Ibibazo byavutse hamwe na bimwe mubisabwa muri NFPA 70®, Code National Electric Code® (NEC®), bijyanye no kurinda GFCI kubice byo guturamo.Inzira yo gusubiramo ya NEC ya 2020 yasohotse harimo kwaguka gukomeye kwibyo bisabwa, ubu bikaba bigera no kubakira kugeza kuri 250V kumuzunguruko wamashami wagereranijwe na 150V kubutaka cyangwa munsi, hamwe nubutaka bwose (bwarangiye cyangwa butarangiye) hamwe no hanze yose ahacururizwa (reseptacle cyangwa ntabwo).Ntagushidikanya ko umugenzuzi afite inshingano zikomeye zo kureba niba ibisabwa biboneka muri 210.8 bikoreshwa neza.
Birakwiye ko dusubiramo impamvu iri vugurura ryakozwe mbere.Ibisabwa na GFCI akenshi bisaba impamvu zifatika za tekiniki zo kwemeza kode ikora kode kugirango yongere ibikoresho bishya, ibikoresho, cyangwa uturere kurutonde.Mugihe cyisubiramo rya NEC 2020, impfu nyinshi ziherutse gutangwa nkimpamvu zituma dukeneye kwagura uburinzi bwa GFCI kubantu batuye.Ingero zirimo umukozi washyizwemo amashanyarazi ningufu zingirakamaro zingana;umwana watewe n'amashanyarazi mugihe yinyerera inyuma yumye ashakisha injangwe ye;n'umuhungu ukiri muto waje guhura nigice cyogukoresha ingufu za AC hamwe nuruzitiro ruhuza urunigi ubwo yacaga mu gikari cyumuturanyi ataha murugo.Ibi bintu bibabaje byashoboraga gukumirwa iyo GFCI iba igice cyo kugereranya.
Ikibazo kimaze kuvugwa mubijyanye na 250V gisabwa nuburyo gishobora kugira ingaruka kumurongo wakirwa.Ibisabwa kugirango ukingire GFCI mugikoni ntabwo bisobanutse neza nkuko biri mubikorwa bidatuye.Ubwa mbere, ibyakiriwe byashyizweho kugirango bikorere igikoni bigomba gukingirwa GFCI.Ibi ntabwo mubyukuri bikoreshwa muburyo bwakirwa, kubera ko mubisanzwe bidashyizwe muburebure bwa konte.Nubwo byaba aribyo, nubwo, urubanza rushobora gukorwa ko reseptable zihari kugirango zikore urwego kandi ntakindi.Ibindi bitondekanya ibintu muri 210.8 (A) bishobora gusaba kurinda GFCI kubirindiro byakirwa ni sink, aho urwego rwakirwa rwashyizwe muri metero 6 zumwanya wo hejuru imbere yikibindi cyarohamye.Urutonde rwakirwa ruzakenera gusa kurinda GFCI niba rwashizwe muri iyi zone ya metero 6.
Ariko, hari ahandi hantu hatuwe aho ikibazo cyoroshye cyane, nko kumesa.Nta ntera isabwa muri iyo myanya: niba reseptpcle yashyizwe mucyumba cyo kumeseramo / agace, bisaba kurinda GFCI.Kubwibyo, ibyuma byumye birasabwa kurindwa GFCI kuko biri mumyenda.Kimwe nukuri kubutaka;ku nshuro ya 2020, akanama gakora kode yakuyeho impamyabumenyi "itarangiye" mu nsi yo hasi.Igaraje ni akandi gace karimo ibintu byose, nabyo, bivuze ko gusudira, compressor zo mu kirere, nibindi bikoresho byose bikoresha amashanyarazi cyangwa ibikoresho ushobora gusanga mu igaraje bizakenera uburinzi bwa GFCI niba bihujwe n’umugozi.
Hanyuma, kwaguka kwa GFCI kwakira ibiganiro byinshi ni ukongera ibicuruzwa byo hanze.Menyako ntavuze ngo "hanze yakirwa hanze" - ibyo byari bimaze gutwikirwa.Uku kwaguka gushya kugera no mubikoresho bigoye cyane, usibye ibikoresho byo gushonga urubura hamwe n’ahantu ho gucana.Ibi bivuze ko agace ka kondereseri konderasi igomba gukingirwa GFCI, nayo.Iyo iki cyifuzo gishya kimaze gutangira gushyirwa mubikorwa bishya, byaje kugaragara ko hari ikibazo cya sisitemu zimwe na zimwe zicamo ibice zidafite ingufu zikoresha ibikoresho byo guhindura ingufu kugirango bigenzure umuvuduko wa compressor kandi bishobora gutera kwikuramo uburinzi bwa GFCI .Kubera iyo mpamvu, NEC irimo gutunganya ivugurura ry’agateganyo rya Tentative ku ya 210.8 (F) mu rwego rwo gutinza ishyirwa mu bikorwa ry’izi sisitemu zicamo ibice kugeza ku ya 1 Mutarama 2023. Ubu TIA iri mu rwego rwo gutanga ibitekerezo ku mugaragaro mbere yuko isubira kuri komite yo gusuzuma no gukora.TIA isobanura neza ko komite ikomeje gushyigikira kurinda ibyo bicuruzwa, ariko ishaka guha inganda igihe runaka kugira ngo iki kibazo gikemuke kuri ibi bice byihariye.
Hamwe nizo mpinduka zose zingenzi kubisabwa na GFCI, birashobora kwemezwa ko ukwezi kwa 2023 kwisubiramo kuzabona imirimo myinshi ikorwa hafi yibi bikoresho bikiza ubuzima.Kuguma kwihuta hamwe nikiganiro ntabwo bizafasha gusa gahunda yo kuvugurura code, bizanagira uruhare muri NEC kwakirwa mu nkiko nyinshi mugihugu.
