(1) Xyuas seb qhov zoo li qhov ci thiab du, puas yog qhov muag tooj liab tawg, seb qhov kev sib txuas ntawm cov ntsia hlau puas yog xoob, seb cov tooj liab muag puas raug, thiab yog tias nws tsis ua raws li qhov yuav tsum tau ua, nws yuav tsum tsis txhob ua haujlwm. Nws yuav tsum tau kho ua ntej siv;
(2) Xyuas kom tseeb tias lub hwj chim tau raug txiav tawm thiab paub meej tias tsis muaj qhov hluav taws xob ntawm cov khoom ua ntej siv;
(3) Tshawb xyuas seb qhov voltage ntawm cov pas nrig hauv av puas zoo ib yam nrog rau qib voltage ntawm cov khoom siv ua haujlwm;
(4) Thaum dai cov pas nrig hauv av, txuas lub hauv av clamp ua ntej, thiab tom qab ntawd txuas cov hluav taws xob clamp; Thaum tshem tawm cov pas nrig hauv av, cov hlua hluav taws xob yuav tsum tau muab tshem tawm ua ntej raws li cov txheej txheem, thiab tom qab ntawd yuav tsum tau muab tshem tawm cov av clamp;
(5) Qhov kev ncua deb ntawm lub luv luv-circuit grounding hlau ntsia tau rau hauv high-voltage grounding pas nrig thiab cov khoom nyob yuav tsum tsis txhob tsawg tshaj li tus nqi tshiab teev nyob rau hauv "Electric Power Safety Regulations", xav txog lub zog ntawm lub grounding hlau. viav vias;
(6) Txhua pawg ntawm "grounding wires" yuav tsum tsis txhob twist thaum siv. Thaum tsis siv, cov hlau mos tooj liab yuav tsum tau coiled thiab khaws cia hauv chav qhuav.
