Dab tsi yog 10/3 hlau siv rau?
Txheem
Nrog rau txhua hom hlau nws tuaj yeem ua rau tsis meej pem, Kuv nyob ntawm no los tham txog ib qho ntawm ntau hom xov hlau, 10/3 gauge hlau muaj ntau yam zoo. Peb yuav tham txog cov txiaj ntsig no hauv tsab xov xwm no thiab piav qhia tias 10 3 xaim siv rau dab tsi.
Feem ntau, 10/3 cable los nrog peb 10-gauge nyob xov hlau thiab 10-gauge av xaim. Qhov no txhais tau hais tias 10/3 cable muaj tag nrho ntawm plaub xov hlau. Cov kab hluav taws xob no feem ntau siv rau 220V plaub tus pin sockets.
Dab tsi koj yuav tsum paub txog 10/3 gauge hlau
Yog tias koj tsis paub txog 10/3 cable, tshooj no yuav pab tau koj. 10/3 cable muaj peb qhov sib txawv conductive xov hlau thiab av xaim. Tag nrho plaub kab yog 10 gauge.
10 gauge hlau yog tuab tshaj 14 gauge thiab 12 gauge hlau. Yog li ntawd, 10/3 cable muaj cov hlau tuab dua li 12/2 cable. Nov yog qee qhov tseeb ntxiv txog 10/3-core cables.
Raws li koj twb paub lawm, 10 yog qhov ntsuas, thiab 3 yog tus naj npawb ntawm cov cables. Qhov no tsis suav nrog hauv av xaim. Feem ntau, 10/3 cable los nrog ob lub xov tooj liab thiab dub kub. Dawb yog cov hlau nruab nrab thiab ntsuab yog av xaim.
Nco ntsoov: Cov hlau hauv av tsis tas yuav muaj cov rwb thaiv tsev ntsuab. Qee lub sij hawm koj xaus nrog liab qab hlau.
Qhov txawv ntawm 10/3 thiab 10/2 cable?
Raws li koj twb paub lawm, 10/3 cable muaj plaub cores. Tab sis thaum nws los txog rau 10/2 cable, nws tsuas muaj peb xaim. Cov xov hlau no muaj cov xaim dawb nruab nrab, cov xaim ntsuab hauv av, thiab cov hlau nyob dub. Txawm hais tias txoj kab uas hla ntawm kab sib txawv, qhov loj ntawm cov xaim yog tib yam.
Dab tsi yog 10/3 hlau siv rau??
10/3 cable yog zoo tagnrho rau 220V, 30 amp qhov hluav taws xob. Qhov 220V plaub tus pin socket no muaj txiaj ntsig zoo rau lub tshuab ziab khaub ncaws, cua txias, qhov cub thiab qhov cub me me.
Vim li cas plaub-pin sockets thiaj li tshwj xeeb?
Cov plaub-pin sockets no tuaj yeem txuas nrog 120V lossis 240V circuits. Piv txwv li, 120V Circuit Court powers tshuab ziab khaub ncaws, timers, thiab lwm yam khoom siv hluav taws xob. Lub 240V Circuit Court powers lub cua sov ntsiab. (1)
Tswv yim: Yog tias cov khoom siv xav tau ntau dua 30 amps, 10/3 cable tsis txaus rau lub qhov hluav taws xob no. Yog li ntawd, siv 6/3 lossis 8/3 hom cables. Ob leeg 6/3 thiab 8/3 muaj cov xov hlau tuab dua piv rau 10/3.
Dab tsi yog txoj kab uas hla 10/3?
Lub 10/3 cable yog 0.66 nti inch. Tsis tas li ntawd, 10 gauge hlau yog 0.1019 nti hauv txoj kab uas hla. Txoj kab uas hla ntawm 10/3 cable yog sib npaug rau txoj kab uas hla ntawm plaub 10 gauge xov hlau, rwb thaiv tsev ntawm cov xov hlau, thiab cov cable sheath.
Txawm li cas los xij, yog tias cov xaim hauv av tsis yog insulated (liab tooj liab hlau), txoj kab uas hla yuav raug txo kom raug.
Nco ntsoov: Txoj kab uas hla ntawm cable yuav txawv nyob ntawm seb cov khoom siv, cov chaw tsim khoom thiab kev rwb thaiv tsev ntawm cov xaim hauv av.
