Lub tshuab hluav taws xob cia, raws li cov khoom siv uas hloov thiab khaws cov hluav taws xob hluav taws xob rau hauv lwm hom hluav taws xob, yog qhov tseem ceeb heev. Fuses, raws li cov khoom tseem ceeb tiv thaiv circuits, ua lub luag haujlwm tseem ceeb hauv lub zog cia. Lawv zoo tiv thaiv kev puas tsuaj rau cov khoom siv los ntawm cov khoom siv tam sim no ntau dhau, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm lub zog cia. Tshwj xeeb, daim ntawv thov ntawm fuses hauv lub zog cia tshuab yog qhov tseem ceeb hauv cov hauv qab no:
Ua ntej, lawv tiv thaiv overcharge. Thaum lub sij hawm them nyiaj ntawm lub roj teeb pob hauv lub zog cia, yog tias qhov tam sim no tshaj qhov kev nyab xeeb, lub fuse yuav txiav tawm tam sim ntawd, yog li tsis txhob muaj kev nyab xeeb los ntawm overcharging.
Qhov thib ob, fuses tuaj yeem tiv thaiv kom dhau - tso tawm. Thaum lub pob roj teeb tawm, yog tias qhov tam sim no tshaj qhov chaw nyab xeeb, lub fuse tseem yuav txiav tawm sai sai, kom ntseeg tau tias lub roj teeb pob hluav taws xob tseem nyob hauv qhov tsim nyog thiab lav qhov kev ua haujlwm ruaj khov ntawm lub zog cia.
Tsis tas li ntawd, fuses tseem tuaj yeem ua haujlwm luv luv -circuit faults hauv lub zog cia. Txawm hais tias qhov luv luv Circuit Court yog tshwm sim los ntawm kev laus cov hlua hluav taws xob lossis cov khoom siv puas tsuaj, lub fuse tuaj yeem txiav tawm sai sai thaum muaj kev cuam tshuam luv luv, tiv thaiv kev raug mob hnyav xws li hluav taws kub.
Thaum kawg, fuses kuj tiv thaiv cov khoom siv ntau dhau. Thaum lub sijhawm ua haujlwm ntawm lub zog khaws cia, yog tias cov cuab yeej siv ntau dhau, lub fuse yuav kuaj pom qhov txawv txav ntawm qhov tam sim no thiab tam sim ntawd disconnect Circuit Court, yog li tiv thaiv cov cuab yeej los ntawm kev puas tsuaj lossis kev nyab xeeb.
