Kuvele izinkinga ngezinye zezimfuneko ezintsha ku-NFPA 70®, National Electrical Code® (NEC®), ezihlobene nokuvikelwa kwe-GFCI kwezindawo zokuhlala.Umjikelezo wokubukeza wohlelo lwango-2020 lwe-NEC uhlanganise ukunwetshwa okubalulekile kwalezi zidingo, manje ezinwebeka ukuze zifake izinto zokungenisa izinto ezifika ku-250V kumasekethe egatsha alinganiselwe ngo-150V ukuya phansi noma ngaphansi, kanye nawo wonke amagumbi angaphansi (aqediwe noma cha) nawo wonke angaphandle. izitolo (isitsha noma cha).Akungabazeki ukuthi umhloli unesibopho esikhulu kakhulu sokuqinisekisa ukuthi izidingo ezitholakala ku-210.8 zisetshenziswa ngendlela efanele.
Kuyafaneleka ukubuyekeza ukuthi kungani lezi zibuyekezo zenziwe kwasekuqaleni.Izimfuneko ze-GFCI zivame ukudinga izizathu ezinkulu zobuchwepheshe ukukholisa iphaneli yokwenza amakhodi ukuthi ingeze amadivayisi amasha, okokusebenza, noma izindawo kuhlu.Ngesikhathi somjikelezo wokubuyekeza we-NEC yango-2020, ukushona okuningi kwakamuva kwethulwe njengezizathu zokuthi kungani sidinga ukwandisa ukuvikelwa kwe-GFCI kubantu abahlala ezindaweni zokuhlala.Izibonelo zihlanganisa isisebenzi esashokhwa ugesi uhlaka olunamandla lwebanga elingasebenzi kahle;ingane eyabanjwa ugesi ngesikhathi ikhasa ngemva komshini wokomisa ibheka ikati layo;kanye nomfana osemncane owahlangana kanye kanye neyunithi yokujiya i-AC enamandla kanye nothango olucijile lapho enqamula igceke likamakhelwane esendleleni eya ekhaya ezodla isidlo sakusihlwa.Lezi zehlakalo ezibuhlungu bezingavinjelwa ukuba i-GFCI ibiyingxenye yezibalo.
Umbuzo osuvele uphakanyiswe mayelana nemfuneko ye-250V ukuthi ingathinta kanjani i-receptace yobubanzi.Izidingo zokuvikela i-GFCI ekhishini azicacisiwe njengoba zinjalo ezindaweni okungezona ezokuhlala.Okokuqala, izitsha ezifakwe ukuze kusetshenziswe izindawo zokubala zasekhishini kufanele zivikelwe i-GFCI.Lokhu akusebenzi ngempela ezitsheni zobubanzi, njengoba lezo ngokuvamile azifakwa kubude be-countertop.Noma ngabe bekhona, noma kunjalo, icala lingenziwa ukuthi izitsha zikhona ukuze zinikeze uhla futhi akukho okunye.Ezinye izinto zohlu ku-210.8(A) ezingase zidinge ukuvikelwa kwe-GFCI yezimpahla zobubanzi amasinki, lapho i-receptacle yobubanzi ifakwe phakathi kwamafithi angu-6 phezulu ngaphakathi konqenqema lwesitsha sikasinki.I-receptacle yobubanzi izodinga kuphela ukuvikelwa kwe-GFCI uma ifakwe ngaphakathi kwale zoni eyi-6-foot.
Kodwa-ke, zikhona ezinye izindawo endaweni yokuhlala lapho udaba luqondile, njengendawo yokuwasha.Awekho amabanga anemibandela kulezo zikhala: uma isitsha sempahla sifakwe egumbini lokuwashela/indawo, sidinga ukuvikelwa kwe-GFCI.Ngakho-ke, izingubo zokomisa izingubo manje sezidingeka ukuthi zivikeleke nge-GFCI ngoba zisendaweni yokuwasha.Okufanayo kuyiqiniso nasezindlini ezingaphansi;ngohlelo lwango-2020, iphaneli elenza amakhodi lisuse iziqu “ezingakaqediwe” ezindlini ezingaphansi.Igalaji ingenye indawo ehlanganisa konke, futhi, okusho ukuthi amashisela, ama-compressor emoyeni, nanoma yiliphi elinye ithuluzi elisebenza ngogesi noma into esetshenziswayo ongayithola egaraji izodinga ukuvikelwa kwe-GFCI uma ixhunywe intambo nepulaki.
Okokugcina, ukunwetshwa kwe-GFCI okuthola ingxoxo eningi ukwengezwa kwezitolo zangaphandle.Qaphela ukuthi angishongo ukuthi “izimpahla zangaphandle”—lezo zase zimboziwe.Lokhu kunwetshwa okusha kudlulela nakumishini enezintambo eziqinile, ngaphandle kwemishini yokuncibilika kweqhwa nezindawo zokukhanyisa.Lokhu kusho ukuthi iyunithi ye-condenser ye-air conditioner idinga ukuvikelwa kwe-GFCI, nayo.Lapho le mfuneko entsha isiqala ukuqaliswa ekufakweni okusha, kwasheshe kwacaca ukuthi kunenkinga ngezinhlelo ezithile ze-mini-split ductless ezisebenzisa amathuluzi okuguqula amandla ukulawula isivinini se-compressor futhi angabangela ukukhubeka okungahleliwe kokuvikelwa kwe-GFCI. .Ngenxa yalokhu, i-NEC icubungula i-Tentative Interim Amendment ku-210.8(F) ukuze ibambezeleke ukuqaliswa kwalezi zinhlelo zokuhlukaniswa okuncane kuze kube nguJanuwari 1, 2023. Le TIA okwamanje isesigabeni sokuphawula komphakathi ngaphambi kokuba ibuyele emuva ikomidi lokudingida nokwenza.I-TIA ikwenza kucace ukuthi ikomidi lisakweseka ukuvikelwa kwalezi zikhungo, kodwa limane lifuna ukunikeza imboni isikhathi esithile ukuze yenze isixazululo salolu daba lwalezi zikhungo.
Ngazo zonke lezi zinguquko ezibalulekile ezidingweni ze-GFCI, kungacishe kuqinisekiswe ukuthi umjikelezo wokubuyekeza wango-2023 uzobona umsebenzi omningi owenziwe mayelana nalawa madivayisi asindisa ukuphila.Ukuhlala unolwazi ngengxoxo ngeke kusize nje kuphela uhlelo lokubuyekezwa kwamakhodi, kuzophinde kube nomthelela ekutheni i-NEC yamukelwe ezindaweni eziningi ezweni lonke.
