Ko te aratohu whānui ko te whiriwhiri i te au fiusi o te 125% ki te 150% o te au kawenga-katoa noa. Mō ngā ara iahiko me ngā motuka, ngā whakawhiti hiko rānei, whakaarohia te au e tomo mai ana i te wā e tīmata ana kia kore ai te fiusi e pupuhi i te wā e mahi noa ana. Ki te ruarua koe, tirohia ngā aratohu whakaritenga tiaki a te kaihanga taputapu, me utu rānei he miihini hiko whai tohu.

P: Me pēhea taku whakamātautau mēnā kei te pai tonu te fiusi kātereti 5x20mm?
A: Ka taea te whakamātautau i tētahi fiusi kātereti me tētahi mita maha kua whakatakotoria ki te ine haere tonu, ātete rānei. Ka whakaatu tētahi fiusi pai i tētahi pānui ātete iti (he iti iho i te 1 ohm mō tētahi fiusi 5x20mm i te pāmahana rūma). Ka whakaatu tētahi fiusi tuwhera i te ātete mutunga kore (kāore he haere tonu). Kia mahara ko ētahi momo fiusi—ina koa ko ngā fiusi tino tere te mahi me ngā huānga tino angiangi—tērā pea ka whakaatu i tētahi ātete teitei ake ahakoa he pai, engari me rēhita tonu te haere tonu. Ka pakaru tonu tētahi fiusi tuwhera tonu, ā, me whakakapi.
