Imodoka nshasha z’inguvu zishobora gushaja muhira. Gukoresha imodoka zikoresha umuyagankuba mu rugo ntizirenga amategeko y’amashanyarazi, ariko umuyagankuba wo mu rugo usanzwe ni 220V, rero imodoka zikoresha umuyagankuba zishobora gusa gushaja buhoro buhoro, kenshi zifata amasaha arenga umunani kugira ngo zishiremwo neza. Ivyo bituma gushaja bibereye cane gushaja ijoro ryose. Imodoka nyinshi zikoresha umuyagankuba ubu zifise urutonde rwo gushaja rushobora gukoreshwa, ivyo bikaba ari ngirakamaro cane cane mu bice bifise isonga n’izivuye ku giciro c’amashanyarazi. Gusa ushireho igihe co gushaja, ushireko igikoresho co gucapura, hanyuma urindire ko itangura gushaja mw’ijoro igihe ibiciro vy’amashanyarazi biri hasi. Ibintu vyo kwibuka igihe uriko urakoresha imodoka zikoresha umuyagankuba muhira:
1. Kwirinda gukoresha ivyuma biguruka: Ubu buryo, cane cane ku baba ku bibanza vyo hasi, akenshi bikaba birimwo gukoresha ivyuma biguruka. Ubwo buryo bujanye n’ugushiraho umugozi w’amashanyarazi uva ku nzira y’amashanyarazi gushika ku nzira iri hafi y’imodoka, hanyuma ugaca ushiramwo igikoresho co gucapura mu gitereko c’amashanyarazi. Ubwo buryo burateye akaga cane kuko izo nsinga ndende zituma umuntu ashobora guhangana cane, ivyo bikaba bishobora gutuma umuntu ashobora gushuha cane no gutuma umuriro utera cane, ivyo bikaba bitera ubwoba umuyagankuba be n’ibindi biza.
2. Birabujijwe cane gufungura igipfukisho c’imbere igihe uriko urashaza: Gukoresha imodoka y’umuyagankuba i muhira biragenda buhoro, kandi benshi mu bafise imodoka bazokoresha ico gihe kugira ngo bafungure igipfukisho no gusukura inkungugu iri muri iyo nzu. Ivyo birateye akaga cane. Ico kibanza muri rusangi cuzuye - amashanyarazi. Naho hariho uburinzi bw’amazi, iyo hari ingorane, ingaruka zizoba mbi. Ku bw’ivyo, urakeneye kwitwararika igihe uriko urasaba imodoka kugira ngo ukingire umutekano wa nyen’iyo modoka n’abandi.
