U ka khetha meter ea motlakase joang ka hona joale?
Ho na le litekanyetso tse peli tsa hajoale phanele ea metara e bohlale, joalo ka ha ho bonts'itsoe setšoantšong se ka tlase.The Linyangmetaramatshwao 5(60) A. 5A ke ya motheo ya jwale le 60A ke palo e phahameng ka ho fetisisa ea hona joale.Ha motlakase o feta 60A, o tla tlala mme meter e bohlale e tla cha.Ka hona, ha u khetha meter e bohlale, ka lehlakoreng le leng, ha ea lokela ho ba tlase ho feta ea motheo ea hona joale 'me ka lehlakoreng le leng, ha ea lokela ho ba holimo ho feta tekanyo e phahameng ea hona joale.
