Muaj pes tsawg qhov hluav taws xob nyob ntawm lub tshuab 15 amp?

Thaum nws los txog rau kev xaim hauv koj lub tsev, koj xav kom ntseeg tau tias koj muaj cov xov tooj ntawm qhov hluav taws xob thiab cov keyboards kom raug. Qhov no yog pes tsawg amps koj 15 amp Circuit Court breaker yuav tsum muaj peev xwm ua tau.

Thaum tsis muaj kev txwv rau tus naj npawb ntawm qhov hluav taws xob koj tuaj yeem txuas mus rau lub tshuab hluav taws xob, nws yog qhov zoo tshaj rau nruab tsuas yog tus lej pom zoo. Qhov pom zoo tam sim no rau ib qhov hluav taws xob yog 1.5 amps. Yog li, yog tias koj xav siv tsuas yog 80% ntawm qhov koj lub Circuit Court breaker tuaj yeem ua tau, koj yuav tsum tsis pub ntau tshaj 8 qhov hluav taws xob.

Txoj cai 80% no muaj nyob rau hauv National Electrical Code (NEC) thiab siv rau kev thauj khoom tas li. Qhov no yog qhov thauj khoom uas tseem zoo li qub rau 3 teev lossis ntau dua. Koj lub Circuit Court breaker tuaj yeem siv txog li 100% ntawm lub sijhawm, tab sis tsuas yog lub sijhawm luv luv xwb.

Lub hom phiaj ntawm kev txwv tus naj npawb ntawm qhov hluav taws xob ntawm lub Circuit Court breaker yog dab tsi?

Lub 15 amp Circuit Court breaker tuaj yeem muaj ntau qhov hluav taws xob raws li koj xav tau, tab sis koj tsuas tuaj yeem siv qee yam ntawm lawv ib zaug. Qhov no yog vim tias koj lub voj voog tsuas tuaj yeem ua tau txog li 15 amps. Yog tias koj txuas lub 10 amp hlau thiab 10 amp toaster tib lub sijhawm, lub overload yuav dhau mus rau lub Circuit Court breaker.

Siv cov keyboards sib txawv rau txhua qhov ntawm koj lub tsev kom tsis txhob muaj qhov no tshwm sim. Nyob ntawm seb lub zog npaum li cas koj xav tias txhua chav yuav xav tau, koj tuaj yeem siv 15 amp lossis 20 amp Circuit Court breaker nrog rau cov xaim loj.

Circuit Breakers yog qhov tseem ceeb rau kev ua kom koj lub tsev lossis lub tsev muaj kev nyab xeeb. Circuit Court breakers tsis yog tsuas yog muaj kev nyab xeeb rau txhua lub tsev, tab sis kuj yuav tsum tau raws li txoj cai los tiv thaiv hluav taws xob overloads thiab hluav taws kub. Tsis tas li ntawd, koj lub tsev yuav tsum muaj ntau tshaj ib lub Circuit Court breaker kom tsis txhob overloading ib Circuit Court nrog ntau yam khoom siv.

Muaj pes tsawg qhov hluav taws xob tuaj yeem ua rau hauv ib lub voj voog?

NEC tsuas yog qee zaum tso cai rau lub voj voog khiav ntawm lub zog tag nrho ntawm lub Circuit Court breaker. Qhov no yog vim qhov tsis tu ncua ntawm cov tam sim no loj heev los ntawm kev xaim tuaj yeem ua rau muaj kev phom sij.

Kev khiav ntawm lub zog tag nrho yuav ua rau cov kab hluav taws xob hauv lub voj voog, uas tuaj yeem yaj lossis puas tsuaj rau cov rwb thaiv tsev nyob ib ncig ntawm cov xov hlau. Ua li no yuav ua rau muaj hluav taws xob luv luv, uas yuav ua rau hluav taws kub lossis hluav taws xob poob, uas yuav ua rau tuag taus.

Koj tuaj yeem khiav koj cov circuits ntawm lub zog hluav taws xob ntau tshaj plaws rau lub sijhawm luv luv. NEC hais tias feem ntau lub sijhawm luv luv yog peb teev lossis tsawg dua. Yog tias ntev dua, koj ua txhaum txoj cai hluav taws xob thiab ua rau koj lub tsev thiab tsev neeg muaj kev phom sij.

Lwm qhov laj thawj qhov kev txwv yog 80% ntawm cov hluav taws xob hluav taws xob tag nrho yog vim NEC ntseeg tias cov neeg siv hluav taws xob ntau dhau yog siv ntau yam khoom los ntawm ib lub qhov hluav taws xob.

Siv cov qauv hauv qab no, koj tuaj yeem suav pes tsawg qhov hluav taws xob koj tuaj yeem muaj nyob rau hauv 15 amp Circuit Court yam tsis pub tshaj 80% ntawm qhov txwv.

(15 A x 0.8) / 1.5 = 8 qhov hluav taws xob

Qee tus neeg uas ua ntau lub ntsaws lossis txuas txuas ntxiv ntxiv kev nyab xeeb rau lawv, thaum lwm tus tsis ua. Cov plugs no tuaj yeem hla lub voj voog thiab ua txhaum cov cai hluav taws xob los ntawm kev hla tam sim no dhau ntawm 80% txwv los ntawm kev sib tsoo.

Yuav ua li cas koj paub tias koj overloading lub Circuit Court?

Ib cag ntawm qhov tsis pom kev tsis txaus ntseeg ntawm 15 amp Circuit Court breaker tripping nquag, koj yuav ua li cas paub yog tias koj overloading Circuit Court los ntawm kev khiav ntau yam khoom siv tib lub sijhawm?

