Puas yog nm {- b ntub nyob? -}} xov xwm

Nyob rau sab qaum teb Asmeskas hluav taws xob kev lag luam,Nm {- b cable (tsis - nws yog xim hlau sheathed cable, hom b)Puas yog ib qho ntawm cov kev xaiv dav ntau rau cov chaw nyob thiab lub teeb lag luam kev lag luam. Nws yog feem ntau ntsia rau teeb pom kev zoo, receptacles, thiab cov khoom siv hauv tsev neeg.

Txawm li cas los xij, ib txwm nug cov lus nug rau cov neeg ua haujlwm, cov neeg tsim vaj tse, thiab xaus - cov neeg siv yog:"Nm {{{- b ntub nyob? Next} b siv nyob rau hauv ib puag ncig ib puag ncig?"

Lo lus nug no yog qhov tseem ceeb vim tias nws cuam tshuam nrogHluav taws xob kev nyab xeeb, nec ua raws li, thiab ntev - lub sij hawm kev ua tau zooCov. Xaiv lub cable tsis ncaj ncees lawm hom rau ib puag ncig ib puag ncig tuaj yeem ua rau muaj kev nyab xeeb thiab kev ua txhaum cai.

Hauv tsab xov xwm no, peb yuav themlub ntsiab txhais ntawm nm - b, lub tswvyim ntawm ntub dej, lawv siv, sib piv nrog lwm cov khoom siv cable, thiab yuav ua li cas xaiv cov khoom zoo.

Nm {- b sawvTsis - nws yog xim hlau sheathed cable, hom b, tsim tawm hauv qabUL 83 thiab UL 719 cov qauv, thiab ua raws li covNEC (National Electrical Code).

Nws cov kev tsim kho suav nrog:

Tooj liab tus neeg xyuas khoom: Ul {- ua raws, kev coj zoo.
Kev rwb thaiv tsev: PVC cov khoom, nrog cov xim {- coded tus cwj pwm (dub, dawb, ntsuab, thiab lwm yam).
Tsis - nws yog xim hlau: PVC sab nraud tsho, luam tawm nrog qhov loj me, hom, thiab cov ntawv cim pov thawj.

Tsab ntawv"B"qhia tias cov cable yog ntsuas rau90℃(194 Qib F)Hauv cov chaw qhuav, muab nws ntau dua kub tiv thaiv rau cov chaw nyob thiab cov ntawv tso cai ua lag luam sab hauv xws li:
