I-1. Ukunciphisa iBandla lamaNcinci le-Cable: Ukuba ubukhulu bomngxunya wokubekwa akwanelanga, amandla ayo anokukhokelela kwi-voltage eqhelekileyo ye-voltage kwaye unobangela wesixhobo
Ukonakala okanye ukwenzakala komntu.
Okwesibini, ukukhawuleza ukwaluphala kwentambo: Ukuxhathisa kuguquko lobushushu, umswakama, ukuntywila kwemichiza, njl njl.
III. Ingozi yokhuseleko: Ngexesha lolwakhiwo kunye nokulungiswa, ukuba i-inshuler maketer incinci kakhulu, inokubangela ukuba iqondo lobushushu liphezulu kakhulu. Ixesha elide - Ikota ephezulu -} ukusebenza kobushushu kuyakukhawulezisa ukwaluphala kwentambo
Isenokubangela imiphumo emibi efana nemililo.
Okwesine, ukwandisa ubunzima bokulala: Ngexesha lenkqubo yokubeka kwentambo, ukuba i-inshuler maketer inzima kakhulu, iya kukhulisa ububanzi bentambo. Kwelinye icala, ukuba i-inshuler maketer icekeceke, intambo inokuthathwa komonakalo xa iphantsi kwamandla angaphandle.
