• Isampula nokubonisa i-voltage ephumayo, yamanje okukhiphayo, imvamisa yokuphumayo,
ingelosi yesigaba, izinga lokushisa lokusebenza,
isikhathi sokugijima, kanye nesixwayiso sephutha.
• Sesha ngokuzenzakalelayo iphuzu elizwakalayo lapho uqala.
• Isikhathi sokuphendula esisheshayo sokukhetha i-voltage nefrequency.
