Ithini intambo engu-14/2 esetshenziselwa (Manuwali)

Izintambo zikagesi zitholakala ngobukhulu obuhlukahlukene namageji ukuze zihambisane nesilinganiso somjikelezo. Ngayinye yazo inenjongo ethile namandla, kanti ucingo luncane/luncane, kuphakama inombolo. Emsebenzini kagesi wokuhlala, izintambo ze-10-gauge kanye ne-12-gauge zivame ukusetshenziswa, futhi kulesi sihloko sixoxa nge-14-gauge, ikakhulukazi i-14/2, ngokuningiliziwe.

Ngakho-ke ake sihlolisise ukuthi i-wire 14 isetshenziselwa ini kanye neminye imininingwane mayelana nomthamo nokuphepha kwayo.

Ukusebenzisa ucingo 14/2

Osayizi bezintambo abahlukene bafanela izinhlelo zokusebenza ezahlukene ekhaya lakho. Isibonelo, intambo engu-14/2 ivamise ukusetshenziselwa ukunika amandla izitolo zamandla aphansi, amalambu, nezinto zokukhanyisa kumasekethe angu-15 amp. Lona umkhawulo wamanje intambo engu-14/2 engawuphatha futhi inikeze amandla anele. Ngakho-ke, inqobo nje uma ixhumeke kumjikelezo we-amp angu-15, ungayisebenzisa ngokuphephile ngocingo oluyi-14/2. Kodwa-ke, uma ingaphezulu kwama-amps ayi-15, njengakusekethe engama-amp angu-20, intambo yakho engu-14/2 ingase inganikezi amandla anele, okukubeka engcupheni yokushaqeka kagesi. Kulokhu, udinga ukuthuthukela ocingweni oluqinile, oluwugqinsi njengocingo lwe-gauge engu-12/2.

Ukuqonda izintambo ezingu-14/2

Ngocingo lukagesi lwe-14/2, inombolo engu-14 ibonisa ingxenye yesiphambano somqhubi, futhi inombolo yesi-2 ibonisa inani labaqhubi kukhebula. Intambo engu-14/2 intambo kagesi eboshwe ngamakhondatha kagesi angama-14-gauge:

• Izintambo ezimnyama nezimhlophe "ezishisayo" - zithwala zamanje zisuka kuphaneli ziye entweni, okungaba iswishi, i-outlet, isibani noma into esetshenziswayo. Kukhona eminye imibala yezintambo ezishisayo, nakuba ingavamile kakhulu.
• Intambo ephansi, intambo yethusi eluhlaza noma engenalutho - Uma kwenzeka iphutha eliphansi, intambo yaphansi inikeza indlela yokubuyisela iphutha lamanje kuphaneli, ivule isinqamuli noma ishaye i-fuse, futhi ivale amandla.

Плюсы

• Lokhu ishibhile kunezintambo zikagesi eziyi-12/2 nezinye izintambo zikagesi eziwugqinsi.
• Ivumelana nezimo, okwenza kube lula ukusebenza nayo.

Минусы

• Intambo ye-gauge engu-14/2 kusekethe ye-amp engu-15 inikeza amandla anganele okusebenzisa ngokuphephile nangokuphumelelayo amayunithi e-AC, amathuluzi kagesi, nezinye izinto zikagesi.
• Uma usebenzisa i-14 gauge wire futhi ufuna ukuthuthukisa i-outlet ibe ama-amps angu-20 kamuva, udinga ukuyihlephula kuqala bese uyibuyisela esikhundleni ngocingo lwe-gauge engu-12, umsebenzi omningi wokufaka izintambo lowo.

Izinyathelo zokuphepha

Izintambo eziyi-14 gauge kanye namasekethe angu-15 amp angeke asetshenziswe kuyo yonke indawo yakho ngoba ezinye izinto zasendlini nemishini kagesi zidinga ama-amps angama-20 njengeziphephetha-moya zamafasitela, amavacuum esitolo, njll. yokugezela, ngaphandle kanye negalaji. Njengomphumela, uzodinga futhi ukufaka i-20/12 gauge wire esikhundleni se-2/14 gauge wire ukuze unikeze amandla anele nogesi wesekethe yakho engu-2 amp. Abakhi abaningi bezindlu basebenzisa i-20 gauge wire ukuxhuma zonke izitolo kuma-circuits angu-12 amp.