Puas yog 10/3 hnyav hlau txaus rau lub tshuab ziab khaub ncaws?
Rau feem ntau cov tshuab ziab khaub ncaws, 10/3 xaim yog qhov kev xaiv zoo uas lub tshuab ziab khaub ncaws xav tau 30 amps lossis tsawg dua. Yog li, xyuas cov amperage ua ntej txuas lub tshuab ziab khaub ncaws rau 10/3 cable thiab xyuas kom meej tias 220V plaub-pin socket yog npaj txhij.
Tswv yim: Overcurrent tuaj yeem ua rau lub Circuit Court breaker mus thiab qee zaum ua rau hluav taws. Yog li ntawd, ib txwm ua raws li cov lus qhia saum toj no thaum siv 10/3 cable.
Cable voltage poob 10/3
Ua ntej txuas lub 10/3 cable mus rau lub tshuab ziab khaub ncaws, nws yog qhov zoo tshaj plaws los xyuas qhov voltage poob. Xav txog qhov siab tshaj plaws voltage poob ntawm 3%.
Rau ib-theem fais fab mov 120 V, 30 A:
10 AWG xaim muaj peev xwm nqa tau 58 ko taw ntawm tam sim no yam tsis muaj kev txwv tsis pub dhau voltage poob. Sim khaws nws li 50 ko taw.
Rau ib-theem fais fab mov 240 V, 30 A:
10 AWG xaim muaj peev xwm nqa tau 115 ko taw ntawm tam sim no yam tsis muaj kev txwv tsis pub dhau voltage poob. Sim khaws nws li 100 ko taw.
Qhib rau Voltage drop tshuab xam zauv.
Puas tuaj yeem 10/3 xaim khiav hauv av?
Yog, rau kev siv hauv av 10/3 cable yog qhov kev xaiv zoo heev. Txawm li cas los xij, kom khiav 10/3 cable underground, koj yuav xav tau ob yam.
- Cable 10/3uF
- cov kav dej
Ua ntej, yog tias koj tab tom npaj yuav faus cov hlau, koj yuav xav tau ntau txoj kev. Tom qab ntawd yuav 10/3 xaim nrog kev xaiv hauv av. Cov xov hlau no tshwj xeeb tsim los siv hauv av. Feem ntau cov kab hluav taws xob UV raug txiav nrog cov thermoplastic nyuaj. Nov yog ob peb yam tseem ceeb los xav txog thaum faus 10/3 UF hlau.
- Xav txog qhov poob qis. nws yuav tsum qis dua 3%.
- Yog tias koj faus hlau nrog cov kav dej, faus lawv yam tsawg kawg yog 18 nti tob.
- Yog tias koj faus hlau ncaj qha, faus nws tsawg kawg 24 ntiv tes.
Muaj pes tsawg lub qhov (socket) tuaj yeem muab tso rau ntawm 10/3 hlau?
Hlau 10/3 yog ntsuas rau 30 amps. Txawm li cas los xij, raws li NEC, koj tsuas tuaj yeem teeb tsa ib lub 30 amp qhov hluav taws xob rau 30 amp circuit.
Muaj pes tsawg qhov hluav taws xob rau 20 amp Circuit Court?
Raws li NEC, ib qho kev sib txuas yuav tsum raug thauj mus los ntawm 80% lossis tsawg dua. Yog li yog tias peb xav txog qhov no,
Xav tau lub hwj chim ib qhov hluav taws xob =
Yog li ntawd
Number of outputs =
Hauv 20 amp Circuit Court, kaum 1.5 amp qhov hluav taws xob tuaj yeem txuas nrog.
Summing txog
Tsis muaj qhov tsis ntseeg, 10/3 cable yog qhov kev xaiv zoo tshaj plaws rau 30 amp qhov hluav taws xob thiab circuits. Tab sis nco ntsoov, thaum twg koj siv 10/3 cable, ua tib zoo ceev faj. Koj tab tom cuam tshuam nrog cov hluav taws xob tseem ceeb. Yog li ntawd, ib qho miscalculation yuav ua rau muaj kev huam yuaj. (2)
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
- Cov hlau twg kub yog tias ob lub xov hlau yog tib xim
- dawb hlau zoo los yog tsis zoo
