Aidivayisi yokuvala i-circuit breakeriyithuluzi lokuphepha elisetshenziselwa ukuvimbela amandla ngephutha wesekethe ngesikhathi sokulungiswa noma sokulungisa. Kuyingxenye ebalulekile yezinqubo zokuphepha zikagesi ezimbonini, ezentengiselwano nezindawo zokuhlala. Inhloso aukuvala i-circuit breakerukuqinisekisa ukuthi izinto zikagesi zihlala zingenawo amandla ngesikhathi kulungiswa noma kulungiswa, ngaleyo ndlela kuvikelwe abasebenzi engcupheni yokushaqeka ugesi noma ezinye izingozi zikagesi.
Idivayisi yokukhiya imvamisa iyithuluzi elincane, eliphathekayo elingaxhunywa kalula ku-circuit breaker ukuze livinjwe ukuthi lingavuleki. Idizayinelwe ukuthi igxunyekwe ngokuvikelekile kushintsho lwe-circuit breaker, ivimbele ukuthi isetshenziswe. Lokhu kukhiya ngempumelelo i-circuit breaker endaweni evaliwe, iqinisekisa ukuthi isekethe ihlala ingenawo amandla kuze kube yilapho idivayisi yokukhiya ikhishwa.
Kunezinhlobo eziningana zeukuvalwa kwe-circuit breakeretholakalayo, ngayinye yakhelwe uhlobo oluthile lwe-circuit breaker kanye nemishini kagesi. Amanye amadivaysi okukhiya aklanyelwe ukugxunyekwa ekushintsheni kwe-circuit breaker noma ukushintsha kwe-rocker, kuyilapho amanye amadivaysi okukhiya aklanyelwe ukusetshenziswa nama-circuit breaker amacala abunjiwe noma ezinye izisetshenziswa zikagesi ezikhethekile. Ukwengeza, kukhona amadivaysi okukhiya amukela ama-circuit breaker amaningi, okuvumela amasekhethi amaningi ukuthi avalelwe ngaphandle ngesikhathi esisodwa.
Inqubo yokusebenzisa aukuvala i-circuit breakerkuhilela izinyathelo ezimbalwa ezibalulekile zokuqinisekisa ukuqaliswa okufanele. Okokuqala, izisebenzi ezigunyaziwe kufanele zihlonze i-circuit breaker ethile okudingeka ivalelwe ngaphandle. Uma i-circuit breaker isitholakala, idivayisi yokukhiya inamathele ngokuphephile ku-switch, ivimbele ngokuphumelelayo ukuthi ingavuleki. Kubalulekile ukuqinisekisa ukuthi idivayisi yokukhiya ifakwe ngendlela efanele futhi ayikwazi ukususwa kalula noma ukuphazamiseka.
Ngokungeziwe kumadivayisi wokukhiya angaphandle,ukukhiya/ukuphumaizinqubo kumele zisetshenziselwe ukunikeza isibonakaliso esicacile esibonakalayo sokuthi i-circuit breaker ivalelwe ngaphandle futhi akufanele inikezwe amandla. Lokhu ngokuvamile kubandakanya ukunamathisela umaka wokukhiya kudivayisi ekhiyiwe ebonisa isizathu sokuvala ngaphandle, idethi kanye nesikhathi sokuvala ngaphandle, kanye negama lomuntu ogunyaziwe okhiphe. Lokhu kusiza ukuxhumana nabanye abasebenzi ngesimo se-circuit breaker ekhiyiwe futhi kuvimbela imizamo engagunyaziwe yokunika amandla isekethe.
Ukusetshenziswa kweukuvalwa kwe-circuit breakeribuswa imithetho nezimiso zokuphepha, njengalezo ezibekwe yi-US Occupational Safety and Health Administration (OSHA). Le mithetho idinga abaqashi ukuthi basebenzise izinqubo zokuvala ngaphandle/zokuthinta ukuze bavikele abasebenzi ekuvulekeni ngengozi kwemishini noma okokusebenza ngesikhathi sokulungiswa noma kulungiswa. Ukwehluleka ukuthobela le mithetho kungase kuphumele ekujezisweni okubucayi nenhlawulo kubaqashi.
Ekuphetheni,ukuvala i-circuit breakerkuyisinyathelo sokuphepha esibalulekile esiza ukuvikela abasebenzi ezingozini zikagesi ngesikhathi sokulungisa nokulungisa umsebenzi. Ngokukhiya amasekhethi ngokuphumelelayo, lezi zisetshenziswa zivimbela amandla ngengozi futhi zinciphisa ingozi yokushaqeka kukagesi nokunye ukulimala. Abaqashi nabasebenzi kufanele bakuqaphele ukubaluleka kokusebenzisa imishini yokuvala ama-circuit breaker ngokuhambisana nemithetho yezokuphepha ukuze kuqinisekiswe indawo yokusebenza ephephile.
