Ntev npaum li cas koj tuaj yeem khiav 10/2 Hlau (Length vs Resistance)
Txheem
Yog tias koj xav paub ntau npaum li cas koj tuaj yeem xa xov 10/2 xaim hauv koj qhov project thaiv tsis muaj kev cuam tshuam rau amperage koj nyob rau hauv qhov chaw.
50 ft. lossis 15.25 meters ntawm qhov ntau. Kev khiav ntawm 10/2 xaim tshaj 50 ko taw tuaj yeem txo cov amps thiab tag nrho cov hluav taws xob tso tawm ntawm 10/2 xaim. Raws li qhov ntev ntawm cov hlau txuas ntxiv, yog li qhov kev tawm tsam uas cuam tshuam rau qhov tsis sib haum xeeb ntawm tus nqi lossis electrons. Raws li ib tug hluav taws xob, kuv yuav qhia koj nyob deb npaum li cas koj yuav tsum ncua ib tug 10/2 hlau nyob rau hauv kom meej.
Qhov deb tshaj plaws koj tuaj yeem xov 10/2 xaim (piv txwv li ob qhov sib txuas ntawm kaum lub ntsuas hluav taws xob nrog cov xaim hauv av ntxiv) yam tsis muaj kev cuam tshuam rau amperage yog 50 ft. Khiav lub 10/2 gauge tshaj 50 ft. tuaj yeem ua tau zoo kawg nkaus extenuate lossis txo qhov amps ntsuas ntawm txoj kab. Qhov ntev ntawm cov hlau sib txawv proportionally nrog kuj; Yog li, raws li kev tiv thaiv nce tus nqi ntim ceev txo. Ua tau zoo, tam sim no lossis amps txo qis.
Kuv mam li mus rau hauv ntau yam hauv qab no.
10/2 kab
10/2 cov xov hlau feem ntau yog siv los xaim cua txias uas xav tau kev siv cov xov hlau tshwj xeeb rau kev ua tau zoo. Lawv (10/2 xov hlau) tau pom zoo rau AC units vim tias lawv tuaj yeem tswj cov amps ntws hauv circuits yam xyuam xim.
10/2 xov hlau siv ob 10 gauge xov hlau nrog ib tug ua ke ampacity ntawm 70 amps. Cov hlau muaj ib qho 10 ntsuas kub hlau (dub), ib qho 10 ntsuas nruab nrab hlau (dawb), thiab ib qho av xaim rau kev ceev faj.
Lub ampacity ntawm ib tug tooj liab 10 gauge hlau yog kwv yees li 35 amps ntawm 75 degrees Celsius. Ua raws li 80 feem pua NEC txoj cai, xws li cov xaim tuaj yeem ua haujlwm hauv 28 amps circuit.
Yog li, lej, 10/2 xov hlau tuaj yeem muaj 56 amps. Hauv cov hlab ntsha ntawd, yog tias koj lub cuab yeej, hais lub tshuab cua txias, rub txog 50 amps; ces koj tuaj yeem siv 10/2 xaim los xaim.
Txawm li cas los xij, hauv phau ntawv qhia no, kuv yuav tsom mus rau qhov deb npaum li cas koj tuaj yeem ncav cuag kaum lub ntsuas hluav taws xob yam tsis muaj kev cuam tshuam rau amperage lossis lwm yam haujlwm ntawm 10/2 xaim.
Threading 10/2 Hlau
Cov nram qab no yog cov khoom uas tuaj yeem cuam tshuam raws li qhov ntev ntawm 10/2 xov hlau, lossis lwm yam xov hlau ntsuas, tau ncua:
Resistance & Hlau Length
Kuj nce nrog ntev.
Muaj kev sib raug zoo ntawm qhov ntev ntawm 10/2 xaim yuav tsum hla thiab tus nqi ntawm kev tiv thaiv tus nqi them.
Qhov tseem ceeb, raws li 10/2 xaim ntev nce tus nqi sib tsoo nce ua rau muaj kev nce ntxiv hauv kev tiv thaiv tam sim no. (1)
Amperage & Hlau Length
Qhov kev ntsuam xyuas amp ntawm 10/2 xaim tuaj yeem poob qis yog tias nws nthuav dav ntxiv.
Raws li tau hais los saum no, qhov nce hauv kev tiv thaiv yuav cuam tshuam ncaj qha rau qhov ntws ntawm cov hluav taws xob tam sim no. Tias yog vim li cas cov electrons tau tiv thaiv los ntawm ntws seamlessly los ntawm cov hlau.
Kub & Hlau Length
Cov lus hauv qab no teev cov ampacity ntawm ntau lub xov hlau ntsuas ntawm qhov ntev.
Yog li, Ntev npaum li cas koj tuaj yeem hla 10/2 Hlau?
Raws li AWG cov kev cai, 10/2 xaim tuaj yeem ncav cuag 50 ko taw lossis 15.25 meters, thiab nws tuaj yeem tuav txog 28 amps.
Lwm qhov kev siv ntawm 10/2 gauge hlau suav nrog cov hais lus, xaim hauv tsev, txuas txuas ntxiv, thiab lwm yam khoom siv hluav taws xob uas nws qhov kev ntsuas amps nyob rau hauv nruab nrab ntawm 20 thiab 30.
Cov lus nug nquag nug
Puas yog 10/2 thiab 10/3 xaim sib hloov tau?
10/2 xov hlau muaj ob kaum ntsuas xov hlau thiab ib lub hauv av xaim thaum 10/3 xov hlau muaj peb kaum ntsuas xov hlau ntxiv rau hauv av xaim.
Koj tuaj yeem siv 10/3 xaim ntawm 10/2 khiav, tsis suav nrog kaum qhov ntsuas thib peb (hauv 10/3 xaim). Txawm li cas los xij, koj tsis tuaj yeem siv 10/2 xov hlau ntawm lub cuab yeej uas xav tau 10/3 xov hlau (ob qhov kub, ib qho nruab nrab, thiab hauv av).
Ib tus tuaj yeem siv plaub-prong twist lock receptacle nrog 10/2 xaim?
Yog koj ua tau.
Txawm li cas los xij, koj yuav ua txhaum txoj cai thaiv kab hluav taws xob uas yuav tsum muaj tag nrho cov terminals ntawm lub connector uas siv AC lub hwj chim yuav tsum tau xaim raws li. Yog li, nws yog qhov zoo tshaj kom tsis txhob muaj qhov xwm txheej no vim tias lawv tuaj yeem ua rau tsis meej pem thiab muaj feem cuam tshuam txog hluav taws xob. (2)
