Njengezisetshenziswa eziyinhloko emkhakheni wokushaja imoto kagesi, izinqwaba zokushaja ze-DC zisekelwe kumgomo wokuguqula kahle amandla wamanje (AC) ashintshashintshayo asuke kugridi abe amandla e-DC, anikezwa ngokuqondile amabhethri emoto kagesi, eqaphela ukushaja okusheshayo. Lobu buchwepheshe abenzi nje kuphela inqubo yokushaja ibe lula, kodwa futhi buthuthukisa ngokuphawulekayo ukusebenza kahle kokushaja, okuwumfutho obalulekile wokushayela ukuze kwandiswe izimoto ezisebenza ngogesi. Inzuzo yezinqwaba zokushaja ze-DC ilele emandleni azo okushaja asebenza kahle, angafinyeza kakhulu isikhathi sokushaja futhi ahlangabezane nesidingo somsebenzisi sokugcwaliswa kabusha ngokushesha. Ngesikhathi esifanayo, izinga layo eliphezulu lobuhlakani likwenza kube lula kubasebenzisi ukuthi basebenze futhi baqaphe, okuthuthukisa ukunethezeka nokuphepha kokushaja. Ngaphezu kwalokho, ukusetshenziswa okubanzi kwezinqwaba zokushaja kwe-DC nakho kusiza ukukhuthaza ukwenziwa ngcono kwengqalasizinda yezimoto zikagesi kanye nokuduma kokuhamba okuluhlaza.
