Nyob rau hauv cov phiaj xwm hluav taws xob thiab cov xaim npe thaj chaw, kev xaiv ntawm txoj kev cable thiab kev teeb tsa yog qhov tseem ceeb heev. Rau cov tshuab hluav taws xob, cov neeg tsim vaj tse, thiab txawm tias DIY cov tswv tsev, ib qho ntawm feem ntau cov lus nug nug yog:"Nm {- b hlau raug faus rau hauv conduit?"Nkag siab qhov no yog tsis yog tsuas yog hais txog kev ua raws cov hluav taws xob tab sis kuj hais txog kom ua kom muaj kev nyab xeeb ntev thiab ntseeg tau ntawm cov tshuab hluav taws xob.
Kab lus no yuav tshawb txog cov ncauj lus hauv qhov tob {}} b cables {{} Lub ntiaj teb cov piv txwv {}}} kev qhia koj nrog kev qhia meej thiab tshaj lij.
Dab tsi yog nm - b hlau?
Nm {- b (tsis - nws yog hom b) yog ib hom feem ntau ntawm cov hlau hom. Nws cov yam ntxwv tseem ceeb muaj xws li:
- Tsis - nws yog xim hlau sab nraud, making it lightweight and cost-effective.
- Tsim tshwj xeeb rauNyob sab hauv tsev thiab cov ntaub lag luam hluav taws xob ruaj khov.
- Feem ntau ntsuas rauKev thov 600vthiab muaj nyob rau hauv ntau thiab tsawg xws li14/2, 12/2, thiab 10/2.
Txawm li cas los xij, nm - b yognOT Tsim rau kev ua si sab nraum zoov lossis chaw pw ntub dej, uas yog vim li cas cov lus nug ntawm seb nws tuaj yeem faus rau hauv kev conduit tseem ceeb heev.
Nm {- b hlau raug faus rau hauv conduit?
Raws liNEC (National Electrical Code):
- Nm {- b tsis tau ncaj qha faus nyob hauv av, raws li nws cov sheath tsis noo -} lossis corrosion {1} {resistant.
- Nwsyuav ntsia hauv conduit hauv conduit(xws liPVC, EMT, lossis Rigid Hlau Conduit) Los muab kev tiv thaiv kom txaus.
- Yog hais tias ncaj ncaj yog yuav tsum tau,Uf - b cablefeem ntau yog kev xaiv zoo.
👉 Nyob rau hauv luv luv:Nm {- bk xaub tsis tuaj yeem faus ncaj qha rau hauv av tab sis tuaj yeem raug faus kom tsis muaj kev faus kom nyab xeeb.
Tswv yim ua piv txwv
Ntawm no yog ob peb tiag - Cov xwm txheej ntiaj teb los ua piv txwv siv tau zoo:
| Daim Ntawv Thov Kev Thov | Kev siv cov ntawv sau | Pom zoo daws |
|---|---|---|
| Mev teeb pom kev zoo | Cov tswv tsev xav kom nruab vaj teeb vaj tse xav tau av hauv av | Siv PVC Conduit Underground, rub NM - b hlau hauv sab hauv kom tsis txhob ya raws |
| Chaw nres tsheb thauj khoom | Khiav hluav taws xob los ntawm lub tsev loj rau lub tsev nres tsheb khov kho | Xum uf - b cable rau sab xis; Yog tias siv nm - b, conduit yog yuav tsum tau |
| Pas Dej Ntim Tshuab | High - power twj tso kua mis, nthuav tawm rau dej | Yuav tsum siv conduit thiab xav txog dej - tsis kam cable |
| Kev hla hauv av | Cov xov hlau hla lub tsheb lossis qhob pob zeb | Siv cov hlau sib tsoo lossis cov sij hawm 80 PVC conduit, ces khiav nm - b hlau sab hauv |
Cov qauv no tau qhia meej meej tias thaum nm {- b hlau tuaj yeem siv hauv av hauv kev conduit, tusIb puag ncig, thauj khoom, thiab ua raws caiyuav tsum ua tib zoo xav txog.
Qhov zoo thiab cov kev txwv thiab kev txwv ntawm nm - b hauv conduit
Qhov Zoo:
- Tus nqi -}}} Zoo thiab muaj dav.
- Muab kev tiv thaiv zoo thaum nyob hauv conduit.
- Haum rau ntau qhov chaw nyob thiab lub teeb ua lag luam kev lag luam.
Txwv:
- Tsis haum rau kev faus faus lossis tsis tu ncua ib puag ncig.
- Yuav tsum muaj kev teeb tsa kev teeb tsa, nce kev ua haujlwm thiab kev nyuaj.
- Tsawg dua huab cua - tsis kam muab piv rau uf - b lossis thiav.
Kev sib piv nrog lwm hom cable
| Cable Hom | Cov Nta Tseem Ceeb | Cov Ib Zaus Ib puag ncig | Haum rau conduit kev faus neeg? |
|---|---|---|---|
| Nm - b | Kev siv nyob sab hauv tsev, lub teeb yuag, tus nqi tsawg | Qhuav, Sab Hauv Cov Chaw | ✅ Yog (yuav tsum yog nyob rau hauv conduit) |
| UF - b | Noog noo - Thiab corrosion - Tsis kam, tsim rau kev faus neeg | Sab Nraum Zoov & Hauv Qab Av | Kev faus ncaj qha ua tau |
| Hwj chim | Ib leeg tus neeg saib xyuas, cov rwb thaiv tsev ruaj ruaj, yuav tsum tau conduit | Kev lag luam & kev lag luam | ✅ Yuav tsum muaj Conduit |
Los ntawm kev sib piv, nm - b yog nyiaj txiag tab sis txwv. Rau cov ntawv thov sab nraum zoov thiab av,UF - b lossis thhnyog cov kev xaiv zoo dua.
Kev Txiav Txim Siab
Yog tias koj npaj mus faus nm {{- b hlau sab hauv conduit, them sai sai rau cov hauv qab no:
- Xaiv cov conduit kom zoo: PVC cov sij hawm 40 lossis sijhawm 80 yog pom zoo.
- Fig Conduit Ophsing: Tiv thaiv dej los yog ya raws los ntawm nkag mus.
- Zam kev tshaj tawm: Ntau dhau lawm cables nyob rau hauv ib conduit tuaj yeem ua rau overheating overheating.
- Ua raws NEC Codes: Nco ntsoov xyuas cov cai hauv zos ua ntej kev teeb tsa.
- Ua kev soj ntsuam ib txwm muaj: Nco ntsoov ntev - lub sij hawm kev nyab xeeb ntawm cov xaim hluav taws xob.
Ntsiab lus ntawm cov ntawv thov uas haum
- Nyob sab hauv ntsa phab ntsa lossis qab nthab→ nm {- b yog zoo kawg nkaus haum.
- Sab nraum zoov yoj teeb pom kev lossis chaw nres tsheb→ nm {- b yuav tsum nyob sab hauv conduit.
- Noo, ntub dej, lossis ntev - sij hawm underground installationSiv UF - b cable xwb.
✅ Xaus:Nm {{- b hlau tuaj yeem faus rau hauv cov conduit, tab sis nws yuav tsum tsis txhob ua ncaj qha faus hauv av.
