Ngokuvamile ikhishi lisebenzisa ugesi omningi kunanoma yimaphi amanye amagumbi ekhaya, futhi I-NEC(Ikhodi Kagesi Kazwelonke) ibeka ukuthi amakhishi kufanele aphakelwe kakhulu ngamasekethe amaningi.Ekhishini elisebenzisa izinto zikagesi zokupheka, lokhu kusho ukuthi lidinga amasekhethi ayisikhombisa noma ngaphezulu.Qhathanisa lokhu nezimfuneko zekamelo lokulala noma enye indawo yokuhlala, lapho isekethe yokukhanyisa yenhloso evamile ingasebenza kuzo zonke izibani nezindawo zokuxhuma.
Imishini eminingi yasekhishini yayixhunywe ezitsheni ezijwayelekile zokuphuma phambili, kodwa njengoba izinto zasekhishini sezikhulile futhi zikhudlwana ngokuhamba kweminyaka, manje sekujwayelekile - futhi kudingwa ngekhodi yokwakha - ngayinye yalezi zisetshenziswa ukuba ibe nesekethe kagesi ezinikele engasebenzisi lutho olunye. .Ngaphandle kwalokho, amakhishi adinga amasekethe amancane kagesi kanye nesekethe eyodwa yokukhanyisa okungenani.
Sicela uqaphele ukuthi akuwona wonke amakhodi okwakha endawo anezidingo ezifanayo.Nakuba i-NEC (Ikhodi Kagesi Kazwelonke) isebenza njengesisekelo samakhodi amaningi endawo, imiphakathi ngayinye ingakwazi, futhi ivame ukwenza, ukuzibekela izindinganiso ngokwazo.Njalo hlola neziphathimandla zendawo yakho mayelana nezimfuneko zomphakathi wakho.
01. Isekethe yesiqandisi
Ngokuyisisekelo, isiqandisi sesimanje sidinga umjikelezo ozinikele we-20-amp.Ungase ube nesiqandisi esincane esixhunywe kwisekethe yokukhanyisa evamile okwamanje, kodwa ngesikhathi sanoma yikuphi ukulungiswa kabusha okukhulu, faka isekethe ezinikele (120/125-volts) yesiqandisi.Kule sekethi engu-20-amp enikelwe, kuzodingeka intambo engu-12/2 non-metallic (NM) ene-ground sheathed ukuze kufakwe izintambo.
Lo mjikelezo ngokuvamile awudingi ukuvikelwa kwe-GFCI ngaphandle uma indawo yokuphuma ingaphakathi kwamafidi angu-6 kusinki noma itholakala egalaji noma engaphansi, kodwa ngokuvamile idinga ukuvikelwa kwe-AFCI.
02. Range Circuit
Ibanga likagesi ngokuvamile lidinga isifunda esizinikele esingu-240/250-volt, 50-amp.Lokho kusho ukuthi uzodinga ukufaka intambo engu-6/3 NM (noma intambo engu-#6 THHN epayipini) ukuze uphakele ububanzi.Kodwa-ke, izodinga kuphela i-receptacle engu-120/125-volt ukuze inike amandla izilawuli zebanga nehood yokukhipha umoya uma kuyibanga legesi.
Ngesikhathi sokulungiswa kabusha okukhulu, noma kunjalo, kuwumcabango omuhle ukufaka isekethe yebanga likagesi, noma ngabe ngeke uyisebenzise njengamanje.Ngokuzayo, ungase ufune ukuguqulela ebangeni likagesi, futhi ukuba nalesi sikethi sitholakale kuzoba indawo yokuthengisa uma uke wathengisa indlu yakho.Sicela ukhumbule ukuthi ibanga likagesi lidinga ukusunduzelwa emuva odongeni, ngakho beka indawo yokuphuma ngokufanele.
Nakuba ama-circuits angu-50-amp ajwayelekile kububanzi, amanye amayunithi angase adinge amasekhethi afinyelela ku-60 amps, kuyilapho amayunithi amancane angase adinge ama-circuits amancane-40-amps noma 30-amps.Kodwa-ke, ukwakhiwa kwendlu entsha kuvame ukufaka amasekhethi ebanga lama-amp angu-50, njengoba lawa anele iningi lezindawo zokupheka zokuhlala.
