Zingaki izitolo ezisemshinini we-15 amp?
Okuqukethwe
Uma kuziwa ekufakeni izintambo ekhaya lakho, ufuna ukuqinisekisa ukuthi unenombolo efanele yezitolo namaswishi. Nakhu ukuthi mangaki ama-amps i-15 amp circuit breaker yakho okufanele ikwazi ukuwaphatha.
Nakuba kungekho mkhawulo enanini lezitolo ongaxhuma ku-breaker circuit, kungcono ukufaka kuphela inombolo enconywayo. Okunconyiwe kwamanje kokuphuma ngakunye kungu-1.5 amps. Ngakho-ke, uma ufuna ukusebenzisa amaphesenti angama-80 kuphela angakwazi ukuphatha i-circuit breaker yakho, akufanele ube nezitolo ezingaphezu kuka-8.
Lo mthetho wama-80% utholakala kuKhodi Kagesi Kazwelonke (NEC) futhi usebenza ekulayisheni okungashintshi. Lona umthwalo ohlala ufana amahora angu-3 noma ngaphezulu. I-circuit breaker yakho ingasetshenziswa kufika ku-100% wesikhathi, kodwa okwesikhashana kuphela.
Iyini inhloso yokukhawulela inani lezitolo ku-circuit breaker?
I-15 amp circuit breaker ingaba nezitolo eziningi ngendlela ofuna ngayo, kodwa ungasebenzisa ezinye zazo ngesikhathi. Lokhu kungenxa yokuthi isifunda sakho singaphatha kuphela ama-amps angu-15. Uma uxhuma i-amp iron engu-10 kanye ne-toaster engu-10 amp ngesikhathi esifanayo, ukulayishwa ngokweqile kuzokhubaza i-circuit breaker.
Sebenzisa amaswishi ahlukene engxenyeni ngayinye yendlu yakho ukuze uvimbele lokhu ukuthi kungenzeki. Kuye ngokuthi mangakanani amandla ocabanga ukuthi igumbi ngalinye lizowadinga, ungasebenzisa i-15 amp noma 20 amp circuit breaker ngosayizi wentambo onconywayo.
Ama-Circuit breaker abalulekile ekugcineni ikhaya lakho noma isakhiwo sakho siphephile. Ama-Circuit breaker awasona nje isici sokuphepha kuwo wonke amakhaya, kodwa futhi adingwa ngumthetho ukuvimbela ukugcwala kukagesi nemililo. Futhi, ikhaya lakho kufanele libe ne-circuit breaker engaphezu kweyodwa ukuze ugweme ukulayisha ngokweqile isekethe eyodwa ngemishini eminingi kakhulu.
Mangaki ama-outlet angaba sesekethe?
I-NEC kwesinye isikhathi ivumela isekethe ukuthi isebenze ngamandla aphelele we-breaker circuit. Lokhu kungenxa yokuthi ukugeleza okuqhubekayo komsinga omkhulu kangaka ngokusebenzisa izintambo kungaba yingozi.
Ukugijima ngamandla aphelele kuzoshisisa izintambo kusekethe, ezingancibilikisa noma zilimaze i-insulation ezungeze izintambo. Ukwenza kanjalo kungase kubangele ukujikeleza okufushane, okungase kubangele umlilo noma ukushaqeka kukagesi, okungase kubulale.
Ungasebenzisa amasekhethi akho ngamandla amakhulu e-circuit breaker isikhathi esifushane. I-NEC ithi esikhathini esiningi isikhathi esincane amahora amathathu noma ngaphansi. Uma kuyinde, wephula imithetho kagesi futhi ufaka ikhaya nomndeni wakho engozini.
Esinye isizathu sokuthi umkhawulo ungama-80% wamandla aphelele we-circuit breaker yingoba i-NEC ikholelwa ukuthi abantu abalayisha kakhulu izindawo zikagesi banika amandla izinto eziningi ngesitolo esisodwa.
Usebenzisa ifomula engezansi, ungakwazi ukubala ukuthi zingaki izitolo ongaba nazo kusekethe engu-15 amp ngaphandle kokweqa u-80% womkhawulo wokulayisha.
(15 A x 0.8) / 1.5 = 8 izitolo
Abanye abantu abenza ama-multi-plug noma ama-extension plugs bengeza izici zokuphepha kubo, kuyilapho abanye bengazenzi. Lawa mapulaki angakwazi ukulayisha ngokweqile isekethe futhi aphule ikhodi kagesi ngokuhlala edlula igagasi elingaphezu komkhawulo ka-80% nge-breaker circuit.
Wazi kanjani ukuthi ulayisha kakhulu isekethe?
Ngaphandle kophawu olucacile lwe-15 amp circuit breaker ehamba njalo, wazi kanjani uma ulayisha kakhulu isekethe ngokusebenzisa amadivaysi amaningi ngesikhathi esisodwa?
