Ngokuya Ngamazinga Okusebenza Ajwayelekile Okuhlola Ikhaya Lasekhaya Kagesi, “Umhloli uzohlola zonke izinto ezisetshenziswayo zesiphazamisi sesekethe esinephutha eliphansi kanye nama-breaker circuit abonwa futhi athathwe njengama-GFCI kusetshenziswa isihloli se-GFCI, lapho kungenzeka khona… futhi ahlole inombolo emele amaswishi, izinto zokukhanyisa. kanye nezimpahla, okuhlanganisa nezinto ezibonwayo nezithathwa njenge-arc-fault circuit interrupter (AFCI) -ezivikelwe kusetshenziswa inkinobho yokuhlola ye-AFCI, lapho kungenzeka khona.”Abahloli basekhaya kufanele bazijwayeze ngolwazi olulandelayo ukuze baqhubeke baqonde ukuthi kwenziwa kanjani ukuhlola okufanele nokucophelela kwama-GFCI nama-AFCI.
Izisekelo
Ukuze uqonde ama-GFCI nama-AFCI, kuyasiza ukwazi izincazelo ezimbalwa.Umshini uyingxenye yesistimu kagesi, hhayi intambo yekhondatha, ethwala noma elawula ugesi.Ukushintsha ukukhanya kuyisibonelo sedivayisi.I-outlet yindawo ohlelweni lwezintambo lapho i-current ifinyeleleka ekuhlinzekeni okokusebenza.Isibonelo, umshini wokuwasha izitsha ungase uxhunywe endaweni yokuphuma ngaphakathi kwekhabethe likasinki.Elinye igama le-outlet kagesi isitsha sikagesi.
Yini i-GFCI?
Isiphazamisi sesekethe esinephutha eliphansi, noma i-GFCI, iyithuluzi elisetshenziswa ezintamboni zikagesi ukuze kunqanyulwe isekethe lapho kutholwa igagasi elingalingani phakathi kwe-conductor enamandla kanye nekhondatha yokubuyisela emaphakathi.Ukungalingani okunjalo ngezinye izikhathi kubangelwa "ukuvuza" kwamanje ngomuntu othintana nomhlabathi kanye nengxenye enamandla yesifunda, okungabangela ukushaqeka okubulalayo.Ama-GFCI adizayinelwe ukunikeza ukuvikeleka esimweni esinjalo, ngokungafani nezinqamuli zesekethe ezijwayelekile, ezivikela ukugcwala ngokweqile, amasekhethi amafushane namaphutha aphansi.
Iyini i-AFCI?
Iziphazamisi zesekethe ze-Arc-fault (AFCIs) ziyizinhlobo ezikhethekile zezimpahla zikagesi noma izitolo kanye nama-breaker circuit aklanyelwe ukuthola nokusabela kuma-arcs kagesi angaba yingozi kuzintambo zegatsha lasekhaya.Njengoba yakhelwe, ama-AFCI asebenza ngokuqapha i-wave wave kagesi futhi avule ngokushesha (ukuphazamisa) isekethe ayinikezayo uma ebona izinguquko kuphethini yegagasi ewuphawu lwe-arc eyingozi.Ngokungeziwe ekutholweni kwamaphethini amagagasi ayingozi (ama-arcs angase abangele imililo), ama-AFCI aphinde aklanyelwe ukuhlukanisa ama-arcs aphephile, avamile.Isibonelo sale arc yilapho iswishi ivuliwe noma ipulaki idonswa esitsheni.Izinguquko ezincane kakhulu kumaphethini wamagagasi zingatholwa, zibonwe, futhi ziphendulwe ama-AFCI.
2015 Izimfuneko Zekhodi Yendawo Yokuhlala Yamazwe Ngamazwe (IRC) yama-GFCI nama-AFCI
Sicela ubhekisele kuSigaba E3902 se-IRC yango-2015 esihlobene nama-GFCI nama-AFCI.
Ukuvikelwa kwe-GFCI kunconyelwe lokhu okulandelayo:
- 15- kanye ne-20-amp ama-amp countertop asekhishini kanye nezitolo zokugeza izitsha;
- 15- kanye ne-20-amp yokugezela kanye nempahla yokuwasha;
- 15- kanye no-20-amp amafidi ngaphakathi kwamafidi angu-6 onqenqemeni lwangaphandle lukasinki, ubhavu wokugeza noma ishawa;
- izitezi ezishisiswe ngogesi ezindlini zokugezela, emakhishini, nakumabhavu e-hydromassage, eziphaleni, namabhavu ashisayo;
- I-15- kanye ne-20-amp yezimpahla zangaphandle, okufanele zibe nesivikelo se-GFCI, ngaphandle kwezimpahla ezingafinyeleleki kalula ezisetshenziselwa okokusebenza kwesikhashana okuncibilika iqhwa futhi zikusekhethi ezinikele;
- I-15- kanye ne-20-amp receptacles emagaraji nezakhiwo zokugcina ezingaqediwe;
- 15- kanye no-20-amp amp ezindlini zezikebhe kanye nama-240-volt kanye nezindawo zokuthengisa ezincane ezindaweni ezikhuphula izikebhe;
- 15- kanye nezingu-20-amp ezifakwa ezindlini ezingaphansi ezingaqediwe, ngaphandle kwezindawo zokubeka umlilo noma ama-alamu okugqekeza;futhi
- Izimpahla ezingu-15- kanye nezingu-20-amp ezindaweni zokucaca ezingeni eliphansi noma ngaphansi.
