| Cov Khoom Siv Loj & Cov Ntaub Ntawv | 6/3 nm - b | Rau 55A circuits | Lub raj kub tubs, subpanels |
Qhov tseem ceeb taw tes: Nm {- b yog qhov zoo rauSab Hauv Tsev Cov Hlau Hluav Taws Xob, tab sis nws yuav tsum tsis txhob siv rauKev faus ncaj qha los yog sab nraum zoov.
Nm {- b vs lwm hom hlau
Txhawm rau pab cov neeg siv khoom zoo dua nkag siab qhov twg nm - b fits nyob rau hauv, ntawm no yog kev sib piv nrog cov hom hlau:
| Hlau Hom | Ib puag ncig ib puag ncig | Nta | Cov Kev Siv Raug Raug |
|---|---|---|---|
| Nm - b | Sab hauv tsev cov chaw qhuav | Kev yuag, yooj yim rau nruab, tsis - nws yog xim hlau sheath | Thaj teeb pom kev zoo & Outlets |

| Thhn / thwn | Conduit Institations | Ib Leeg Qiv, Thaum Tshav Kub Kub & Dej noo | Muaj cov hlau, cov tsev lag luam |
| Xhhw | Damp / siab -} qhov chaw kub | XLPE rwb thaiv tsev, muaj zog tiv thaiv muaj zog | Transformers, hnyav {{0} dute cov khoom siv |
Li cas los xaiv cov xaim xaim?
Thaum xaiv cov xov hluav taws xob, cov tshuab hluav taws xob thiab cov tshaj lij tshwj xeeb yuav tsum xav txog qhov hauv qab no:
Los ntawm kev teeb tsa ib puag ncig
- Sab hauv tsev cov chaw qhuav →Nm - b
- Sab nraum zoov lossis hauv av → UF - b
- Kev lag luam lossis Coduit Installations →.hnhw
Los ntawm Circuit Court Thauj
- Dav Teeb Pom Kev Zoo → 14 AWG
- Chav ua noj / Chav dej nthuav tawm → 12 AWG
- Cov Khoom Siv Hnyav → 10 AWG - 6 AWG
Los ntawm kev nyab xeeb daim ntawv pov thawj
- Ib txwm xaiv cov khoom lag luam nrogUL & Cul ntawv pov thawjTxhawm rau kom ua raws li raws li cov qauv Asmeskas kev nyab xeeb.
Cov Lus Nquag Nug
Q1: Nm {- b zoo ib yam li romex?
- No. Romex yog hom, nm - b yog hom xaim. Coob tus neeg hu rau Romex nm - b yooj yim "romex" tawm ntawm tus cwj pwm.
Q2: Puas yog nm - b yuav siv tawm sab nraud?
- Tsis tau. Nm {{- b yog tsim tsuas yog rau qhuav, nyob sab hauv tsev. Rau sab nraum zoov lossis ncaj pob zeb, siv uf - b lossis thhn / xhhw.
Q3: Dab tsi yog qhov ntau thiab tsawg ntawmNm - b?
- Cov qauv ntau thiab tsawg 14/2, 12/2, 10/2, 6/3, npog 15A rau 55A daim ntawv thov.
Los ntawm kev tsom xam saum toj no, peb tuaj yeem pom tau tiasNm {- b thiab romex tsis zoo ib yam: Nm {{- b yog hom xaim, thaum Romex yog ib qho ntawm cov hom feem ntau lees paub ua nm {1} b cable. Nm {- b yog feem ntau haum rau sab hauv chaw qhuav, thaum lwm hom xws li UK, thiab XHHW tau pom zoo rau sab nraum zoov lossis kev siv sab nraum zoov lossis siv.