Izibalo ezilula zizokusiza uthole impendulo. Ama-Watts ahlukaniswe ngamaVolts anikeza iyunithi i-Ampere. Amakhaya amaningi asebenza ku-120 volt AC, ngakho siyawazi amandla kagesi. Sebenzisa isibalo esilandelayo ukubala ukuthi mangaki ama-watt esingawasebenzisa kusekethe.
15 amps = W / 120 volts
W = 15 amps x 120 volts
Amandla aphezulu = 1800W
Ngale fomula, singakwazi ukunquma ukuthi mangaki ama-watts isekethe eyodwa engawaphatha. Kodwa singasebenzisa kuphela kufikela ku-80% walokho okungaphathwa yi-circuit breaker. Ungakuqonda ngokuthi:
1800 x 0.8 = 1440 W
Izibalo zethu zibonisa ukuthi i-1440 W ingamandla amakhulu angasetshenziswa kusekethe isikhathi eside. Uma ungeza amandla akho konke okuxhunywe kusokhethi ngayinye kumjikelezo, amandla aphelele kufanele abe ngaphansi kwama-watts angu-1440.
Ubani onezitolo eziningi: isifunda esingu-15 amp noma isifunda esingu-20 amp?
Imithetho efanayo ingasetshenziswa ukuthola indlela yokubala i-20 amp circuit. Isekethe ye-amp engu-20 ikalelwe okwamanje kunesekethe engu-15 amp.
I-80% efanayo yamandla aphezulu we-circuit breaker ihlobene nesifunda se-20 A, ngakho-ke amasokhethi ayishumi yinani eliphezulu elingase libe kulo mjikelezo. Ngakho-ke isekethe engama-amp angama-20 ingaba nezitolo eziningi kunesekethe eyi-15 amp.
Usebenzisa umthetho wesithupha ofanayo wokuthi ku-1.5 A ngayinye engaphathwa yi-circuit breaker, kufanele kube khona indawo eyodwa, ungafinyelela eziphethweni ezilandelayo:
(20 A x 0.8) / 1.5 = 10 izitolo
Ingabe izibani namasokhethi kungaba kusekethe efanayo?
Ngobuchwepheshe, ungasebenzisa izibani namasokhethi kusekethe efanayo. I-breaker circuit ayiwazi umehluko phakathi kwamasokhethi nezibani; ibheka kuphela ukuthi ungakanani ugesi osetshenziswayo.
Uma wengeza izibani kuchungechunge lokuphumayo, uzodinga ukunciphisa inani lezindawo zokuphuma ngenani lezibani ozingezayo. Isibonelo, uma ungeza izibani ezimbili kusekethe engu-15A, ungaba nenani eliphakeme lamasokhethi ayisithupha kulowo mjikelezo.
Ngenkathi ungakwazi ukwengeza izinto zokukhanyisa endaweni yokuphuma, ngokuvamile akuwona umqondo omuhle wokuphepha nokuhlelwa kwephaneli ye-circuit breaker. Lokhu kungaba yingozi uma ungazi ukuthi yimaphi amapulaki nama-bulb akuyiphi isekethe.
Ngenxa yalesi sizathu, ezindlini eziningi, izintambo zifana nokuthi izitolo zisesekethe eyodwa futhi izibani zikwesinye.
Kwesinye isikhathi i-NEC iyakwenqabela ukusetshenziswa kwamapulaki nezibani kusekethe efanayo. Isibonelo, ezindlini zokugezela nasezimpahleni ezincane zasekhishini ezixhunywa kumasokhethi ngaphezu kwetafula.
Ungakwazi ukuxhuma ukukhanya endaweni ephuma odongeni, kodwa ngaphambi kokwenza kanjalo, kufanele ujwayele Ikhodi Kagesi Kazwelonke (NEC) kanye nemithethonqubo endaweni yangakini. Njengoba sekushiwo kakade, lo mkhuba unemikhawulo ethile, kuye ngokuthi igumbi ofuna ukukwenza kulo.
Ukuxuba amasokhethi nezakhiwo akukhuthazwa ngoba kwenza uhlelo lwezintambo lube nzima kunalokho okudingeka lube yikho.
Ukufingqa
Awukho umthetho oqinile futhi osheshayo mayelana nokuthi zingaki izitolo ongazixhuma kusekethe engu-15 amp, kodwa kufanele uxhume kuphela ama-watts angu-1440 wamandla ngesikhathi.
Futhi, ama-amps angu-1.5 endaweni ngayinye kuwumthetho omuhle wesithupha. Kodwa-ke, kufanele ume ku-80% yenani eliphelele le-circuit breaker ukuze i-circuit breaker ihlale isebenza. Kuma-amps ayi-15 sinikeza ubuningi bezitolo eziyi-8.
