Ikhodi Kagesi Kazwelonke (NEC) nawo wonke amakhodi okwakha endawo adinga ukuvikelwa kwesiphazamisi sesifunda esinephutha eliphansi ezitsheni eziningi zokuphuma kuzo zonke izindawo ezingaphakathi nangaphandle.Izidingo zikhona ukuze kuvikelwe abasebenzisi ekwethukeni uma kwenzeka kuba nephutha lomhlabathi, isimo lapho amandla kagesi ageleza ngephutha ngaphandle kwesekethe emisiwe.
Lesi sivikelo esidingekayo singanikezwa i-circuit breaker noma izitsha ze-GFCI.Izinzuzo kanye nobubi bendlela ngayinye kuncike ekufakweni.Futhi, sicela uqaphele ukuthi ikhodi yendawo kagesi—imithetho okufanele uyilandele ukuze uphumelele ukuhlolwa kukagesi—ingase ibe nezidingo eziqondile zokuhlinzeka ngokuvikela kwe-GFCI endaweni yakho.
Ngokuyisisekelo, kokubili i-circuit breaker kanye ne-GFCI receptacle benza into efanayo, ngakho-ke ukwenza ukukhetha okufanele kudinga ukuthi ukale izinzuzo nezinkinga ezihlukahlukene zalokhu ngakunye.
Iyini I-GFCI Receptacle?
Ungahlulela ukuthi i-receptacle iyi-GFCI noma cha ngokubukeka kwayo kwangaphandle.I-GFCI ihlanganiswe ne-outlet kagesi futhi iklanywe ngenkinobho yokusetha kabusha ebomvu (noma okungenzeka ibe mhlophe) ku-faceplate ye-outlet.Isitolo siqapha ukuthi mangakanani amandla angena kuso uma sisetshenziswa.Uma noma yiluphi uhlobo lokugcwala kukagesi noma ukungalingani kutholwa isitsha, siklanyelwe ukugibelisa isekethe ngengxenye yesekhondi.
Izimpahla ze-GFCI ngokuvamile zisetshenziselwa ukumiselela isitsha esivamile ukuze kunikeze ukuvikeleka endaweni eyodwa yokuphuma.Kodwa-ke, izinsiza ze-GFCI zingafakwa izintambo ngezindlela ezimbili ezihlukene ngaleyo ndlela zinikeze amazinga amabili ahlukene okuvikela.Ukuvikelwa kwezintambo kwendawo eyodwa kunikeza ukuvikeleka kwe-GFCI endaweni eyodwa kuphela.Izintambo ezinezindawo eziningi zivikela isitsha sokuqala se-GFCI kanye nazo zonke izinto ezisetshenziswayo ezansi nomfula kumjikelezo ofanayo.Kodwa-ke, ayivikeli ingxenye yesekethe ephakathi kwayo kanye nephaneli yesevisi enkulu.Isibonelo, uma isitsha se-GFCI esinezintambo zokuvikela izindawo eziningi siyinto yesine kuyisekethe ehlanganisa izindawo zokuphuma eziyisikhombisa ngokuphelele, kulesi simo izindawo ezintathu zokuqala ngeke zivikelwe.
Ukusetha kabusha i-receptacle kulula kakhulu kunokuya yonke indlela uye kuphaneli yesevisi ukuze usethe kabusha isinqamuli, kodwa khumbula ukuthi uma ufaka isekethe ukuze uthole ukuvikelwa kwezindawo eziningi kusuka esakhiweni esisodwa se-GFCI, leyo mpahla ilawula yonke into ezansi nomfula.Kuzodingeka uhlehle ukuze uthole i-GFCI ye-receptacle ukuze uyisethe kabusha uma kunenkinga yezintambo ezansi nomfula.
Iyini i-GFCI Circuit Breaker?