Imibuzo evame ukubuzwa

Iliphi inani eliphezulu lamanje elingathwalwa intambo engu-14/2 ngokuphepha? 

Izintambo ezingu-14/2 ziphephile ukusetshenziswa kumasekhethi afika ku-15 amps. Ukusebenzisa intambo engu-14/2 kuma-amps angaphezu kuka-15, njengakumjikelezo wama-amp angu-20, akuphephile. Ngakho-ke, ukuze ube ne-wiring kagesi ephephile, kungcono ukhethe i-wire gauge efanele ngokusekelwe okwamanje kumjikelezo.

Ngingawathola kanjani amandla amanje esekethe yami?

Thola futhi uvule ibhokisi lokushintsha ukuze unqume ukuphakama kwesekethe osebenza nayo. Okulandelayo, thola iswishi elawula ugesi endaweni yakho. I-amperage kufanele ikhonjiswe esibanjeni sesishintshi. Iswishi engu-15 amp ibhalwe ukuthi "15" futhi i-20 amp switch ibhalwe "20". Izifunda ezinika amandla izinto zikagesi ezinkulu kungenzeka zifakwe izinombolo eziphezulu.

Kwenzekani uma ngisebenzisa intambo engu-14/2 kusekethe engama-20 amp? 

I-14 gauge wire ayiklanyelwe ukuthwala umthamo ongaka. Uma uphoqa intambo yegeji engu-14 ukuthi idwebe ama-amps angu-20 wamanje, ishisa ngokweqile, ibangele ukuthi iswishi ihambe noma ugesi uthungele. Okungcono kakhulu, i-circuit breaker izohamba ukuze igweme ukushisa okuyingozi, kodwa izolahlekelwa amandla kumjikelezo. Esimeni esibi kakhulu, isekethe ye-amp engu-20 enezintambo eziyi-14 gauge izoshisa kakhulu ize ibangele umlilo kagesi. (1)

Mangaki amasokhethi angasekela izintambo ezingu-14/2?

Ngesekethe yakho engu-15 amp exhunywe nentambo yethusi engu-14/2, ungakwazi ukuxhuma kufika ezindaweni zikagesi eziyisishiyagalombili. Izitolo eziningi zinezindawo ezimbili, nakuba ezinye zinezine. Usebenzisa intambo kagesi eyigeji engu-14, ungaxhuma amasokhethi amane anesokhethi angu-2 noma amasokhethi amabili anesokhethi angu-4 kusekethe eyodwa engu-15-amp. Kodwa-ke, uma uhlose ukunika amandla ngokuphephile ama-outlet angaphezu kwayisishiyagalombili, cabanga ukushintshela kumjikelezo we-amp angu-20 enezintambo ezishubile, njengentambo yegeji engu-12.

Ingabe i-Romex 14/2 ingasetshenziswa ukuhlanganisa amasokhethi?

Intambo kagesi ye-Romex ayilutho ngaphezu kocingo oluyigeji elingu-14 olusongwe emgodleni ongeyona eyensimbi. Lokhu kunamathela kusiza ukudonsa ikhebula kuma-conduit ngokushesha, kodwa akuphazamisi ikhono lentambo ukuqhuba ugesi. I-Romex 14/2 kanye ne-14/2 evamile ziyafana futhi zinamandla afanayo. Njengomphumela, ikhebula le-Romex 14/2 lingasetshenziswa kumasekhethi lapho intambo evamile engu-14/2 ingasetshenziswa ngokuphephile. Lokhu kusho ukuthi i-14/2 Romex ingakwazi futhi ukunika amandla izitolo kumjikelezo we-15 amp. Kodwa-ke, kufanele futhi usebenzise ikhebula le-Romex eliqinile lapho uxhuma amasokhethi kusekethe enama-amps angaphezu kuka-15 ngokuhambisana namakhodi kagesi. (2)
