1. Isilinganiso esiphezulu samanje sebhasi elikhulu phakathi ibhokisi lokusabalalisa : inani elilinganiselwe lomkhawulo wamanje ongathwalwa yibhasi enkulu.
2. Ilinganiselwe ukumelana nesikhathi samanje: inikezwe umenzi, impande isho inani eliyisikwele lesikhathi esifushane sokumelana namanje lapho isekethe esisetshenziswa esiphelele singathwalwa ngokuphepha ngaphansi kwezimo zokuhlola ezishiwo ku-8.2.3 wezinga likazwelonke le-GB7251.1-2005 .
3. Ukuphakama kwesikhathi esifushane kokumelana namanje: Ngaphansi kwezimo zokuhlola ezishiwo, umkhiqizi ucacisa amandla amanje aphezulu le sekethi engamelana nawo ngendlela egculisayo.
4. Izinga lokuvikela indawo ebiyelwe: 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. Ibhokisi lokusabalalisa Indlela yokuhlukanisa yangaphakathi: Ngokwezinga le-IEC60529-1989, ukuze kuvikelwe ukuphepha komuntu siqu, i-switchgear ihlukaniswe yaba amakhompathimenti amaningana ngezindlela ezihlukene.
