Ngokwesiqhelo ikhitshi lisebenzisa umbane omninzi kunawo nawaphi na amanye amagumbi asekhaya, kwaye i-NEC(iKhowudi yoMbane yeSizwe) imisela ukuba amakhitshi kufuneka abonelelwe ngokwaneleyo ziisekethe ezininzi.Kwikhitshi elisebenzisa izixhobo zokupheka zombane, oku kuthetha ukuba lifuna iisekethe ezininzi ezisixhenxe nangaphezulu.Thelekisa oku kwiimfuno zegumbi lokulala okanye enye indawo yokuhlala, apho isekethe yokukhanyisa yenjongo eyodwa jikelele inokusebenza zonke izibane kunye neeplagi zokuphuma.
Uninzi lwezixhobo zasekhitshini zaziplagiwe kwizixhobo eziqhelekileyo zesiqhelo ngaphambili, kodwa njengoko izixhobo zasekhitshini ziye zaba nkulu kwaye zinkulu ngokuhamba kweminyaka, ngoku zisemgangathweni-kwaye zifunwa yikhowudi yokwakha-kwisixhobo ngasinye kwezi zixhobo ukuba sibe nesekethe yesixhobo esinikezelweyo esingasebenzisi nto yimbi. .Ngaphandle koko, iikhitshi zifuna iisekethe ezincinci zesixhobo kunye nobuncinci isekethe yokukhanya enye.
Nceda uqaphele ukuba ayizizo zonke iikhowudi zokwakha zasekuhlaleni ezineemfuno ezifanayo.Ngelixa i-NEC (iKhowudi yoMbane yeSizwe) isebenza njengesiseko kwiikhowudi ezininzi zendawo, uluntu ngabanye lunakho, kwaye luhlala lukwenza, ukumisela imigangatho ngokwabo.Soloko ujonga kwabasemagunyeni ikhowudi yendawo yakho kwiimfuno kuluntu lwakho.
01. Isekethe yefriji
Ngokusisiseko, ifriji yanamhlanje ifuna isekethe ye-20-amp ezinikeleyo.Unokuba nefriji encinci efakwe kwisekethe yokukhanyisa ngokubanzi okwangoku, kodwa ngexesha lakuphi na ukulungiswa okukhulu, faka isiphaluka esizinikezele (120/125-volts) kwifriji.Kule sekethe ye-20-amp ezinikeleyo, i-12/2 ye-non-metallic (NM) yocingo olukhuselweyo olunomhlaba luya kufuneka kwi-wiring.
Le sekethi ayifuni ukhuseleko lwe-GFCI ngaphandle kokuba indawo yokuphuma ingaphakathi kweenyawo ezi-6 kwisinki okanye ibekwe kwigaraji okanye kwindawo engaphantsi, kodwa ifuna ukhuseleko lwe-AFCI.
02. Uluhlu lweSekethe
Uluhlu lombane lufuna ngokubanzi i-240/250-volt, i-50-amp circuit.Oko kuthetha ukuba kuya kufuneka ufake intambo ye-6/3 ye-NM (okanye #6 THHN ucingo kumjelo) ukondla uluhlu.Nangona kunjalo, iya kufuna kuphela isixhobo se-120/125-volt ukunika amandla uluhlu lolawulo kunye ne-vent hood ukuba luhlobo lwegesi.
Ngexesha lohlengahlengiso olukhulu, nangona kunjalo, yingcinga entle yokufaka isekethe yoluhlu lombane, nokuba awuzukuyisebenzisa okwangoku.Kwixesha elizayo, unokufuna ukuguqulela kuluhlu lombane, kwaye ukuba nale sekethi ikhoyo iya kuba yindawo yokuthengisa ukuba ukhe wathengisa indlu yakho.Nceda ukhumbule ukuba uluhlu lombane lufuna ukutyhala umva eludongeni, ngoko ke beka indawo yokuphuma ngokufanelekileyo.
Ngelixa iisekethe ezingama-50-amp ziqhelekile kuluhlu, ezinye iiyunithi zinokufuna iisekethe ukuya kuthi ga kwi-60 amps, ngelixa iiyunithi ezincinci zinokufuna iisekethe ezincinci-40-amps okanye i-30-amps.Nangona kunjalo, ulwakhiwo olutsha lwekhaya lubandakanya iisekethe zoluhlu lwe-50-amp, kuba ezi zanele uninzi lweendawo zokupheka zokuhlala.
