I-ACB yoMphuhlisi weSekethe yoMoya

Kuyilo lwezakhiwo zoluntu, i-low-voltageiziphuli zesekethezisetyenziswa kakhulu ekukhuseleni nasekusebenziseni umthwalo omninzi,intambo emfutshane, umbane ogqithisileyo, ukulahleka kombane, umbane ongaphantsi kwamandla awo, umhlaba ophantsi, ukuvuza,ukutshintsha ngokuzenzekelayo kwezixhobo zombane ezimbini, kunye nokuqala rhoqo kweemoto. Imigaqo Ukongeza ekuthobeleni imigaqo esisiseko efana neempawu zemeko-bume yokusetyenziswa kweizixhobo zombane ezisebenzisa umbane ophantsi(jonga iNcwadi yoYilo loSasazo lwaMandla oMzi-mveliso noLwakhiwo), le miqathango ilandelayo kufuneka iqwalaselwe:
1) I-voltage elinganisiweyo yeumephuli wojikelezoakufanele kube ngaphantsi kwevolthi elinganisiweyo yomgca;
2) Umlinganiselo wamandla ombane olinganisiweyoumephuli wojikelezokwaye umlinganiselo wamandla okukhululwa kombane ogqithisileyo awukho ngaphantsi komlinganiselo wamandla omgca obaliweyo;
3) Umthamo wokuqhekeka kwesekethe emfutshane olinganisiweyoumephuli wojikelezoayingaphantsi komlinganiselo ophezulu we-short-circuit kumgca;
4) Ukusasazwa okukhethiweyoiziphuli zesekethekufuneka kuqwalaselwe amandla okuvala i-short-delay-circuit kunye nokulungelelaniswa phakathi kwamanqanaba okukhusela ukulibaziseka;
5) I-voltage elinganisiweyo yokukhululwa kwe-undervoltage ye-circuit breaker ilingana ne-voltage elinganisiweyo yomgca;
6) Xa isetyenziselwa ukukhusela i-motor, umsinga wokuqala we-motor kufuneka uqwalaselwe ekukhetheni i-circuit breaker kwaye akufuneki usebenze ngexesha lokuqala; ukuze ufumane ubalo loyilo, jonga “Incwadi Yoyilo Lokusasazwa Kwamandla Ezemizi-mveliso Nawoluntu”;
7) Ukukhethwa kweiziphuli zeseketheKufuneka kuqwalaselwe nokulungelelaniswa okukhethiweyo kwee-circuit breakers kunye nee-circuit breakers,iziphuli zesekethekunye neefusi.
