Abantu abeze apha banokuba nombuzo kwiintlobo ze-GFCI.Ngokusisiseko, zintathu iindidi eziphambili ze-GFCI.
Izixhobo ze-GFCI
Eyona GFCI ixhaphakileyo esetyenziswa kumakhaya okuhlala sisixhobo se-GFCI.Esi sixhobo esingabizi kakhulu sithatha indawo yesixhobo esisemgangathweni (indawo yokuphuma).Ihambelana ngokupheleleyo nayo nayiphi na i-outlet esemgangathweni, inokukhusela ezinye iindawo eziphumayo ezisezantsi (nayiphi na indawo yokuphuma ifumana amandla kwi-GFCI).Oku kuchaza utshintsho ukusuka kwi-GFI ukuya kwi-GFCI-ukubhekisela "kwiisekethe" ezikhuselweyo.
Olu hlobo lweendawo zokuthengisa ze-GFCI ngokuqhelekileyo "zityebile" kuneendawo ezisemgangathweni ngoko ke zithatha indawo enkulu kwiqela lemigulukudu enye okanye ibhokisi yombane yeqela eliphindwe kabini.Itekhnoloji entsha efana neFaith Electric GFCI ithatha indawo encinci kakhulu kunangaphambili.Ukufaka iintambo kwi-GFCI ayisiyonto inkulu, kodwa kufuneka uyenze ngokuchanekileyo ukuze ukhuseleko lusebenze ezantsi.
GFCI Circuit Breaker
Iingcali zisebenzisa i-GFCI izaphuli zesekethe rhoqo kuba zivumela abakhi kunye neengcibi zombane ukuba basebenzise iindawo zokuthengisa eziqhelekileyo kwaye bafake ngokulula isaphuli sesekethe ye-GFCI enye kwibhokisi yephaneli.I-GFCI i-circuit breakers inokukhusela yonke into ekhoyo kwiisekethe-izibane, iivenkile, abalandeli, njl.
GFCI ephathwayo
Olu hlobo lwesixhobo lubonelela ngokhuseleko lwenqanaba le-GFCI kwiyunithi ephathekayo.Ukuba unesixhobo esifuna ukhuseleko lwe-GFCI, kodwa asikwazi kuyifumana indawo ekhuselweyo—oku kukunika ukhuseleko olufanayo.
PHI UFAKWA I-GFCIS
Uninzi lwezixhobo zangaphandle kwizindlu ezakhelwe ukuthobela iKhowudi yoMbane yeSizwe (NEC) zifuna ukukhuselwa kwe-GFCI ukususela malunga no-1973. I-NEC yandisa oko ukuze kuquke izixhobo zokuhlambela ngo-1975. Ngo-1978, iindawo zokuphuma eludongeni zegaraji zongezwa.Kuthathe kude kube malunga no-1987 ukuba ikhowudi iquke izixhobo zasekhitshini.Abaninimzi abaninzi bafumanisa ukuba baphinda benza umbane wabo ukuze bathobele umthetho okhoyo.Zonke izixhobo ezikwiindawo zokurhubuluza kunye nemigangatho engaphantsi engagqitywanga nazo zifuna iindawo ze-GFCI okanye iziqhekeza (ukusukela ngo-1990).
Kucacile ukuba ii-breakers ze-GFCI ezintsha zenza ukubuyisela ikhaya ngokhuseleko lwe-GFCI kube lula kunokutshintsha indawo yokuphuma nganye kwinkqubo.Kumakhaya akhuselweyo ngeefusi (cinga nzulu ngokuphucula ibhokisi yakho ukuze uphucule ikhaya), unokufuna ukuqwalasela ukusebenzisa izixhobo ze-GFCI.Ukuphucula, sincoma ukugxila kwezona ndawo zibaluleke kakhulu njengezindlu zangasese, amakhitshi, iindawo zokukhasa, kunye neendawo zangaphandle.
