Xa kuziwa kukhuseleko lombane,izixhobo zokuvala i-circuit breakerzizixhobo ezibalulekileyo zokuthintela ukomeleza amandla ngempazamo.Ezi zixhobo zenzelwe ukuvala ngokukhuselekileyo i-breaker circuit kwi-off position, ukuqinisekisa ukuba ayikwazi ukuvulwa ngelixa umsebenzi wokulondoloza usenziwa.Olunye uhlobo lwesixhobo sokuvala isitshixo sesekethe esiqhele ukusetyenziswa kwimizi-mveliso nakwiseto zorhwebo kukutshixa kwe-breaker oversized.
Ukutshixelwa kwe-breaker oversized luhlobo lwesixhobo sokutshixa esenzelwe ngokukodwa ukuba silingane kwizaphuli zesekethe ezikhulu ezinobukhulu obugqithisileyo okanye obumilo ngokungaqhelekanga.Ezi zaphuli zikhulu zihlala zifumaneka koomatshini abanzima, izixhobo zamashishini, kunye neenkqubo ezinkulu zombane.Ngokungafaniyo nezixhobo eziqhelekileyo zokutshixa i-breaker, ezinokuthi zingangeni ngokukhuselekileyo kwi-breakers oversized, iukutshixelwa kwebreaker enkuluibonelela ngokufanelekileyo nangokukhuselekileyo, ukuqinisekisa ukuba i-breaker ayinakuphazanyiswa okanye ivuliwe ngengozi.
Uyilo lweukutshixelwa kwebreaker enkulungokwesiqhelo ibonakalisa intonga ehlala ixesha elide, ebonakalayo ephezulu enokuthi ibonwe lula ngabasebenzi bolondolozo.I-casing ixhotyiswe ngendlela yokutshixa enokuthi igcinwe nge-padlock, ukukhusela ukufikelela okungagunyaziswanga kwi-breaker.Isixhobo sokutshixa sikwaquka indlela yokuguqula enokuthi ilungelelaniswe lula ukuze ilingane nobukhulu obahlukeneyo bezaphuli ezigqithisileyo, isenze sibe sisisombululo esisebenzisekayo nesisebenzayo kuluhlu olubanzi losetyenziso lwemizi-mveliso nezorhwebo.
Ukusebenzisa i-oversized breaker lockout yindlela elula nesebenzayo yokuphucula ukhuseleko lombane kwindawo yokusebenza.Ngokutshixa ngokukhuselekileyo ngaphandle izaphuli zesekethe ezinkulu, abasebenzi bolondolozo banokuba noxolo lwengqondo besazi ukuba izixhobo abasebenza kuzo azenziwanga amandla kwaye zikhuselekile ukuba zingaphathwa.Oku kunceda ukuthintela iingozi, ukulimala, kunye nomonakalo kwizixhobo, ekugqibeleni kube negalelo kwindawo ekhuselekileyo yokusebenza.
Ukwengeza kwiukutshixelwa kwebreaker enkulu, zikwakho nezinye iindidi zezixhobo zokuvala i-circuit breaker ezifumanekayo, ezifana ne-clamp-on breaker lockout, i-snap-on breaker lockout, kunye nokuvalwa kwe-tie bar.Uhlobo ngalunye lwesixhobo sokutshixa luyilelwe ukuba lulingane iintlobo ezithile zabaphuli beesekethe, kwaye kubalulekile ukukhetha isixhobo esilungileyo sokutshixa kwisaphuli esithile esisetyenziswayo.
Xa ukhetha iisixhobo sokuvala i-breaker circuit, kubalulekile ukuqwalasela ubungakanani kunye nohlobo lwe-breaker, kunye neemfuno ezithile zomsebenzi wokulondoloza owenziweyo.Kukwabalulekile ukuqinisekisa ukuba isixhobo sokutshixa siyahambelana namaqhaga kunye nezinye izixhobo zokhuseleko ezisetyenziswa kwindawo yokusebenza.
Ukuququmbela,izixhobo zokuvala i-circuit breakeridlala indima ebalulekileyo ekuqinisekiseni ukhuseleko lombane kwimizi-mveliso nezorhwebo.Ukusetyenziswa kwe-lockout ye-breaker oversized oversized kunokubonelela ngokhuseleko olongezelelweyo lweziqhekeza ezinkulu, ezingaqhelekanga, ezinceda ukuthintela iingozi kunye nokulimala ngexesha lomsebenzi wokulondoloza.Ngokutyala imali kwizixhobo ezikumgangatho ophezulu zokutshixa kunye nokubonelela ngoqeqesho olubanzi lokhuseleko kubasebenzi, amashishini anokunciphisa umngcipheko weengozi zombane kwaye enze indawo yokusebenza ekhuselekileyo kuye wonke umntu.
