I-1. I-voltage kunye neereyithi zangoku: Iintambo ezisetyenziswayo ngemfuno ezihambelana ne-voltage efanayo kunye neereyithingi zangoku ukuqinisekisa ukuba umthwalo usasazwe ngokulinganayo.
2. Uhlobo lwentambo: Iindidi ezahlukeneyo zentambo (umzekelo, iintambo zobhedu kunye ne-Aluminium Cabs) zinokuba nezihloko ezihlukileyo kunye nokunikezelwa kwezakhono, oko kuya kufuneka zihlawulwe xa zisetyenziswa ngokuhambelana.
3. Indlela yonxibelelwano: Indlela yonxibelelwano yentambo kufuneka ihambelane nemigangatho yombane ukuqinisekisa ukunxibelelana okuhle, ukunciphisa ukunganyangeki kunye nokulahleka koqhakamshelwano.
4. Iimpawu zombane: Iimpawu zombane zekhetshi ezifanayo (ezinjengokuthi zithintele, amandla kunye ne-interchection) kufuneka ihambelane nokuphazamiseka okungafunekiyo kwi-elektromagnetic okanye i-voltage yehla.
