1) Izintambo zekhebula ezisanda kufakwa kufanele zihlolwe ukwamukelwa kanye nezinqubo eziphelele zokwamukela ngaphambi kokuthi ziqale ukusebenza.
2) Ezintamboni eziye zacisha ugesi isikhathi esingaphezu kwesonto kodwa ngaphansi kwenyanga eyodwa, ukumelana kwazo nokufaka ugesi kufanele kulinganiswe nge-megohmmeter ngaphambi kokuba ziphinde zikhishwe. Ukumelana ne-insulation akumele kwehle ngo-30% uma kuqhathaniswa nerekhodi lokuhlola langaphambilini (ngezinga lokushisa elifanayo). Uma kungenjalo, ukuhlolwa kwe-DC ukumelana ne-voltage kufanele kwenziwe. Ezintamboni eziye zanqamuka ugesi isikhathi esingaphezu kwenyanga eyodwa kodwa ngaphansi konyaka owodwa, ukuhlolwa kwe-DC ukumelana nogesi kufanele kwenziwe engxenyeni yevolthi yokuhlola yokuvimbela.
3) Kumakhebuli ane-amatheminali kabusha, izixhumi eziphakathi nendawo, noma izixhumi ezimaphakathi ezisanda kufakwa, indawo yesigaba kufanele iqinisekiswe, ukumelana nokufakwa kwe-insulation kumele kukalwe nge-megohmmeter, futhi ukuhlolwa kwe-voltage ye-withstand kufanele kwenziwe. Kuphela ngemva kokuba zonke izivivinyo seziphumelele lapho izintambo zingavunyelwa ukuthi ziqalise ukusebenza.
