Ithebula 17 kanye neThebula 18 le-IEC 60335-1
Kukhona inothi kuthebula 17 kanye nethebula 18 njengokuthi “Kuma-voltage okusebenza kanye ne-gt; 10 V kanye ≤ 630 V, uma i-voltage ingacaciswanga kuthebula, amanani amabanga ahamba phambili angatholwa ngokufaka phakathi.”. Uma i-voltage yokusebenza ingelona inani elisohlwini lwetafula, ngakho-ke ngokuvamile sidinga ukubala ukuze sithole inani elilinganiselwe, ukuze kube lula, ngilungise ithebula le-excel, abahloli bangabuza ngokuqondile ithebula ukuze bathole inani elihambisanayo lomkhawulo.
