Qhov no tswj thiab tiv thaiv txhua lub voj voog, kom ntseeg tau tias thaum muaj hluav taws xob tsis ua haujlwm lossis muaj hluav taws xob ntau dhau, tsuas yog lub voj voog uas cuam tshuam xwb thiaj li raug cuam tshuam, thaum lwm yam ntawm lub kaw lus tseem ua haujlwm.
Ib qho ntawm cov haujlwm tseem ceeb ntawm lub thawv faib khoom yog los muab ib txoj hauv kev los cais thiab txiav cov hluav taws xob ntawm ib lub voj voog tshwj xeeb rau kev kho lossis thaum muaj xwm txheej ceev. Qhov no txhim kho kev nyab xeeb ntawm cov neeg ua haujlwm kho thiab tso cai rau cov voj voog tsis zoo kom raug cais tawm sai thiab yooj yim kom tiv thaiv kev phom sij.
Cov thawv faib khoom muaj ntau qhov loj thiab qauv kom tau raws li qhov xav tau ntawm ntau yam kev siv. Lawv muaj txij li cov vaj huam sib luag me me nrog ob peb lub tshuab hluav taws xob mus rau cov thawv faib khoom lag luam loj nrog ntau lub vaj huam sib luag thiab cov xov hlau nyuaj. Kev xaiv lub thawv faib khoom nyob ntawm cov yam xws li qhov loj ntawm lub tsev, tus lej ntawm cov voj voog xav tau, thiab cov kev xav tau hluav taws xob tshwj xeeb.
Ntxiv rau lawv txoj haujlwm tseem ceeb ntawm kev faib hluav taws xob, cov thawv faib hluav taws xob niaj hnub no feem ntau muaj cov yam ntxwv siab heev xws li kev tiv thaiv hluav taws xob ntau dhau, cov khoom siv hluav taws xob hauv av (GFCI), thiab cov khoom siv hluav taws xob arc fault circuit interrupters (AFCI) los txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm cov kab ke hluav taws xob. Cov yam ntxwv no pab tiv thaiv kev nce hluav taws xob, kev puas tsuaj hauv av, thiab kev puas tsuaj arc, txo qhov kev pheej hmoo ntawm hluav taws xob thiab ua kom muaj kev nyab xeeb ntawm cov neeg nyob hauv.
Kev teeb tsa thiab kev saib xyuas cov thawv faib khoom kom raug yog qhov tseem ceeb heev rau kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov tshuab hluav taws xob. Nws yog ib qho tseem ceeb uas cov thawv hluav taws xob raug teeb tsa los ntawm tus kws hluav taws xob tsim nyog raws li cov cai thiab cov cai hauv zos. Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas kuj tseem ceeb rau kev txheeb xyuas thiab daws txhua yam teeb meem uas yuav tshwm sim dhau sijhawm.
Thaum xaiv lub thawv faib khoom, nws yog ib qho tseem ceeb uas yuav tsum xav txog tej yam xws li lub peev xwm ntawm lub thawv, hom thiab tus naj npawb ntawm cov voj voog uas nws tuaj yeem ua tau, thiab cov kev cai tshwj xeeb ntawm lub kaw lus hluav taws xob. Nws tseem yog ib qho tseem ceeb kom ntseeg tau tias cov thawv faib khoom hluav taws xob los ntawm cov chaw tsim khoom muaj npe nrov thiab ua tau raws li cov qauv kev nyab xeeb thiab kev ua tau zoo tsim nyog.
Hauv kev xaus lus, cov thawv faib khoom yog cov khoom tseem ceeb hauv cov kab ke hluav taws xob, ua lub hauv paus rau kev faib hluav taws xob rau ntau lub voj voog thaum muab kev tiv thaiv thiab kev tswj hwm. Los ntawm kev xaiv lub thawv faib khoom kom raug thiab xyuas kom meej tias kev teeb tsa thiab kev saib xyuas kom zoo, nws muaj peev xwm tsim cov kab ke faib hluav taws xob muaj kev nyab xeeb thiab txhim khu kev qha rau kev siv hauv tsev, kev lag luam thiab kev lag luam.
