Incazelo emfushane:

Ukusebenza kahle kokuguqulwa okuphezulu, ukuqala okusheshayo;

Isekethe yokuvikela eminingi ye-voltage ephansi, i-voltage eningi, ukulayisha ngokweqile, i-short-circuit, ukushisa ngokweqile njll;

Ifeni Yokupholisa Eyakhelwe Ngaphakathi;

Ikesi le-aluminium elinodisiwe linikeza ukuqina kanye nokushabalalisa ukushisa okuphezulu;

Isicelo esibanzi semikhakha ehlukahlukene njengezimoto, izikebhe, ihhovisi elihambayo, izindlu zomndeni, imisebenzi yokuphuthuma kanye neyangaphandle njll.
