Iwugqinsi kangakanani i-12 gauge wire?

I-wire gauge isilinganiso sobubanzi bezintambo zikagesi. I-12 gauge wire iwucingo olukhethayo olumaphakathi lokudluliselwa kwamanje. Izintambo eziyi-12 zegeji zingathwala kufika kuma-amps angama-20. Ukweqa ukunikezwa kwamanje ocingweni kuzoyibangela ukuthi ingasebenziseki.

Kulo mhlahlandlela, sizongena emininingwaneni eyengeziwe mayelana nobukhulu be-12 gauge wire kanye nezici zayo.

Ngingalusebenzisa kuphi i-12 gauge wire? Isetshenziswa emakhishini, ezindlini zangasese nasezitsheni zangaphandle. I-air conditioner engu-120 volt esekela ama-amps angu-20 ingase isebenzise izintambo eziyi-12 gauge.

I-12 gauge wire diameter ngu-2.05 mm noma 0.1040 in. Imethrikhi ye-SWG. Banokumelana okuphansi kokugeleza kwamanje futhi bangakwazi ukuphatha ama-amps angu-20.

Iyini i-12 gauge wire?

Njengoba kushiwo ngenhla, intambo yegeji engu-12 ingu-2.05 mm (0.1040 in.) kumethrikhi ye-SWG. Ukumelana kwabo kuphansi kakhulu, okubenza babe ama-conductor alungele ukudluliswa kwamandla kagesi.

Asetshenziswa emakhishini, ezitsheni ezingaphandle, ezindlini zangasese, kanye nama-air conditioner angu-120 volt (20 amp). Njengomthetho, izintambo eziningi ezincane zingaxhunywa kunezintambo ezinkulu.

Izintambo eziyi-12 gauge zingabathumeli bamandla abaphumelelayo, ikakhulukazi lapho kudingeka khona ugesi omkhulu. Ngakho-ke, ngincoma ukusebenzisa i-12 gauge wire ukuze uthole ukudluliswa kwamandla okungcono.

Empeleni, ikhwalithi yocingo ayihlobene kakhulu nosayizi wocingo. Kodwa-ke, ngocingo oluyigeji engu-12 (igeji encane), izintambo zikagesi ezisebenza kakhulu zingatholakala. Ukumelana kwabo nakho kuphansi, ngokuvamile kungaphansi kuka-5% wokumelana okuphelele. Ungalahlekelwa kuphela ngu-1.588 ohms ngamafidi angu-1000 we-12 gauge copper wire. Ungasebenzisa futhi i-12 gauge flexible wire ngesipika esingu-4.000 ohm. Ngiphinde ngincome ukusebenzisa i-12 gauge copper wire esikhundleni se-12 gauge aluminium. Izintambo ze-aluminium ziqinile futhi zine-conductivity encane.

Isilinganiso samanje sezintambo eziyi-12 gauge

Inombolo enkulu yama-amps engaphathwa ngocingo lwegeji engu-12 ngama-amps angama-20. Futhi ama-amps angu-20 angathwalwa amamitha angu-400 ngocingo lwethusi oluyi-gauge engu-12. Uma ubude bezintambo budlula amafidi angu-400, ukulahlekelwa kwamandla kagesi kuqala ukwenzeka. Ukwenyuka kwamandla kagesi kuxazulula inkinga. Intambo enkulu ingakwazi ukuthwala i-current kumabanga amade kunocingo oluncane.

Eqinisweni, izintambo eziyi-12 zegeji, nakuba zilinganiselwe ama-amps angu-20, zingakwazi ukuphatha ama-amps angu-25. Kodwa-ke, qaphela ukuthi izilinganiso eziphezulu ze-ampere zingashisa izintambo zakho kanye ne-circuit breaker. Kuyaphawuleka ukuthi izinga lokushisa eliphakeme kakhulu, i-ampere ephezulu. Ngalo mqondo, izintambo ze-aluminium zine-conductivity ephansi kunezintambo zethusi; ngakho-ke bazophatha ama-amps aphansi uma kuqhathaniswa nezintambo zethusi njengoba isilinganiso sokushisa sikhuphuka.

Ubukhulu bentambo 12 gauge

Njengoba kushiwo ngaphambili, i-12 gauge wire ingu-2.05mm (ububanzi). Igeji nokuqina kwentambo kuhlobene. Izinzwa ezizacile zinokumelana kwamanje okuphezulu. Njengoba i-voltage incike ngokungaqondile kumanje, ukwehla kwamandla ezintambo ezincanyana kudala ukwanda okuhambisanayo kwamandla kagesi kuyo yonke intambo. Incazelo eqondile yalokhu kuchezuka ukuthi izintambo ezizacile zinenani eliphansi le-electron charge. Ama-electron abathwali be-conductivity kagesi. Izintambo eziwugqinsi zine-electron ephezulu yokushaja. (2)