Cov lej yooj yim yuav pab koj nrhiav cov lus teb. Watts faib los ntawm Volts muab cov chav Ampere. Feem ntau cov tsev khiav ntawm 120 volt AC, yog li peb paub qhov voltage. Siv cov kab zauv hauv qab no los xam seb peb siv tau pes tsawg watts hauv ib lub voj voog.

15 amps = W / 120 volts

W = 15 amps x 120 v

Lub zog siab tshaj plaws = 1800W

Nrog rau cov qauv no, peb tuaj yeem txiav txim siab pes tsawg watts ib lub voj voog tuaj yeem ua tau. Tab sis peb tsuas tuaj yeem siv txog li 80% ntawm qhov Circuit Court breaker tuaj yeem ua tau. Koj tuaj yeem nkag siab nws los ntawm:

Luas = 1800 x 0.8 = 1440 W

Peb cov kev suav suav qhia tias 1440 W yog lub zog siab tshaj plaws uas tuaj yeem siv rau hauv ib lub voj voog ntev. Yog tias koj ntxiv lub zog ntawm txhua yam txuas nrog txhua lub qhov hluav taws xob hauv Circuit Court, tag nrho lub zog yuav tsum tsawg dua 1440 watts.

Leej twg muaj ntau qhov hluav taws xob: 15 amp circuit lossis 20 amp circuit?

Tib txoj cai tuaj yeem siv los txheeb xyuas seb yuav suav li cas rau 20 amp circuit. Lub 20 amp Circuit Court yog ntsuas rau tam sim no ntau tshaj li 15 amp circuit.

Tib yam 80% ntawm lub zog siab tshaj plaws ntawm Circuit Court breaker yog cuam tshuam nrog 20 A Circuit Court, yog li kaum lub qhov hluav taws xob yog qhov siab tshaj plaws uas tuaj yeem ua rau hauv Circuit Court no. Yog li 20 amp Circuit Court tuaj yeem muaj qhov hluav taws xob ntau dua li 15 amp circuit.

Siv tib txoj cai ntawm tus ntiv tes xoo uas rau txhua txhua 1.5 A uas lub tshuab hluav taws xob tuaj yeem ua tau, yuav tsum muaj ib lub qhov hluav taws xob, koj tuaj yeem tuaj rau cov lus xaus hauv qab no:

(20 A x 0.8) / 1.5 = 10 qhov hluav taws xob

Lub teeb thiab qhov hluav taws xob puas tuaj yeem nyob ntawm tib lub voj voog?

Technically, koj tuaj yeem khiav teeb thiab lub qhov hluav taws xob ntawm tib lub voj voog. Lub Circuit Court breaker tsis paub qhov txawv ntawm cov qhov (socket) thiab teeb; nws tsuas saib seb puas siv hluav taws xob ntau npaum li cas.

Yog tias koj ntxiv cov teeb rau lub qhov hluav taws xob, koj yuav tsum tau txo cov qhov hluav taws xob los ntawm cov teeb uas koj ntxiv. Piv txwv li, yog tias koj ntxiv ob lub teeb rau 15A Circuit Court, koj tuaj yeem muaj qhov siab tshaj plaws ntawm rau lub qhov hluav taws xob hauv qhov hluav taws xob ntawd.

Thaum koj tuaj yeem ntxiv cov teeb pom kev zoo rau lub qhov hluav taws xob, nws feem ntau tsis yog lub tswv yim zoo rau kev ruaj ntseg thiab lub koom haum ntawm lub Circuit Court breaker vaj huam sib luag. Qhov no tuaj yeem ua rau muaj kev phom sij yog tias koj tsis paub cov plugs thiab qhov muag teev nyob rau ntawm qhov twg.

Vim li no, nyob rau hauv ntau lub tsev, cov xaim yog xws li cov qhov hluav taws xob nyob ntawm ib lub voj voog thiab lub teeb nyob rau lwm qhov.

Qee lub sij hawm NEC txwv tsis pub siv cov ntsaws thiab teeb hauv tib lub voj voog. Piv txwv li, hauv chav da dej thiab rau cov khoom siv hauv chav ua noj me me uas ntsaws rau hauv cov qhov (sockets) saum lub txee.

Koj tuaj yeem ntsaws lub teeb rau hauv lub qhov hluav taws xob phab ntsa, tab sis ua ntej koj ua li ntawd, koj yuav tsum paub txog National Electrical Code (NEC) thiab cov kev cai hauv koj cheeb tsam. Raws li twb tau hais lawm, qhov kev xyaum no muaj qee qhov kev txwv, nyob ntawm chav tsev uas koj xav ua.

Nws tsis pom zoo kom sib xyaw cov qhov (sockets) thiab cov khoom sib txuas vim nws ua rau cov kab hluav taws xob sib txuas ntau dua li qhov nws xav tau.

Summing txog

Tsis muaj txoj cai nyuaj thiab ceev ceev txog pes tsawg qhov hluav taws xob koj tuaj yeem ntsaws rau hauv 15 amp Circuit Court, tab sis koj tsuas yog yuav tsum ntsaws 1440 watts ntawm lub zog ib zaug.

Ib zaug ntxiv, 1.5 amps ib qhov hluav taws xob yog txoj cai zoo ntawm tus ntiv tes xoo. Txawm li cas los xij, koj yuav tsum nres ntawm 80% ntawm lub Circuit Court breaker tag nrho cov amperage rau lub Circuit Court breaker kom nyob twj ywm. Ntawm 15 amps peb muab qhov siab tshaj plaws ntawm 8 qhov hluav taws xob.

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