Ntev npaum li cas yog 18 gauge hlau?
Nws yog ib qho tseem ceeb heev kom paub qhov ntsuas ntawm koj cov xaim hluav taws xob. Kev siv cov xaim tsis raug rau cov khoom siv hluav taws xob tuaj yeem ua rau muaj kev phom sij. 18 gauge hlau muaj qhov ntsuas tam sim no ntawm 10-16 amps. Nws yog siv nyob rau hauv qis-voltage circuits xws li teeb pom kev zoo fixtures - 10 amperes.
Yuav ua li cas kom paub qhov thickness ntawm 18 gauge hlau? Koj tuaj yeem tshawb xyuas qhov ntsuas ampere lossis qhov tseeb ampere thickness qhia ntawm lub npog rwb thaiv tsev. 18 gauge xov hlau yog 0.048 nti tuab. Qhov no tuaj yeem hloov mus rau 1.024 hli. Thiab qhov siab tshaj plaws ntawm watts uas 18 gauge xov hlau tuaj yeem ua tau yog 600 watts. Koj tuaj yeem siv NEC Wire Thickness Calculator los xam 18 gauge hlau thickness.
Hauv phau ntawv qhia no, peb yuav muab cov rooj thiab cov kab kos los pab koj xyuas cov hlau tuab. Peb tseem yuav piav qhia thiab piav qhia txog lub tshuab xam zauv hlau thickness.
Hlau thickness 18 gauge
Raws li kuv nyuam qhuav hais, 18 gauge xov hlau yog 1.024 hli (0.048 nti) tuab. Lawv muaj qhov ntsuas tam sim no ntawm 16 amps. Txawm li cas los xij, qhov ntev ntawm cov hlau tseem cuam tshuam rau qhov ntsuas ampere. 18 gauge xov hlau tuaj yeem tuav 16 amps rau 12 "xaim. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev siv cov xov hlau loj dua tuaj yeem ua rau muaj peev xwm tam sim no. Qhov no yog vim lub fact tias lub ntsuas ntawm cov hlau hloov nyob rau hauv kev faib ua feem rau lub thickness.
Kuv pom zoo kom koj siv lub ntsuas hluav taws xob loj dua hauv cov teeb pom kev zoo thiab lwm yam hluav taws xob hauv koj lub tsev. Cov kab hluav taws xob loj dua ua rau kev xaim hluav taws xob hauv tsev kom zoo vim tias lawv tuaj yeem tswj cov kev ntsuas siab dua. Cov xaim me me tuaj yeem ua kom sov thiab qhov no ua rau hluav taws xob poob siab.
Tus naj npawb ntawm watts uas 18 gauge xov hlau tuaj yeem ua tau yog 600 watts (tseem hu ua wattage - tus nqi tam sim no ntawm lub ntsuas hluav taws xob tuaj yeem nqa tau). Amperage ntsuam xyuas rau 18 gauge thiab lwm yam gauge xov hlau muaj nyob rau hauv cov lus hauv qab no.
Hlau thickness rooj
Hauv AWG - American Wire Gauge system, qhov ntev thiab txoj kab uas hla ntawm lub xov hlau ntsuas yog xam los ntawm cov qauv:
Los ntawm cov qauv, peb tuaj yeem txiav txim siab tias rau txhua qhov rau qhov ntsuas ntawm cov hlau txoj kab uas hla ob npaug. Thiab rau txhua qhov peb calibers, qhov chaw hla ntu (CA) kuj ua ob npaug. Metric AWG hlau gauge muaj nyob rau hauv cov lus hauv qab no.
Hlau Thickness Tshuab xam zauv
Qhib rau Hlau thickness tshuab xam zauv.
Lub laij lej thickness yuav pab koj xam cov hlau thickness. Txhua yam koj yuav tsum tau ua yog nkag mus rau qhov tseem ceeb thiab xaiv hom hlau - piv txwv li, tooj liab lossis txhuas. Lub tshuab xam zauv hlau thickness yuav muab cov txiaj ntsig zoo rau koj los pab koj daws cov teeb meem ntsig txog kev suav hlau thickness. (1)
Wire Gauge Tshuab xam zauv Features
- Voltage qhov chaw - ntawm no koj tuaj yeem xaiv qhov voltage - 120, 240 thiab 480 volts.
- Tus naj npawb ntawm cov theem - feem ntau yog ib theem lossis peb theem. Ib-theem circuits yuav tsum tau 3 conductors, thiab peb-theem circuits yuav tsum tau 3 conductors. NEC txiav txim siab lub thickness ntawm conductors.
- Amps - Tam sim no kos los ntawm lub load yog muab los ntawm cov khoom tsim khoom. Ib qho ntawm NEC qhov yuav tsum tau muaj yog rau ib-theem circuits, tam sim no yuav tsum yog 1.25 npaug ntawm cov khoom thauj tam sim no.
- Tso cai voltage poob, AED - koj tuaj yeem nkag AVD rau hauv lub laij lej thiab tau txais 18 ntsuas hlau tuab.
Ceeb toom: Koj yuav tsum ua raws li NEC cov lus qhia thaum siv lub laij lej kom tau txais txiaj ntsig zoo.
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
- Cov hlau twg yog los ntawm lub roj teeb mus rau qhov pib
- Yuav ua li cas loj hlau rau 30 amps 200 ko taw
- Dab tsi yog qhov loj ntawm cov hlau rau lub qhov cub hluav taws xob
