2. Qhov ntsuas hluav taws xob ntawm lub fuse yuav tsum tau yoog rau cov kab hluav taws xob theem, thiab cov ntsuas tam sim no ntawm lub fuse yuav tsum siab dua lossis sib npaug rau cov ntsuas tam sim no ntawm cov yaj.
3. Qhov ntsuas tam sim no ntawm cov fuses ntawm txhua theem ntawm cov kab yuav tsum tau muab sib xyaw kom haum, thiab cov ntsuas tam sim no ntawm cov yaj ntawm qib dhau los yuav tsum siab dua qhov ntsuas tam sim no ntawm cov yaj ntawm qib tom ntej.
4. Lub yaj ntawm lub fuse yuav tsum tau muab sib xyaw nrog cov yaj raws li qhov xav tau. Nws tsis raug tso cai los ua kom cov yaj ntawm lub siab nyiam lossis hloov cov yaj nrog lwm cov conductors.