Uma itop yokupheka ne-ovini yodonga kuyiyunithi ehlukene emakhishini, Ikhodi Kagesi Kazwelonke ngokuvamile ivumela womabili amayunithi ukuthi anikwe amandla yisekhethi efanayo, inqobo nje uma umthwalo kagesi ohlanganisiwe ungeqi umthamo ophephile waleyo sekethi.Kodwa-ke, ngokuvamile ukusetshenziswa kwamasekhethi angu-2-, 30-, noma angu-40- amp asetshenziswa kusukela kuphaneli eyinhloko ukuze anike amandla ngayinye ngokwehlukana.
03. Umshini wokuwasha izitsha
Lapho ufaka umshini wokuwasha izitsha, isifunda kufanele sibe yisifunda esizinikezele esingu-120/125-volt, 15-amp.Le sekethi engu-15-amp inikezwa ngocingo lwe-14/2 NM olunomhlabathi.Ungase futhi ukhethe ukuphakela umshini wokuwasha izitsha ngesekethe engu-20-amp usebenzisa intambo engu-12/2 NM enomhlaba.Sicela uqinisekise ukuvumela ukuntenga okwanele kwekhebuli ye-NM ukuze umshini wokugeza izitsha ukhishwe futhi useviswe ngaphandle kokuwunqamula—umlungisi wakho womshini uzokubonga.
Qaphela: abawashi bezitsha bazodinga indlela yokunqanyulwa kwendawo noma ukuvala amaphaneli.Le mfuneko ifinyelelwa ngokucushwa kwentambo nepulaki noma idivayisi encane yokukhiya efakwe ku-breaker kuphaneli ukuvimbela ukushaqeka.
Abanye ochwepheshe bakagesi bazofaka izintambo ekhishini ukuze umshini wokuwasha izitsha nokulahlwa kukadoti kunikwe amandla yisekethe efanayo, kodwa uma lokhu kwenziwa, kufanele kube isekethe engama-amp angu-20 futhi kufanele kuqikelelwe ukuthi ukulinganisa okuphelele kwazo zombili izinto zikagesi akudluli. Amaphesenti angama-80 wesilinganiso se-circuit amperage.Udinga ukuhlola neziphathimandla zekhodi yendawo ukuze ubone ukuthi lokhu kuvunyelwe yini.
Izimfuneko ze-GFCI kanye ne-AFCI ziyahlukahluka endaweni ethile kuye endaweni ethile.Ngokuvamile, isifunda sidinga ukuvikelwa kwe-GFCI, kodwa uma ukuvikelwa kwe-AFCI kudingekile noma cha kuzoncika ekutolikweni kwendawo yekhodi.
04. Isekhethi yokulahlwa kukadoti
Ukulahlwa kukadoti kwenza umsebenzi wokuhlanza ukungcola ngemva kokudla.Lapho zigcwele udoti, zisebenzisa ingcosana ye-amperage njengoba zigaya udoti.Ukulahlwa kukadoti kudinga isekethe ezinikele engu-15-amp, ephakelwa ikhebula elingu-14/2 NM elinomhlabathi.Ungase futhi ukhethe ukuphakela isilahlisi ngesekhethi engu-20-amp, usebenzisa intambo engu-12/2 NM enomhlaba.Lokhu kuvame ukwenziwa lapho ikhodi yendawo ivumela ukulahlwa ukwabelana ngesekethe nomshini wokuwasha izitsha.Kufanele ngaso sonke isikhathi uhlole nomhloli wendawo yangakini ukuze ubone ukuthi lokhu kuvunyelwe yini endaweni yangakini.
