1. Isilinganiso esiphezulu samanje sebhasi elikhulu: inani elilinganiselwe lomkhawulo wamanje ongathwalwa yibhasi elikhulu.
2. Ilinganiselwe ukumelana nesikhathi samanje: inikezwe umenzi, impande inenani eliyisikwele lesikhathi esifushane sokumelana nesekhethi esisetshenziswa esiphelele singathwalwa ngokuphepha ngaphansi kwezimo zokuhlola ezishiwo ku-8.2.3 wezinga likazwelonke. I-GB7251.1-2005 .
3. Ukuphakama kwesikhathi esifushane kokumelana namanje: Ngaphansi kwezimo zokuhlola ezishiwo, umkhiqizi ucacisa amandla aphezulu le sekethi engamelana nawo ngendlela egculisayo.
4. Izinga lokuvikela indawo evalekile: ngokwezinga le-IEC60529-1989 elihlinzekwe isethi ephelele yamathuluzi ukuvimbela ukuthintana nezingxenye ezibukhoma, kanye nokuhlasela kwezinto eziqinile zangaphandle kanye nezinga lokungena koketshezi.Bona indinganiso ye-IEC60529 yokuhlukaniswa kwebanga elithile.
5. Indlela yokuhlukanisa yangaphakathi: Ngokwendinganiso ye-IEC60529-1989, ukuze kuvikelwe ukuphepha komuntu siqu, i-switchgear ihlukaniswe yaba izingxenye eziningana ngezindlela ezahlukene.Imingcele yezobuchwepheshe yezinhlobo ezahlukene zamakhabhinethi okusabalalisa ahluke kakhulu, futhi imingcele yezobuchwepheshe yamakhabhinethi okusabalalisa kwamanye amazwe angcono ngokuyisisekelo kunamabhokisi okusabalalisa asekhaya, kodwa angeke kucatshangelwe ukuthi amakhabhinethi okusabalalisa kwamanye amazwe kufanele abe ngcono kunamakhabhinethi okusabalalisa ekhaya.
