Ukufingqa

Ngazo zonke izinhlobo zocingo kungase kudideke, ngilapha ukuze ngixoxe ngezinhlobo zocingo ezithakazelisa kakhulu, i-10/3 gauge wire inezinzuzo eziningi. Sizoxoxa ngalezi zinzuzo kulokhu okuthunyelwe futhi sichaze ukuthi ucingo lwe-10 3 lusetshenziselwa ini.

Ngokuvamile, ikhebula elingu-10/3 liza nezintambo ezibukhoma ezintathu zegeji engu-10 kanye nentambo yaphansi ye-gauge engu-10. Lokhu kusho ukuthi intambo engu-10/3 inenani lezintambo ezine. Le ntambo ivamise ukusetshenziselwa amasokhethi amaphini amane angu-220V. Ungathola le khebula engu-10/3 kuma-air conditioner, iziko lokuphekela ezincane nezomisa izingubo zikagesi.

Odinga ukukwazi mayelana ne-10/3 gauge wire

Uma ungayazi ikhebuli engu-10/3, lesi sigaba singase sibe usizo kuwe. ikhebula elingu-10/3 linezintambo ezintathu ezihlukene zokuqondisa kanye nentambo yaphansi. Zonke izintambo ezine ziyigeji engu-10.

Intambo ye-gauge engu-10 ijiyile kunegeji engu-14 kanye ne-12 gauge wire. Ngakho-ke, ikhebula elingu-10/3 linocingo olukhulu kunentambo engu-12/2. Nawa amanye amaqiniso athakazelisayo mayelana nezintambo ezingu-10/3-core.

Njengoba wazi kakade, u-10 uyigeji, futhi u-3 uyinombolo yezintambo zekhebula. Lokhu akubandakanyi intambo yaphansi. Ngokuvamile ikhebula elingu-10/3 liza nezintambo ezimbili ezishisayo ezibomvu nezimnyama. Intambo emhlophe iyintambo engathathi hlangothi futhi eluhlaza okwesibhakabhaka intambo yaphansi.

Bese ukhumbula: Intambo yaphansi ayihlali inokugquma okuluhlaza njalo. Kwesinye isikhathi ugcina usunocingo lwethusi olungenalutho.

Umehluko phakathi kwekhebuli engu-10/3 kanye nengu-10/2?

Njengoba wazi kakade, ikhebula le-10/3 linama-cores amane. Kodwa uma kukhulunywa ngekhebula elingu-10/2, linezintambo ezintathu kuphela. Lezi zintambo zihlanganisa intambo emhlophe engathathi hlangothi, intambo yaphansi eluhlaza, kanye nentambo ebukhoma emnyama. Noma i-diameter yekhebula ihlukile, osayizi bezintambo bayafana.

Intambo engu-10/3 isetshenziselwa ini??

Ikhebula elingu-10/3 lilungele i-220V, i-30 amp outlets. Lesi sokhethi se-pin esingu-220V siwusizo kakhulu kumasomisi kagesi, ama-air conditioner, ohhavini namahhavini amancane.

Kungani amasokhethi anamaphini amane ekhetheke kangaka?

Lawa masokhethi amaphini amane angaxhunywa kumasekhethi angu-120V noma angu-240V. Isibonelo, isekethe engu-120V inika amandla izinzwa zokomisa, izibali sikhathi, nezinye izinto zikagesi. Isekethe engu-240V inika amandla izinto zokushisisa. (1)

Ithiphu: Uma amadivayisi adinga ngaphezu kwama-amps angu-30, ikhebula elingu-10/3 ayanele kule ndawo. Ngakho-ke, sebenzisa izintambo ezingu-6/3 noma ezingu-8/3 zohlobo. Kokubili u-6/3 kanye no-8/3 banezintambo eziwugqinsi uma kuqhathaniswa no-10/3.

Iyini i-wire diameter 10/3?

Ikhebula elingu-10/3 lingu-0.66 amayintshi ububanzi. Futhi, i-10 gauge wire ingu-0.1019 amayintshi ububanzi. Ububanzi bekhebula elingu-10/3 bulingana nobubanzi bezintambo ezine zegeji engu-10, ukufakwa kwalezo zintambo, kanye nomgodla wekhebula.

Kodwa-ke, uma ucingo oluphansi lungafakwanga (ucingo lwethusi olungenalutho), ububanzi bekhebula bungancishiswa ngokufanele.

