IKhowudi yoMbane yeSizwe (NEC) kunye nazo zonke iikhowudi zokwakha zasekhaya zifuna ukukhuselwa kokuphazamiseka kwesekethe ephantsi kwezixhobo ezininzi zokukhupha kuyo yonke indawo yangaphakathi nangaphandle.Iimfuno zikhona zokukhusela abasebenzisi kumothuko xa kukho isiphene somhlaba, imeko apho umsinga wombane uhamba ngempazamo ngaphandle kwesekethe esekiweyo.
Olu khuseleko lufunekayo lunokubonelelwa nokuba yi-breaker circuit okanye i-GFCI receptaces.Iinzuzo kunye nokungalunganga kwendlela nganye kuxhomekeke kufakelo.Kwakhona, nceda uqaphele ukuba ikhowudi yombane yendawo-imithetho omele uyilandele ukuze uphumelele ukuhlolwa kombane-inokuba neemfuneko ezithile zendlela yokubonelela ngokhuseleko lwe-GFCI kwindawo yakho.
Ngokusisiseko, zombini isaphuli sesekethe kunye nesixhobo se-GFCI zenza into enye, ke ukwenza ukhetho oluchanekileyo kufuna ukuba ulinganise iingenelo kunye nokungalunganga ngakunye.
Yintoni iSakhelo se-GFCI?
Ungagweba ukuba i-receptacle yi-GFCI okanye hayi ngenkangeleko yayo yangaphandle.I-GFCI idityaniswe kwindawo yokukhupha umbane kwaye iyilwe ngeqhosha elibomvu (okanye elinokuba mhlophe) lokuseta ngokutsha kwiplate yobuso bendawo yokuphuma.Indawo ephuma kuyo ijonga ukuba angakanani amandla angena kuyo xa isetyenziswa.Ukuba naluphi na uhlobo lokugcwala kombane okanye ukungalingani kufunyenwe kwisixhobo, yenzelwe ukujikeleza isekethe kwiqhezu lomzuzwana.
Izikhongozelo ze-GFCI ziqhele ukusetyenziselwa ukuvala indawo yesixhobo sokukhupha esisemgangathweni ukunika ukhuseleko kwindawo enye.Nangona kunjalo, izixhobo ze-GFCI zinokutsalwa ngeendlela ezimbini ezahlukeneyo ngoko ke zibonelela ngamanqanaba amabini ahlukeneyo okhuseleko.Ukhuseleko lweengcingo lwendawo enye lubonelela ngokhuseleko lwe-GFCI kwisixhobo esinye kuphela.Iingcingo ezineendawo ezininzi zikhusela indawo yokuqala ye-GFCI kunye nayo yonke into yokwamkela ezantsi kwayo kwisekethe enye.Nangona kunjalo, ayikhuseli inxalenye yesekethe elele phakathi kwayo kunye nepaneli yenkonzo ephambili.Umzekelo, ukuba isakhelo se-GFCI esinentambo zokhuseleko lwendawo ezininzi sisixhobo sesine kwisekethe equka iindawo zokukhutshwa ezisixhenxe ziphelele, kule meko iindawo ezintathu zokuqala aziyi kukhuselwa.
Ukuseta kwakhona i-receptacle kulula ngakumbi kunokuhamba yonke indlela ukuya kwipaneli yenkonzo ukuseta kwakhona i-breaker, kodwa gcina engqondweni ukuba uqhagamshela isekethe yokhuseleko lwendawo ezininzi ukusuka kwi-GFCI enye yokwamkela, eso sixhobo silawula yonke into ezantsi.Kuya kufuneka ubuye umva ukuze ufumane i-GFCI yokwamkela ukuseta kwakhona ukuba kukho nawuphi na umba wocingo ongezantsi.
Yintoni i-GFCI Circuit Breaker?
Abaphuli beesekethe ze-GFCI bakhusela isekethe yonke.I-GFCI i-breaker circuit ilula: ngokufaka enye kwipaneli yenkonzo (ibhokisi ye-breaker), yongeza ukukhuselwa kwe-GFCI kwisiphaluka sonke, kubandakanywa i-wiring kunye nazo zonke izixhobo kunye nezixhobo ezixhunyiwe kwisiphaluka.Kwiimeko apho ukhuseleko lwe-AFCI (i-arc-fault circuit interrupter) lukwabizwa ngokuba (imeko eya ixhaphakileyo), kukho imisebenzi emibini ye-GFCI/AFCI izaphuli zesekethe ezinokusetyenziswa.
