Thaum nws los txog rau kev nyab xeeb hluav taws xob, xaiv qhov seem tam sim no Circuit Court breaker nrog qhov tsim nyog kev khiav hauj lwm tam sim no yog qhov tseem ceeb. Residual tam sim no Circuit Court breakers, tseem hu ua residual tam sim no cov cuab yeej (RCD), yog tsim los tiv thaiv kev pheej hmoo ntawm hluav taws xob poob siab thiab hluav taws kub los ntawm av txhaum. Xaiv qhov RCD raug rau koj daim ntawv thov tshwj xeeb yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb ntawm tib neeg thiab khoom.
Thawj kauj ruam hauv kev xaiv qhov tsim nyog seem tam sim no Circuit Court breaker yog txiav txim siab qhov kev khiav hauj lwm tam sim no uas koj xav tau los ntawm koj lub tshuab hluav taws xob. Qhov no tuaj yeem ua tiav los ntawm kev ntsuas tag nrho cov load ntawm lub voj voog thiab txiav txim siab qhov siab tshaj plaws tam sim no uas tuaj yeem xau rau hauv av. Nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov kev khiav hauj lwm tam sim no thiab txhua qhov kev hloov pauv tam sim no uas yuav tshwm sim.
Thaum qhov kev khiav hauj lwm tam sim no tau txiav txim siab, hom RCD tsim nyog tuaj yeem xaiv. Muaj ntau hom RCDs muaj, suav nrog Hom AC, Hom A thiab Hom B, txhua hom yog tsim los tiv thaiv ib hom kev txhaum. Piv txwv li, Hom AC RCDs yog tsim rau cov hom phiaj siv dav dav, thaum Hom A RCDs yog tsim los muab kev tiv thaiv ntxiv tiv thaiv pulsating DC tam sim no. Hom B RCDs muab kev tiv thaiv qib siab tshaj plaws thiab tsim nyog rau ntau qhov chaw muaj kev kub ntxhov xws li cov chaw kho mob thiab cov chaw khaws ntaub ntawv.
Ntxiv rau kev xaiv hom RCD kom raug, nws tseem ceeb heev uas yuav tau xav txog qhov rhiab heev ntawm lub cuab yeej. RCDs muaj nyob rau hauv ntau qib rhiab heev, feem ntau ntawm 10mA txog 300mA. Xaiv qhov tsim nyog rhiab heev yog nyob ntawm cov kev cai tshwj xeeb ntawm lub tshuab hluav taws xob thiab qib kev tiv thaiv yuav tsum tau ua.
Tsis tas li ntawd, nws yuav tsum tau ua kom ntseeg tau tias RCD tau xaiv ua raws li cov qauv kev nyab xeeb thiab cov cai. Nrhiav RCDs uas tau lees paub los ntawm lub chaw kuaj xyuas kev lees paub thiab ua tau raws li qhov tsim nyog ua tau zoo thiab kev nyab xeeb.
Nyob rau hauv luv luv, xaiv ib tug to Circuit Court breaker nrog tsim nyog kev khiav hauj lwm tam sim no yog ib qho tseem ceeb los xyuas kom meej hluav taws xob kev nyab xeeb. Los ntawm kev txiav txim siab qhov kev khiav hauj lwm tam sim no, xaiv qhov tsim nyog RCD hom thiab rhiab heev, thiab ua raws li cov qauv kev nyab xeeb, koj tuaj yeem tiv thaiv kev poob siab thiab hluav taws kub nyhiab hauv koj lub tshuab hluav taws xob.
