Ma circuit breaker mu zida zamagetsi zamagetsi zotsika mphamvu amayikidwa mwanzeru mkati mwa switchboard kapena panel yokhala ndi chitsulo, pomwe breaker yayikulu nthawi zambiri imakhala pakati kuti igwirizane ndi katundu, ndipo ma breaker amodzi ndi amodzi amakonzedwa molunjika komanso mozungulira kuti ateteze ma circuit enaake monga magetsi kapena malo otulutsira magetsi. Malo a chogwirira cha breaker amasonyeza momwe chilili, ndipo "mmwamba" nthawi zambiri amatanthauza "pa" ndi "pansi" amatanthauza "kuchoka," ngakhale kuti malo omwe ali mnyumba nthawi zambiri amakhala malo apakati kapena opezeka mosavuta monga garaja, pansi pa nyumba, kapena chipinda chosungiramo zinthu.
Kuyika kwa panel ndi switchboard

Chophwanya chachikulu:
Mu ma switchboard akuluakulu, chosinthira magetsi chachikulu chimayikidwa bwino pakati kuti chigawire magetsi mofanana ku nthambi mbali zonse ziwiri, zomwe zingachepetse kukula kofunikira kwa mabasi akuluakulu.

Zophwanya payekha:
Mkati mwa switchboard, ma breaker amodzi nthawi zambiri amaikidwa moyimirira m'zipinda zosiyana. Chothyola chilichonse chimakhala cha dera linalake, monga magetsi kapena malo otulutsira magetsi.

Kufikika:
Bolodi losinthira nthawi zambiri limakhala pamalo omwe magalimoto ambiri samayenda bwino m'nyumba, monga garaja, pansi pa nyumba, kapena malo osungiramo zinthu zamagetsi.
Udindo ndi mkhalidwe wa wophwanya

Yatsani/Yatsani:
Malo a chogwirira amasonyeza momwe choswera chilili. Nthawi zambiri, chogwirira chikakhala pamalo "apamwamba", dera limakhala loyatsidwa. Likakhala pamalo "apansi", dera limakhala lozimitsidwa.

Wagwetsedwa:
Ngati chopukusira chagunda chifukwa cha vuto, chogwiriracho chingakhale pamalo apakati. Kuti muchikhazikitsenso, choyamba muyenera kusuntha chogwiriracho pamalo a "kuzima" (pansi) musanachibwezeretse ku "kuyambitsa" (mmwamba).
