1. Ubuninzi obulinganisiweyo bangoku bebhasi ephambili: ixabiso elilinganisiweyo lelona xesha liphezulu elinokuthi lithwale ibhasi enkulu.
2. Ilinganiswe ixesha elifutshane lokumelana nomgangatho wangoku: inikwe ngumenzi, ingcambu ithetha ixabiso lesikwere lexesha elifutshane lokumelana nangoku ukuba isekethe kwisixhobo esipheleleyo sinokuqhutyelwa ngokukhuselekileyo phantsi kweemeko zovavanyo ezichazwe kwi-8.2.3 yomgangatho wesizwe. GB7251.1-2005 .
3. I-Peak short-time stand current: Ngaphantsi kweemeko zovavanyo ezichaziweyo, umenzi uchaza i-peak current ukuba le sekethi inokumelana ngokwanelisayo.
4. Inqanaba lokukhusela i-Enclosure: ngokwemigangatho ye-IEC60529-1989 enikezelwa yiseti epheleleyo yezixhobo zokuthintela ukudibanisa kunye neendawo eziphilayo, kunye nokuhlaselwa kwezinto eziqinileyo zangaphandle kunye nenqanaba lokungena kwamanzi.Jonga umgangatho we-IEC60529 wecandelo lebakala elithile.
5. Indlela yokuhlukana kwangaphakathi: Ngokomgangatho we-IEC60529-1989, ukwenzela ukukhusela ukhuseleko lomntu, i-switchgear ihlukaniswe ngamacandelo amaninzi ngeendlela ezahlukeneyo.Iimpawu zobugcisa zeentlobo ezahlukeneyo zeekhabhinethi zokusabalalisa zihluke kakhulu, kwaye iiparitha zezobugcisa zeekhabhinethi zokusasazwa kwamanye amazwe zingcono kakhulu kuneebhokisi zokusasazwa kwasekhaya, kodwa akunakuqwalaselwa ukuba iikhabhinethi zokusasazwa kwamanye amazwe kufuneka zibe ngcono kuneekhabhinethi zokusasazwa kwasekhaya.
