhobo kwi-boathouses kunye ne-240-volt kunye neendawo zokuthengisa ezincinci kwiindawo zokukhwela izikhephe;
- 15- kunye ne-20-amp izikhongozeli kumagumbi angaphantsi angagqitywanga, ngaphandle kwezixhobo zomlilo okanye iialam zokuqhekeza;kwaye
- 15- kunye ne-20-amp izikhongozeli kwiindawo zokukhwela kumphakamo okanye ngaphantsi komhlaba.
Ii-GFCIs kunye nee-AFCIs kufuneka zifakwe kwiindawo ezifikeleleka lula kuba zinamaqhosha ovavanyo ekufuneka etyhalwe ngamaxesha athile.Abavelisi bacebisa ukuba abanini-zindlu kunye nabahloli bavavanye okanye bajikelise izaphuli-mthetho kunye nezixhobo ngamaxesha athile ukuze bancede baqinisekise ukuba izinto zombane zisebenza kakuhle.
Ukukhuselwa kwe-AFCI kucetyiswa kwi-15- kunye ne-20-amp amp kwiisekethe zesebe kumagumbi okulala, ii-closets, i-dens, amagumbi okudlela, amagumbi osapho, iipaseji, iikhikhini, iindawo zokuhlambela, iilayibrari, amagumbi okuhlala, ii-parlor, amagumbi okuzonwabisa, kunye namagumbi elanga.
Amagumbi afanayo okanye iindawo mazikhuselwe yiyo nayiphi na kwezi zilandelayo:
- udidi oludityanisiweyo lwe-AFCI olufakelweyo kwisekethe yesebe lonke.I-NEC ka-2005 yayifuna ii-AFCIs zodidi oludityanisiweyo, kodwa ngaphambi komhla woku-1 kuJanuwari ka-2008, kwasetyenziswa ii-ACIs zesebe/nohlobo lwe-feeder.
- isebe/i-feeder-uhlobo lwe-ACCI i-breaker efakwe kwiphaneli ngokudibanisa ne-AFCI ye-receptacle kwibhokisi yokuqala yokuphuma kwisekethe.
- i-arc-protection circuit breaker (engasaveliswanga) efakwe kwindawo yolawulo ngokudityaniswa nesixhobo se-AFCI esifakwe kwindawo yokuphuma yokuqala, apho zonke ezi meko zilandelayo zihlangatyezwana nazo:
- i-wiring iyaqhubeka phakathi kwe-breaker kunye ne-AFCI yokuphuma;
- ubude obude be-wiring abukho ngaphezu kweenyawo ze-50 kwi-14-gauge wire, kunye ne-70 yeenyawo ze-12-gauge wire;kwaye
- ibhokisi yokuphuma yokuqala iphawulwe njengendawo yokuqala yokuphuma.
- Isingxobo esidwelisiweyo se-AFCI esifakwe kwindawo yokuqala yokuphuma kwisekethe ngokudityaniswa nesixhobo esidwelisiweyo sokhuselo olungaphaya kolwandle, apho zonke ezi meko zilandelayo zihlangatyezwana nazo:
- i-wiring iyaqhubeka phakathi kwesixhobo kunye ne-receptacle;
- ubude obude be-wiring abukho ngaphezu kweenyawo ze-50 kwi-14-gauge wire kunye ne-70 yeenyawo ze-12-gauge wire;
- indawo yokuphuma yokuqala iphawulwe njengendawo yokuqala yokuphuma;kwaye
- indibaniselwano yesixhobo sokhuseleko olugqithileyo kunye nesixhobo se-AFCI zichongiwe njengokuhlangabezana neemfuno zodidi oludityanisiweyo lwe-AFCI.
- isitya se-AFCI kunye nendlela yokufaka iintambo zentsimbi;kwaye
- Isixhobo se-AFCI kunye nekhonkrithi evalekileyo.
Isishwankathelo
Ngamafutshane, ukuqinisekisa ukuba izaphuli zesekethe kunye nezixhobo zokusebenza zisebenza ngokufanelekileyo, abaninimzi kunye nabahloli bamakhaya kufuneka ngamaxesha athile bajikeleze okanye bavavanye amalungu ombane ukuba asebenze ngokufanelekileyo.Uhlaziyo lwakutsha nje lwe-IRC lufuna ukhuseleko oluthe ngqo lwe-GFCI kunye ne-AFCI ye-15- kunye ne-20-amp yezixhobo.Abahloli bamakhaya kufuneka baziqhelanise nezi zikhokelo zitsha ukuqinisekisa uvavanyo olufanelekileyo kunye nokuhlolwa kwee-GFCIs kunye nee-AFCIs.
