Ntev npaum li cas yog 12 gauge hlau?

Hlau gauge yog ib qho kev ntsuas ntawm txoj kab uas hla ntawm cov hluav taws xob. 12 gauge hlau yog qhov nruab nrab xaiv hlau rau kev hloov tam sim no. 12 gauge xov hlau tuaj yeem nqa mus txog 20 amps. Tshaj qhov khoom tam sim no rau cov xaim yuav ua rau nws siv tsis tau.

Hauv phau ntawv qhia no, peb yuav nkag mus rau hauv cov ncauj lus kom ntxaws txog qhov tuab ntawm 12 ntsuas hlau thiab nws cov yam ntxwv.

Kuv tuaj yeem siv 12 gauge hlau qhov twg? Nws yog siv hauv chav ua noj, chav dej thiab cov thawv sab nraum zoov. Lub tshuab cua txias 120 volt uas txhawb nqa 20 amps tuaj yeem siv 12 qhov ntsuas hluav taws xob.

12 gauge hlau txoj kab uas hla yog 2.05 hli los yog 0.1040 nyob rau hauv. SWG metric. Lawv muaj qhov tsis kam tiv thaiv tam sim no thiab tuaj yeem ua haujlwm txog li 20 amps.

Dab tsi yog 12 gauge hlau?

Raws li tau hais los saum no, 12 gauge hlau yog 2.05 mm (0.1040 in.) hauv SWG metric. Lawv qhov tsis kam yog tsawg dhau, uas ua rau lawv yooj yim conductors rau kev xa hluav taws xob tam sim no.

Lawv siv hauv chav ua noj, ntim sab nraum zoov, chav dej, thiab 120 volt (20 amp) cua txias. Raws li txoj cai, ntau cov xov hlau nyias nyias tuaj yeem txuas nrog ntau dua cov xov hlau tuab.

12 lub ntsuas hluav taws xob yog cov khoom siv hluav taws xob zoo, tshwj xeeb tshaj yog qhov yuav tsum muaj lub zog loj. Yog li, kuv pom zoo kom siv 12 gauge hlau rau kev hloov hluav taws xob zoo dua.

Hauv cov ntsiab lus, qhov zoo ntawm cov hlau tsis cuam tshuam nrog qhov loj ntawm cov hlau. Txawm li cas los xij, nrog 12 gauge (me me gauge) xaim, ntau cov hluav taws xob hluav taws xob tuaj yeem tau txais. Lawv kuj tseem tsawg, feem ntau tsawg dua 5% ntawm tag nrho cov kev tiv thaiv. Koj tsuas tuaj yeem poob 1.588 ohms ib 1000 ko taw ntawm 12 gauge tooj liab hlau. Koj tseem tuaj yeem siv 12 lub ntsuas hluav taws xob hloov pauv nrog 4.000 ohm hais lus. Kuv kuj pom zoo kom siv 12 gauge tooj liab hlau tsis yog 12 gauge txhuas. Aluminium hlau yog nruj thiab muaj tsawg conductivity.

Rated tam sim no rau 12 gauge xov hlau

Qhov siab tshaj plaws ntawm amps uas 12 gauge hlau tuaj yeem ua tau yog 20 amps. Thiab 20 amps tuaj yeem nqa 400 ko taw ntawm 12-gauge insulated tooj liab hlau. Yog tias cov hlau ntev tshaj 400 ko taw, qhov hluav taws xob poob pib tshwm sim. Kev nce qhov voltage daws qhov teeb meem. Ib lub xaim loj tuaj yeem nqa tam sim no ntev dua li cov xaim me me.

Hauv kev xyaum, 12 gauge xov hlau, txawm tias ntsuas rau 20 amps, tuaj yeem tuav txog 25 amps. Txawm li cas los xij, nco ntsoov tias qhov kev ntsuas ampere ntau dua tuaj yeem hlawv koj cov xov hlau thiab hluav taws xob hluav taws xob. Nws yog tsim nyog sau cia tias qhov siab dua qhov cua sov, qhov siab dua qhov ampere. Hauv qhov kev txiav txim siab no, cov xov hlau txhuas muaj qis dua cov xov tooj tooj liab; li no lawv yuav nqa cov amps qis dua piv rau cov xov tooj tooj liab raws li qhov ntsuas kub nce. (1)

Hlau thickness 12 gauge

Raws li tau hais ua ntej, 12 gauge hlau yog 2.05mm (inch). Kev ntsuas thiab hlau thickness muaj feem xyuam. Thinner sensors muaj zog dua tam sim no. Txij li thaum voltage yog indirectly nyob ntawm tam sim no, ib tug txo nyob rau hauv tam sim no nyob rau hauv thinner nyob ntawm tej ua rau ib tug sib raug nce nyob rau hauv lub voltage muaj peev xwm nyob rau hauv lub hlau. Qhov kev piav qhia meej rau qhov sib txawv no yog tias cov xov hlau nyias nyias muaj qhov qis dua electron ceev. Electrons yog cov khoom siv hluav taws xob conductivity. Thicker xov hlau muaj ib tug ntau dua electron charge ceev. (2)

Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.

• Ntev npaum li cas yog 18 gauge hlau
• Cov hlau twg yog los ntawm lub roj teeb mus rau qhov pib
• Nws puas tuaj yeem txuas cov xov hlau liab thiab dub ua ke