Xa i-cooktop kunye ne-oven eludongeni ziziyunithi ezihlukeneyo kwiikhikhini, iKhowudi yoMbane yeSizwe ivumela ngokubanzi ukuba zombini iiyunithi zinikwe amandla yisekethe efanayo, ngaphandle kokuba umthwalo wombane odibeneyo awugqithisi umthamo okhuselekileyo weso sekethi.Nangona kunjalo, ngokwesiqhelo ukusetyenziswa kwe-2-, 30-, okanye 40- amp iisekethe ziqhutywa ukusuka kwipaneli ephambili ukunika amandla nganye ngokwahlukeneyo.
03. Isekethe yokucoca izitya
Xa ufaka i-dishwasher, isiphaluka kufuneka sibe yi-120/125-volt ezinikeleyo, i-15-amp circuit.Lo mmandla we-15-amp wondliwa ngocingo lwe-14/2 NM kunye nomhlaba.Usenokukhetha ukondla umatshini wokuhlamba izitya ngesekethe ye-amp engama-20 usebenzisa ucingo lwe-12/2 lwe-NM olunomhlaba.Nceda uqinisekise ukuba uvumela ukucotha okwaneleyo kwintambo ye-NM ukuze umatshini wokuhlamba izitya ube nokutsalwa ngaphandle kwaye unikwe inkonzo ngaphandle kokuwuqhawula—umlungisi wesixhobo sakho uya kukubulela.
Qaphela: oomatshini bokuhlamba izitya baya kufuna indlela yoqhawulo lwasekhaya okanye ukutshixelwa kwephaneli.Le mfuno iphunyezwa ngentambo kunye noqwalaselo lweplagi okanye isixhobo esincinci sokutshixa esifakwe kwi-breaker kwipaneli ukunqanda ukothuka.
Abanye abantu abasebenza ngombane baya kufaka ucingo ekhitshini ukuze umatshini wokuhlamba izitya kunye nokulahlwa kwenkunkuma kunikwe amandla yisekethe enye, kodwa ukuba oku kuyenziwa, kufuneka kube yisekethe ye-20-amp kwaye kufuneka kuthathelwe ingqalelo ukuqinisekisa ukuba umndilili opheleleyo wazo zombini izixhobo awudluli. I-80 yepesenti ye-circuit amperage rating.Kufuneka ukhangele kunye nabasemagunyeni bekhowudi yendawo ukuze ubone ukuba oku kuvunyelwe.
Iimfuno ze-GFCI kunye ne-AFCI ziyahluka ukusuka kulawulo ukuya kulawulo.Ngokuqhelekileyo, isekethe ifuna ukukhuselwa kwe-GFCI, kodwa ukuba ukhuseleko lwe-AFCI luyafuneka okanye aluyi kuxhomekeka ekutolikeni kwendawo yekhowudi.
04. ISekethe yokuLahla iNkunkuma
Ukulahla inkunkuma kwenza umsebenzi wokucoca ukungcola emva kokutya.Xa bethwele inkunkuma, basebenzisa indawana epholileyo njengoko becola inkunkuma.Ukulahlwa kwenkunkuma kufuna isiphaluka esizinikezeleyo se-15-amp, esondliwe yintambo ye-14/2 ye-NM enomhlaba.Unokukhetha kwakhona ukondla i-diposer ngesekethe ye-20-amp, usebenzisa i-12/2 yocingo lwe-NM kunye nomhlaba.Oku kudlalwa rhoqo xa ikhowudi yendawo ivumela ukulahlwa ukwabelana ngesiphaluka kunye ne-dishwasher.Kufuneka usoloko ujongana nomhloli wokwakha wengingqi yakho ukuze ubone ukuba oku kuvumelekile na kwindawo yakho.
