Rau cov kauv fuse txuas hauv qhov hloov hluav taws xob tsawg, lub zog kab yuav tsum txuas nrog lub davhlau ya nyob nruab nrab ntawm qhov nruab nrab, thiab cov kab thauj khoom yuav tsum txuas nrog lub hau ntswj. Nyob rau hauv txoj kev no, yuav tsis muaj hluav taws xob hluav taws xob thaum thau khoom thiab tawm hauv cov tub ntxhais. Porcelain plug-in fuses yuav tsum muab ntsia ntsug. Lub AC, DC lossis cov khoom siv sib txawv ntawm cov hluav taws xob hauv qhov hluav taws xob tsawg-hloov hluav taws xob tsawg yuav tsum muaj cov cim kom pom tseeb. Hauv lub tshuab hluav taws xob tsawg tsawg rau lub teeb pom kev zoo, lub npov pob zeb rau cov kab nruab nrab (N kab) thiab cov kab thaiv kev tiv thaiv kab (PE kab) yuav tsum tau cais tawm cais. Txoj kab xoom thiab kev tiv thaiv xoom kab yuav tsum txuas nrog lub npav npav, thiab lawv yuav tsum tsis txhob sib dhos thiab yuav tsum muaj tus lej. Thaum cov hlau coj tawm ntawm lub vaj huam sib luag, lub vaj huam sib luag hlau xaim lub qhov yuav tsum du thiab tsis muaj burrs, thiab cov hlau vaj huam sib luag yuav tsum tau nruab nrog lub tes tsho tiv thaiv insulating. Lub plhaub hlau hluav taws xob qis-hloov mus rau cov txee hluav taws xob thaiv yuav tsum muaj kev ntseeg siab (txuas nrog rau xoom).
Qhov saum toj no yog kev qhia ntawm kev siv hluav taws xob tsawg hluav taws xob tsawg hluav taws xob pauv hloov ua qauv sib txuas. Tsuas yog tom qab peb tau to taub qhov hluav taws xob tsawg hluav taws xob txuas hloov pauv kev ua haujlwm peb tuaj yeem mus rau qhov kev sib txuas hluav taws xob tsawg thiab tau txais lub zog hluav taws xob thiab siv nws. Don' t txhawj xeeb txog kev puas tsuaj los ntawm kev sib txuas tsis raug ntawm lub tshuab hluav taws xob tsawg.