Ama-circuit breaker e-GFCI avikela yonke isekethe.I-GFCI circuit breaker ilula: ngokufaka eyodwa kuphaneli yesevisi (ibhokisi le-breaker), yengeza ukuvikelwa kwe-GFCI kumjikelezo wonke, okuhlanganisa izintambo kanye nawo wonke amadivayisi nezinto ezisetshenziswayo ezixhunywe kusekethe.Ezimeni lapho ukuvikelwa kwe-AFCI (i-arc-fault circuit interrupter) kuphinde kubizelwe (isimo esivame ukuvama), kukhona imisebenzi emibili ye-GFCI/AFCI ama-circuit breaker angasetshenziswa.
Izinqamuli zesekhethi ze-GFCI zinengqondo ezimeni lapho zonke izitolo eziseseketheni zidinga ukuvikelwa.Isibonelo, ake sithi wengeza isifunda sesitsha seshabhu yasegaraji noma indawo enkulu yevulandi yangaphandle.Ngenxa yokuthi zonke lezi zisetshenziswa zidinga ukuvikelwa kwe-GFCI, kungenzeka ukuthi kusebenza kahle kakhulu ukuhlanganisa isekethe nge-breaker ye-GFCI ukuze yonke into esesekethe ivikelwe.Iziphuli ze-GFCI zingathwala izindleko eziphezulu, noma kunjalo, ngakho ukwenza lokhu akuhlali kuwukukhetha ukonga kakhulu.Okunye, ungase ufake i-GFCI ephumayo endaweni yokuqala kusekethe ukuze unikeze ukuvikelwa okufanayo ngezindleko eziphansi.
Ungakhetha Nini I-GFCI Receptacle Ngaphezulu Kwe-GFCI Circuit Breaker
Kufanele uye kuphaneli yesevisi ukuze uyisethe kabusha lapho i-GFCI breaker ihamba.Uma i-GFCI ithatha uhambo, kufanele ukwazi ukuyisetha kabusha endaweni yesitsha.IKhodi Kagesi Kazwelonke (NEC) idinga ukuthi izitsha ze-GFCI kufanele zibe ezindaweni ezifinyeleleka kalula, iqinisekise ukuthi kukhona ukufinyelela okulula kokusetha kabusha isitsha uma sihamba.Ngakho-ke, izitsha ze-GFCI azivunyelwe ngemuva kwefenisha noma izinto zikagesi.Uma uzoba nezimpahla ezidinga ukuvikelwa kwe-GFCI kulezi zindawo, sebenzisa i-GFCI breaker.
Ngokuvamile, izinsiza ze-GFCI kulula ukuzifaka.Ngezinye izikhathi isinqumo sifika embuzweni wokusebenza kahle.Isibonelo, uma udinga ukuvikelwa kwe-GFCI kwesitsha esisodwa noma ezimbili kuphela—ake sithi, ngegumbi lokugezela noma elondolo—mhlawumbe kwenza umqondo omkhulu ukumane ufake i-GFCI yokufaka kulezi zindawo.Futhi, uma uyi-DIYer futhi ungajwayelene nokusebenza kuphaneli yesevisi, ukufaka esikhundleni sendawo yokwamukela izinto kuyindlela elula nephephile kunokushintsha i-circuit breaker.
Izimpahla ze-GFCI zinemizimba emikhulu kakhulu kunezimpahla ezijwayelekile, ngakho-ke ngezinye izikhathi isikhala esingaphakathi kwebhokisi lodonga singathinta ukukhetha kwakho.Ngamabhokisi anosayizi ojwayelekile, kungase kungabi khona indawo eyanele yokwengeza isitsha se-GFCI ngokuphephile, kulokhu ukwenza i-GFCI breaker kungaba inketho engcono.
Izindleko nazo zingaba yisici esinqumweni.Isitsha se-GFCI ngokuvamile sibiza cishe u-$15.I-GFCI breaker ingase ikubize u-$40 noma u-$50, uma iqhathaniswa no-$4 kuya ku-$6 ngesephuli esijwayelekile.Uma imali iyinkinga futhi udinga kuphela ukuvikela indawo eyodwa, isitolo se-GFCI singase sibe yisinqumo esingcono kunesephula i-GFCI.
Okokugcina, kunekhodi yendawo kagesi, engase ibe nezidingo ezithile ze-GFCI ezihlukile kulezo eziphakanyiswe yi-NEC.
