Ntau npaum li cas xaim tawm hauv qhov hluav taws xob?
Txheem
Hauv kab lus no, kuv yuav qhia koj tias pes tsawg cov xov hlau tawm hauv qhov hluav taws xob.
Ntau cov xaim hauv qhov hluav taws xob ntau dhau tuaj yeem ua rau cov xov hlau kub dhau, uas tuaj yeem ua rau hluav taws kub. Cov xaim luv luv tuaj yeem tawg cov xov hlau no. Puas muaj lub ntsiab lus golden rau txhua qhov no? Yog lawm, koj tuaj yeem zam cov xwm txheej saum toj no los ntawm kev ua raws li NEC code. Yog nej tsis paub ces kuv yuav qhia nej ntxiv hauv qab no.
Feem ntau, koj yuav tsum tawm tsawg kawg 6 ntiv tes ntawm cov hlau hauv lub thawv sib txuas. Thaum cov hlau nyob ntawm kab kab rov tav, nws yuav tsum protrude 3 ntiv tes tawm ntawm lub qhov thiab lwm 3 ntiv tes yuav tsum nyob hauv lub thawv.
Kuv mam li mus rau hauv ntau yam hauv qab no.
Qhov zoo tagnrho ntev ntawm cov xaim tawm hauv qhov hluav taws xob
Qhov tseeb ntev ntawm cov hluav taws xob xaim yog qhov tseem ceeb rau kev nyab xeeb ntawm cov xov hlau.
Piv txwv li, cov xov hlau luv luv tuaj yeem tawg vim kev ncab. Yog tias lub qhov hluav taws xob nyob hauv thaj chaw uas muaj qhov kub tsis zoo, cov xov hlau luv luv yuav yog qhov teeb meem rau koj. Yog li, xav txog tag nrho cov no ua ntej xaim hluav taws xob qhov hluav taws xob.
NEC code rau hlau slack hauv lub thawv
Raws li NEC, koj yuav tsum tawm tsawg kawg 6 ntiv tes ntawm cov hlau.
Tus nqi no nyob ntawm ib yam; qhov hluav taws xob lub thawv qhov tob. Feem ntau cov qhov hluav taws xob yog 3 mus rau 3.5 nti tob. Yog li tawm tsawg kawg 6 ntiv tes yog qhov kev xaiv zoo tshaj plaws. Qhov no yuav muab rau koj 3 ntiv tes los ntawm qhib lub thawv. Qhov seem 3 ntiv tes yuav nyob hauv lub thawv, piv txwv tias koj tawm tag nrho ntawm 6 ntiv tes.
Txawm li cas los xij, tawm hauv 6-8 ntiv tes ntawm cov xaim ntev yog qhov kev xaiv yooj yim tshaj plaws yog tias koj siv lub qhov hluav taws xob sib sib zog nqus. Tawm 8 "rau 4" qhov sib sib zog nqus tawm lub thawv.
Nco ntsoov txog: Thaum siv cov qhov (socket) hlau, nco ntsoov tias lub qhov (socket) hauv av. Ua li no, siv insulated ntsuab hlau los yog liab qab tooj liab hlau.
Kuv tuaj yeem tawm ntau npaum li cas hauv kuv lub vaj huam sib luag hluav taws xob?
Tso cov hlau txuas ntxiv rau hauv vaj huam sib luag hluav taws xob rau yav tom ntej tsis yog lub tswv yim phem. Tab sis ntau npaum li cas?
Tso cov hlau ntxiv kom txaus thiab tso rau ntawm ntug ntawm lub vaj huam sib luag.
Tawm ntau cov xov hlau hauv lub vaj huam sib luag tuaj yeem ua rau muaj cua sov. Qhov teeb meem overheating no tsuas yog cuam tshuam nrog cov xaim nqa mus tas li. Muaj ntau cov kab hluav taws xob tsis zoo hauv lub vaj huam sib luag hluav taws xob, xws li cov xaim hauv av. Yog li, koj raug tso cai tawm ntawm cov xov hlau hauv av, tab sis tsis txhob tawm ntau dhau. Qhov no yuav ua rau koj lub vaj huam sib luag hluav taws xob puas.
Muaj cov lej rau cov lus nug no. Koj tuaj yeem pom lawv hauv NEC cov lej hauv qab no.
- 15(B)(3)(a)
- 16
- 20 (A) Av
Nco ntsoov txog: Koj tuaj yeem ib txwm splice xov hlau thaum xav tau ntau dua.
Cov Lus Qhia Txog Kev Nyab Xeeb Hluav Taws Xob
Peb tsis tuaj yeem tsis quav ntsej txog kev nyab xeeb ntawm cov thawv hluav taws xob thiab cov xov hlau. Yog li, ntawm no yog qee cov lus qhia yuav tsum muaj kev nyab xeeb.
Cov xov hlau luv heev
Cov xov hlau luv luv tuaj yeem tawg lossis ua rau muaj kev sib txuas hluav taws xob tsis zoo. Yog li ntawd, ua raws li qhov tsim nyog ntev.
Khaws cov xov hlau hauv lub thawv
Tag nrho cov kev sib txuas ntawm cov hlau yuav tsum nyob hauv lub thawv hluav taws xob. Cov xov hlau liab qab tuaj yeem ua rau ib tus neeg muaj hluav taws xob poob.
Cov thawv hluav taws xob hauv av
Thaum siv cov thawv hluav taws xob hlau, av lawv kom zoo nrog cov hlau liab qab. Kev sib tsoo cov xov hlau tuaj yeem xa hluav taws xob mus rau lub thawv hlau.
Cov kab ntau dhau
Tsis txhob tso ntau cov xov hlau hauv ib lub thawv sib txuas. Cov hlau tuaj yeem ua kom sov sai heev. Yog li, overheating tuaj yeem ua rau hluav taws xob hluav taws xob.
Siv cov txiv ntseej hlau
Siv cov txiv ntseej hlau rau txhua qhov kev sib txuas hluav taws xob hauv lub thawv hluav taws xob. Cov kauj ruam no yog kev ceev faj zoo heev. Tsis tas li ntawd, nws yuav tiv thaiv cov hlau strands mus rau qhov loj.
Nco ntsoov txog: Thaum ua haujlwm nrog hluav taws xob, ua tib zoo ceev faj kom tiv thaiv koj tus kheej thiab koj tsev neeg. (1)
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