Bese ukhumbula: Ububanzi bekhebula bungahluka kuye ngezinto zokwakha, umkhiqizi kanye nokufakwa kocingo oluphansi.

Ingabe izintambo ezisindayo ezingu-10/3 zanele ukomisa?

Kwama-dryer amaningi, ucingo lwe-10/3 luyindlela enhle enikezwe ukuthi isomisi sidinga ama-amps angu-30 noma ngaphansi. Ngakho-ke, hlola i-amperage ngaphambi kokuxhuma isomisi kukhebula engu-10/3 bese uqinisekisa ukuthi isokhethi enamaphini amane angu-220V isilungile.

Ithiphu: I-Overcurrent ingase ibangele i-circuit breaker futhi ngezinye izikhathi ibangele umlilo. Ngakho-ke, landela njalo izincomo ezingenhla uma usebenzisa ikhebula le-10/3.

I-voltage yekhebula yehla ngo-10/3

Ngaphambi kokuxhuma ikhebula le-10/3 kumshini wokomisa, kuhle ngaso sonke isikhathi ukuhlola ukwehla kwamandla kagesi. Uma kucatshangelwa ukwehla kwamandla kagesi aphezulu ngo-3%.

Ngokunikezwa kwamandla esigaba esisodwa 120 V, 30 A:

Intambo engu-10 AWG iyakwazi ukuthwala amafithi angu-58 wamanje ngaphandle kokudlula imikhawulo yokwehla kwamandla kagesi. Zama ukuyigcina icishe ibe ngamafidi angama-50.

Ngokunikezwa kwamandla esigaba esisodwa 240 V, 30 A:

Intambo engu-10 AWG iyakwazi ukuthwala amafithi angu-115 wamanje ngaphandle kokudlula imikhawulo yokwehla kwamandla kagesi. Zama ukuyigcina icishe ibe ngamafidi angama-100.

Vula ngoba I-voltage drop calculator.

Ingabe izintambo ezingu-10/3 zingasebenza ngaphansi komhlaba?

Yebo, ukusetshenziswa komhlabathi ikhebula elingu-10/3 kuyisinqumo esihle kakhulu. Nokho, ukuze usebenzise ikhebula elingu-10/3 ngaphansi komhlaba, uzodinga izinto ezimbili.

Ikhebula 10/3uF
imigudu

Okokuqala, uma uhlela ukungcwaba ucingo, uzodinga iziteshi eziningana. Bese uthenga izintambo ezingu-10/3 ngenketho yokuphakelayo komhlaba. Lezi zintambo zenzelwe ngokukhethekile ukusetshenziswa ngaphansi komhlaba. Ngokuvamile izintambo ze-UV zinqanyulwa nge-thermoplastic eqinile. Nazi izinto ezimbalwa ezibalulekile okufanele uzicabangele lapho ungcwaba intambo engu-10/3 UF.

Cabangela ukwehla kwamandla kagesi. kufanele ibe ngaphansi kuka-3%.
Uma ugqiba izintambo ngamapayipi, zimbele okungenani ngamasentimitha angu-18 ukushona.
Uma ugqiba ucingo ngokuqondile, lungcwabe okungenani amayintshi angu-24.

Mangaki amasokhethi angafakwa ocingweni lwe-10/3?

Intambo engu-10/3 ikalelwe ama-amps angama-30. Kodwa-ke, ngokusho kwe-NEC, ungalungiselela kuphela ukuphuma kwe-30 amp eyodwa kumjikelezo we-30 amp.

Zingaki izindawo zokuphuma zesekethe engu-20 amp?

Ngokwe-NEC, noma iyiphi isekethe enikeziwe kufanele ithweswe umthwalo ongama-80% noma ngaphansi. Ngakho uma sicabanga ngalokhu,

Amandla adingekayo endaweni ngayinye =

Ngakho-ke

Inani lemiphumela =

Kumjikelezo wama-amp angu-20, izindawo eziyishumi ze-1.5 amp zingaxhunywa.

Ukufingqa

Ngaphandle kokungabaza, ikhebula elingu-10/3 liyinketho efanelekile yezitolo namasekethe angama-30 amp. Kodwa khumbula, noma nini lapho usebenzisa intambo engu-10/3, thatha izinyathelo zokuphepha ezidingekayo. Ubhekene nenani elibalulekile likagesi. Ngakho, noma yikuphi ukubala kabi kungaholela engozini ebulalayo. (2)
