N7 IV

Chotsukira cha N7 IV Residual Current Circuit chimapereka ntchito yosinthira yokha ndi dziko lapansi

chitetezo cha kutayikira kwa magetsi. Ndipo chimaperekanso chitetezo chosalunjika kwa wogwiritsa ntchito

kuteteza thupi ku zotsatira zoopsa za magetsi ndipo kumateteza moto womwe wachitika

chifukwa cha vuto la magetsi.
