Isiguquli kufanele sigxunyekwe ngokuvikelekile endaweni epholile, neyomile. Xhuma okokufaka okunegethivu kuholela kutheminali yokususa kusiguquli.
Qaphela: Uxhumo olubi lokususa lungenza i-voltage ephumayo ilingane ne-voltage yokufaka! Bese uxhuma okokufaka kanye nefuse kutheminali yokufaka. Kuleli qophelo qiniseka ukuthi i-voltage ephumayo ilungile. Uma kunjalo, ungaxhuma ngokuphephile okokusebenza kutheminali ye-OUT usebenzisa i-fuse. (Inani le-Fuse elilingana nokuphumayo
okwamanje).
Qaphela: Imisinga ingaba phezulu kakhulu. Njalo sebenzisa izintambo ezinobubanzi obanele! Uma ingekho i-fuse yokufaka neyokukhiphayo esetshenziswayo, iwaranti ayisebenzi.