Izindawo ezihlukene zingase zibe nezidingo ezihlukene ezidinga ukuvikelwa kwe-GFCI ne-AFCI yokulahlwa kukadoti, ngakho-ke sicela uthintane neziphathimandla zendawo yakho ngalokhu.Kubandakanya kokubili ukuvikela kwe-AFCI kanye ne-GFCI kuyindlela ephephe kunazo zonke, kodwa ngenxa yokuthi ama-GFCI angathambekela “ekuhambeni ngendlela exakile” ngenxa yokuqhuma kwezimoto, ochwepheshe bezogesi abaqeqeshiwe bavamise ukushiya ama-GFCI kulawa masekhethi lapho amakhodi endawo akuvumela khona.Ukuvikelwa kwe-AFCI kuzodingeka njengoba la masekethi asetshenziswa iswishi yodonga futhi ukulahlwa kungase kufakwe intambo ukuze kuxhunywe endaweni ephuma odongeni.
05. Isekethe ye-Oven ye-Microwave
Ihhavini ye-microwave idinga i-20-amp ezinikele, isekethe engu-120/125-volt ukuyiphakela.Lokhu kuzodinga intambo engu-12/2 NM enenhlabathi.Amahhavini ama-microwave afika ngezinhlobo nosayizi abahlukene, lokho kusho ukuthi amanye amamodeli e-countertop kuyilapho amanye ama-microwave ephakama ngaphezu kwesitofu.
Nakuba kuvamile ukubona ohhavini bemicrowave bexhunywe ezitolo ezijwayelekile, amahhavini ama-microwave amakhulu angadonsa ama-watts angaba ngu-1500 ngaleyo ndlela adinga amasekhethi awo azinikele.
Le sekethi ayidingi ukuvikelwa kwe-GFCI ezindaweni eziningi, kodwa kwesinye isikhathi iyadingeka lapho into esetshenziswayo ixhuma endaweni efinyeleleka kalula.Ukuvikelwa kwe-AFCI kuvame ukudingeka kule sekhethi njengoba into esetshenziswayo ixhunywe ku-outlet.Kodwa-ke, ama-microwaves anesandla emithwalweni ye-phantom, ngakho-ke ungacabanga ukuwakhipha lapho engasetshenziswa.
06. Lighting Circuit
Impela, ikhishi belingeke liphelele ngaphandle kwesekethe yokukhanyisa ukuze kukhanye indawo yokupheka.Isekethe eyodwa ezinikele engu-15-amp, 120/125-volt iyadingeka okungenani ukunika amandla izibani zasekhishini, njengezinto ezifakwa ophahleni, amalambu e-canister, amalambu angaphansi kwekhabhinethi, namalambu emigqa.
Isethi ngayinye yezibani kufanele ibe neswishi yayo ukuze ukwazi ukulawula ukukhanya.Ungase ufune ukwengeza ifeni yophahla noma mhlawumbe ibhange lamalambu ethrekhi esikhathini esizayo.Ngalesi sizathu, kuwumqondo omuhle ukufaka isekethe engu-20-amp ukuze kusetshenziswe ukukhanya okujwayelekile, noma ikhodi idinga kuphela isekethe engu-15-amp.
Ezindaweni eziningi, isekethe enikezela ngezinto zokukhanyisa kuphela ayidingi ukuvikelwa kwe-GFCI, kodwa ingadingeka uma iswishi yodonga itholakala eduze kukasinki.Ukuvikelwa kwe-AFCI ngokuvamile kuyadingeka kuwo wonke amasekhethi okukhanyisa.
07. Iziyingi Zokusebenza Ezincane
Uzodinga amasekhethi amabili azinikele angu-20-amp, 120/125-volt phezu kwekhawunta yakho ukuze uqalise imithwalo yakho encane kagesi, okuhlanganisa namadivaysi afana namathosta, amagridi kagesi, amabhodwe ekhofi, izixube, njll. Amasekhethi amabili adingeka okungenani ngekhodi ;ungafaka futhi okuningi uma izidingo zakho zidinga.
Sicela uzame ukucabanga ukuthi uzozibeka kuphi izinto zikagesi phezu kwekhawunta yakho uma uhlela amasekhethi kanye nendawo yezitolo.Uma ungabaza, engeza amasekhethi engeziwe wesikhathi esizayo.
Iziyingi ezinikeza amandla i-plug-in ezifaka izinto zikagesi ze-countertop kufanelenjaloube nakho kokubili ukuvikelwa kwe-GFCI ne-AFCI ukuze kucatshangelwe ukuphepha.