Ama-GFCI nama-AFCI kufanele afakwe ezindaweni ezifinyeleleka kalula ngoba anezinkinobho zokuhlola okufanele ziphushwe ngezikhathi ezithile.Abakhiqizi batusa ukuthi abanikazi bezindlu nabahloli bahlole noma bajikelezise izinqamuleli nezitsha ngezikhathi ezithile ukuze basize ukuqinisekisa ukuthi izingxenye zikagesi zisebenza kahle.
Ukuvikelwa kwe-AFCI kunconywa ezindaweni ezingu-15 no-20-amp kumasekethe egatsha emakamelweni okulala, ama-closet, ama-dens, amagumbi okudlela, amagumbi omndeni, amaphasishi, amakhishi, izindawo zokuwasha, imitapo yolwazi, amagumbi okuhlala, ama-parlor, amagumbi okungcebeleka, namakamelo elanga.
Amakamelo noma izindawo ezifanayo kufanele zivikelwe yinoma yikuphi kokulandelayo:
- inhlanganisela yohlobo lwe-AFCI efakwe kuyo yonke isifunda segatsha.I-NEC yango-2005 yayidinga ama-AFCI ohlobo oluhlanganisiwe, kodwa ngaphambi komhla lu-1 kuJanuwari, 2008, kwasetshenziswa ama-AFCI egatsha/ohlobo lokuphakelayo.
- isinqamuli segatsha/sohlobo lokuphakelayo se-AFCI esifakwe kuphaneli sihlanganiswe nesitsha se-AFCI ebhokisini lokuqala lokuphuma kusekethe.
- i-supplemental arc-protection circuit breaker (engasakhiqizwa) efakwe kuphaneli ihlanganiswe nesitsha se-AFCI esifakwe endaweni yokuqala yokukhipha, lapho zonke lezi zimo ezilandelayo zihlangatshezwana nazo:
- i-wiring iyaqhubeka phakathi kwe-breaker ne-AFCI;
- ubude bezintambo abukho ngaphezu kwamafidi angu-50 ocingweni lwe-gauge engu-14, namafidi angu-70 ngocingo lwegeji engu-12;futhi
- ibhokisi lokuphuma lokuqala limakwe njengeliphuma kuqala.
- isitsha se-AFCI esohlwini esifakwe endaweni yokuqala yokuphuma kusekethe sihlanganiswe nedivayisi efakwe kuhlu yokuvikela okweqile, lapho zonke lezi zimo ezilandelayo zihlangatshezwana nazo:
- i-wiring iyaqhubeka phakathi kwedivayisi nesitsha;
- ubude bezintambo abukho ngaphezu kwamafidi angu-50 ocingweni lwe-gauge engu-14 namafidi angu-70 ocingweni lwe-12-gauge;
- indawo yokuphuma yokuqala imakwe njengendawo yokuqala yokuphuma;futhi
- inhlanganisela yedivayisi yokuvikela okudlulele kanye nesitsha se-AFCI kukhonjwa njengokuhlangabezana nezimfuneko zohlobo oluhlanganisiwe lwe-AFCI.
- isitsha se-AFCI kanye nendlela yokufaka izintambo zensimbi;futhi
- isitsha se-AFCI kanye ne-concrete encasement.
Isifinyezo
Kafushane, ukuze uqinisekise ukuthi ama-circuit breaker nezimpahla zisebenza kahle, abanikazi bezindlu nabahloli bezindlu kufanele ngezikhathi ezithile bajikelezise noma bahlole izingxenye zikagesi ukuze zisebenze kahle.Isibuyekezo sakamuva se-IRC sidinga ukuvikelwa okuqondile kwe-GFCI ne-AFCI kuma-receptacles angu-15- no-20-amp.Abahloli basekhaya kufanele bazijwayeze nale mihlahlandlela emisha ukuze baqinisekise ukuhlolwa nokuhlolwa okufanele kwama-GFCI nama-AFCI.
