Ama-circuit breaker kumishini kagesi ene-voltage ephansi abekwa ngendlela efanele ngaphakathi kwebhodi lokushintsha noma iphaneli elivalwe ngensimbi, lapho i-breaker eyinhloko ivame ukuba maphakathi ukuze kulinganiswe umthwalo, kanye nama-breaker ngamanye ahlelwe ngokuqondile futhi ahlukaniswe ukuze kuvikelwe ama-circuit athile njengokukhanyisa noma izindawo zokuphuma. Indawo yesibambo se-breaker ikhombisa isimo sayo, kanti elithi “phezulu” livame ukusho ukuthi “kuvuliwe” kanye nokuthi “phansi” lisho ukuthi “kuvaliwe,” yize indawo esakhiweni ivame ukuba yindawo ephakathi noma efinyelelekayo njengegaraji, i-basement, noma ikhabethe le-utility.
Ukubekwa kwephaneli kanye nebhodi lokushintsha

I-breaker eyinhloko:
Kuma-switchboard amakhulu, i-main circuit breaker ibekwa kahle kukholomu ephakathi ukuze isabalalise ugesi ngokulinganayo emagatsheni kuzo zombili izinhlangothi, okunganciphisa usayizi odingekayo wama-busbar amakhulu.

Ama-breaker ngamanye:
Ngaphakathi kwebhodi lokushintsha, ama-breaker ngamanye avame ukuhlelwa ngokuqondile ezindaweni ezihlukene. I-breaker ngayinye ingeyesekethe ethile, njengokukhanyisa noma izindawo zikagesi.

Ukufinyeleleka:
Ibhodi lokushintshana ngokwalo livame ukutholakala endaweni enabantu abaningi esakhiweni, njengegaraji, isisekelo, noma ikhabethe likagesi.
Isikhundla nesimo se-breaker

Khanyisa cisha:
Indawo yesibambo ikhombisa isimo se-breaker. Ezimweni eziningi, uma isibambo sisesimweni “sokuphezulu”, isekethe ivuliwe. Uma sisesimweni “sokuphansi”, isekethe ivaliwe.

Ukhubekile:
Uma i-breaker ikhubekile ngenxa yephutha, isibambo singase sibe sesimweni esiphakathi nendawo. Ukuze usisethe kabusha, kufanele uqale uhambise isibambo endaweni "yokuvala" (phansi) ngokuphelele ngaphambi kokusibuyisela ku-"vula" (phezulu).
