Kev teeb tsa ua tiav ntawm qis-voltage fais fab faib khoom yuav tsum tau ua los ntawm cov kws tshaj lij. Ua ntej kev teeb tsa, cov cuab yeej yuav tsum tau kuaj xyuas kom ntseeg tau tias nws nyob hauv qhov zoo thiab tag nrho cov khoom muaj nyob. Thaum lub sij hawm lub installation txheej txheem, nws yog ib qho tseem ceeb kom paub tseeb tias lub txee yog ruaj khov anchored, zoo grounded, thiab tag nrho cov busbar kev twb kev txuas yog ruaj khov. Lub sijhawm ua haujlwm yuav tsum muaj cov kauj ruam-los ntawm-qhia kev txheeb xyuas ntau yam haujlwm- suav nrog kev qhib thiab kaw kev ua haujlwm ntawm Circuit Court breakers thiab kev teeb tsa ntawm cov cuab yeej tiv thaiv teeb tsa- kom paub meej tias cov cuab yeej ua haujlwm raug thaum muab tso rau hauv kev pabcuam.
Kev saib xyuas tsis tu ncua yog ib qho kev ntsuas tseem ceeb rau kev ua kom lub sij hawm ntev -, kev ua haujlwm ruaj khov ntawm qis -voltage fais fab faib khoom. Cov txheej txheem tu feem ntau suav nrog kev ntxuav cov plua plav tawm ntawm lub txee sab hauv, tshuaj xyuas cov kev sib txuas ntawm cov busbar kom xoob, thiab kuaj kev ua haujlwm ntawm cov khoom siv tiv thaiv. Yog tias cov khoom puas lossis cov hnub nyoog raug txheeb xyuas, lawv yuav tsum tau hloov tam sim ntawd. Nws raug nquahu kom tsim kom muaj lub sijhawm saib xyuas kom ntxaws thiab sau cov lus qhia tshwj xeeb ntawm txhua qhov kev saib xyuas kom pab txhawb kev taug qab thiab kev tswj xyuas tom ntej.
