Kuyini Ukuvikelwa kwe-IEC
Amakilasi Okuvikela e-IEC: I-IEC (Ikhomishana Yomhlaba Wonke Ye-Electrotechnical) iyinhlangano yamazwe ngamazwe ebeka amazinga okuphepha esikhala se-electrotechnology. Izigaba zokufakwayo ze-Class I kanye ne-Class II zibhekisela ekwakhiweni kwangaphakathi nokufakwa kukagesi kokuphakelwa kukagesi. Lezi zindinganiso zenzelwe ukuvikela umsebenzisi ekushayweni kukagesi. Isetshenziswa embonini yokukhiqiza izinto zikagesi ukuhlukanisa phakathi kwezidingo zokuxhunywa komhlaba ovikelayo wamadivayisi.
Ikilasi I: Lezi zixhobo kufanele zibe ne-chassis yazo exhunywe ku-electrical earth (ground) yi-earth conductor. Iphutha entweni ebangela ukuthi ikhondukta ephilayo ithinte ikesi izobangela ukugeleza kwamanje kusikhondatha somhlaba. I-curse kufanele ikhubekise idivayisi yamanje noma i-circuit breaker yamanje eyinsalela, ezonqamula ukunikezwa kukagesi entweni.
Isigaba II: Ikilasi 2 noma into esebenza ngogesi evalwe kabili iklanywe ngendlela yokuthi ayidingi (futhi akumele ibe) ukuxhunywa ngokuphepha emhlabeni kagesi (umhlabathi).
Isigaba III: Idizayinelwe ukuthi ihlinzekwe ngomthombo wamandla we-SELV. I-voltage evela ku-SELV supply iphansi ngokwanele ukuthi ngaphansi kwezimo ezijwayelekile umuntu angathintana nayo ngokuphepha ngaphandle kwengozi yokushaqeka kukagesi. Ezinye izici zokuphepha ezakhelwe ku-Class 1 kanye nezinto zikagesi ze-Class 2 azidingeki.