Imimandla eyahlukeneyo yolawulo inokuba neemfuno ezahlukeneyo ezifuna ukhuseleko lwe-GFCI kunye ne-AFCI yokulahlwa kwenkunkuma, ngoko ke nceda uqhagamshelane nabasemagunyeni basekuhlaleni malunga noku.Kubandakanya zombini i-AFCI kunye nokhuseleko lwe-GFCI yeyona ndlela ikhuselekileyo, kodwa ngenxa yokuba ii-GFCI zinokuthambekela "ekukhubekeni kwe-phantom" ngenxa yesantya sokuqalisa iimoto, ingcali yombane idla ngokuyishiya i-GFCIs kwezi sekethe apho iikhowudi zasekhaya zivumela oko.Ukukhuselwa kwe-AFCI kuya kufuneka ekubeni ezi zijikelezo zisebenza ngokutshintsha eludongeni kwaye ukulahlwa kunokutsalwa kwiplagi yokuphuma eludongeni.
05. Isekethe ye-Oven yeMicrowave
I-oven microwave idinga i-20-amp ezinikeleyo, isekethe ye-120/125-volt ukuyityisa.Oku kuya kufuna i-12/2 yocingo lwe-NM olunomhlaba.Ii-oveni ze-microwave ziza kwiindidi ezahlukeneyo kunye nobukhulu, oko kuthetha ukuba ezinye ziyimodeli ye-countertop ngelixa ezinye ii-microwaves zinyuka ngaphezulu kwesitovu.
Nangona kuqhelekile ukubona ii-oveni zemicrowave ziplagiwe kwizixhobo eziqhelekileyo zombane, ii-oveni zemicrowave ezinkulu zinokutsala kangange-1500 watts ngoko zidinga iisekethe zazo ezizinikeleyo.
Le sekethi ayifuni ukhuseleko lwe-GFCI kwiindawo ezininzi, kodwa ngamanye amaxesha iyafuneka apho isixhobo sombane siplaga kwindawo efikelelekayo.Ukhuseleko lwe-AFCI ludla ngokufuneka kule sekethi kuba isixhobo sombane siplagiwe kwindawo yokuphuma.Nangona kunjalo, ii-microwaves zifaka isandla kwimithwalo ye-phantom, ngoko unokucinga ngokuyikhupha xa ingasetyenziswa.
06. Ukukhanyisa iSekethe
Ngokuqinisekileyo, ikhitshi ayiyi kugqitywa ngaphandle kwesekethe yokukhanyisa ukukhanyisa indawo yokupheka.Enye i-15-amp, i-120/125-volt yesekethe ezinikeleyo iyafuneka ubuncinci ukunika amandla izibane zasekhitshini, ezifana nezixhobo zesilingi, izibane ze-canister, izibane ezingaphantsi kwekhabhinethi, kunye nezibane ze-strip.
Iseti nganye yezibane kufuneka ibe nokutshintsha kwayo ukukuvumela ukuba ulawule ukukhanya.Unokufuna ukongeza ifeni yesilingi okanye mhlawumbi ibhanki yezibane zomzila kwixesha elizayo.Ngesi sizathu, luluvo oluhle ukufaka isekethe ye-20-amp yokusetyenziswa kokukhanya ngokubanzi, nangona ikhowudi ifuna kuphela isekethe ye-15-amp.
Kwiindawo ezininzi zolawulo, isekethe ebonelela ngezibane zokukhanyisa kuphela ayifuni ukhuseleko lwe-GFCI, kodwa inokufuneka ukuba iswitshi eludongeni ibekwe kufutshane nesinki.Ukhuseleko lwe-AFCI luyimfuneko ngokubanzi kuzo zonke iisekethe zokukhanyisa.
07. IiSekethe zeZixhobo ezincinci
Uzakufuna iisekethe ezimbini ezizinikeleyo ezingama-20-amp, 120/125-volt kwi-counter-top yakho ukuze uqhube imithwalo yakho yombane emincinci, kuquka izixhobo ezifana neetoasta, iigridi zombane, iimbiza zekofu, iiblenders, njl. njl. Iisekethe ezimbini ezifunekayo ubuncinane ngekhowudi ;ungafaka ngakumbi ukuba iimfuno zakho ziyazifuna.
Nceda uzame ukucinga ukuba uya kubeka phi izixhobo zombane kwi-countertop yakho xa ucwangcisa iisekethe kunye nendawo yeendawo zokuthengisa.Ukuba uyathandabuza, yongeza iisekethe ezongezelelweyo kwixesha elizayo.
Iisekethe ezisebenzisa iplagi-in izitya ezisebenza kwi-countertop kufunekarhoqobabe zombini i-GFCI kunye ne-AFCI yokhuseleko lokuqwalaselwa kokhuseleko.