Izaphuli zesekethe ze-GFCI zenza ingqiqo kwiimeko apho zonke iivenkile ezikwisekethe zifuna ukukhuselwa.Umzekelo, masithi wongeza isekethe yokufumana indawo yokusebenzela yasegaraji okanye indawo enkulu yepatio yangaphandle.Ngenxa yokuba zonke ezi zixhobo zifuna ukukhuselwa kwe-GFCI, mhlawumbi kusebenza ngakumbi ukufaka ucingo kwisekethe nge-breaker ye-GFCI ukuze yonke into ekwisekethe ikhuselwe.Izaphuli ze-GFCI zinokuthwala iindleko eziphezulu, nangona kunjalo, ukwenza oku akusoloko kulukhetho loqoqosho ngakumbi.Ngenye indlela, ungafaka i-GFCI yokuphuma kwindawo yokuqala kwisekethe ukunika ukhuseleko olufanayo ngexabiso eliphantsi.
Unokukhetha nini i-GFCI ye-Receptacle ngaphezu kwe-GFCI Circuit Breaker
Kuya kufuneka uye kwiphaneli yenkonzo ukuseta ngokutsha xa i-GFCI breaker ihamba.Xa isitya se-GFCI sihamba, kufuneka ukwazi ukuseta kwakhona kwindawo yokwamkela.IKhowudi yoMbane yeSizwe (i-NEC) ifuna ukuba izikhongozeli ze-GFCI zibe kwindawo ezifikeleleka lula, ziqinisekise ukuba kukho ufikelelo olulula lokuseta kwakhona isixhobo ukuba siyahamba.Ke ngoko, izixhobo ze-GFCI azivumelekanga ngasemva kwefanitshala okanye izixhobo zombane.Ukuba uya kuba nezixhobo ezifuna ukhuseleko lwe-GFCI kwezi ndawo, sebenzisa i-GFCI breaker.
Ngokubanzi, izixhobo ze-GFCI kulula ukuzifaka.Ngamanye amaxesha isigqibo siyehla kumbuzo wokusebenza kakuhle.Umzekelo, ukuba ufuna ukukhuselwa kwe-GFCI kwindawo enye okanye ezimbini-uthi, kwigumbi lokuhlambela okanye igumbi lokuhlambela-mhlawumbi yenza eyona ngqiqo ukufaka i-GFCI kwimibhobho kwezi ndawo.Kwakhona, ukuba uyi-DIYer kwaye awuqhelananga nokusebenza kwipaneli yenkonzo, ukubuyisela isitya yindlela elula nekhuselekileyo kunokutshintsha i-breaker circuit.
Izixhobo ze-GFCI zinemizimba emikhulu kakhulu kunezixhobo eziqhelekileyo, ngoko ngamanye amaxesha indawo ebonakalayo ngaphakathi kwebhokisi yodonga inokuchaphazela ukhetho lwakho.Ngeebhokisi zobungakanani obuqhelekileyo, akunakubakho gumbi laneleyo lokongeza i-GFCI ngokukhuselekileyo, kulo mzekelo ukwenza isaphuli sesekethe ye-GFCI inokuba lolona khetho lungcono.
Iindleko nazo zinokuba ngumbango kwisigqibo.Isixhobo se-GFCI sihlala sixabisa malunga ne-15 yeedola.I-GFCI breaker ingakubiza i-$ 40 okanye i-$ 50, ngokuchasene ne-$ 4 ukuya kwi-$ 6 ye-breaker standard.Ukuba imali ingumba kwaye kufuneka ukhusele indawo enye kuphela, indawo yokuphuma ye-GFCI inokuba lukhetho olungcono kunesaphuli se-GFCI.
Okokugqibela, kukho ikhowudi yombane yasekhaya, enokuba neemfuno ezithile ze-GFCI ezahlukileyo kwezo zicetyiswe yi-NEC.
