Aibhokisi yokusasazwaisebenza ngokufumana igalelo elinye lombane kwaye yahlule ibe ziisekethe ezininzi ezizimeleyo ezinika amandla kwiindawo ezahlukeneyo zesakhiwo. Ngaphakathi,circuit brii-eakersokanye iifusi zisebenza njengezixhobo zokhuseleko, zijonga ukuhamba kwamandla kwisekethe nganye kwaye "zikhubeka" ngokuzenzekelayo ukuze zivale umbane kuloo sekethe ethile ukuba kwenzeka ukuxinana okanye isekethe emfutshane. Oku kuthintela umonakalo, kunciphisa umngcipheko womlilo, kwaye kuvumela ulawulo lombane kwindawo ethile, okwenza ibhokisi yokusasaza ibe yindawo ephakathi, ekhuselayo yenkqubo yombane iphela.

1. Ukufakwa kwamandla

• Umbane ungena kwibhokisi yokuhambisa (ekwabizwa ngokuba yibhodi yokuhambisa okanye iphaneli) usuka kwintambo yokungena yenkonzo ephambili eqhagamshelwe kumthombo wamandla oyintloko wesakhiwo.

2. Ukusasazwa kwiiSekethe

• Ngaphakathi kwebhokisi, umbane oyintloko ongenayo uyadluliselwa kwaye usasazwe kwiisekethe ezahlukeneyo.
• Isekethe nganye ithunyelwa kwindawo ethile okanye kwiseti yezixhobo kwisakhiwo, njengezibane, iindawo zokukhupha umoya, okanye oomatshini.

3. Izixhobo zokukhusela

• Isekethe nganye inesixhobo sokukhusela, ngesiqhelo i-circuit breaker okanye i-fuse.
• Ezi zixhobo zihlala zijonga umbane waloo circuit.

4. Ukhuseleko lokulayishwa kakhulu kunye nokujikeleza okufutshane

• Ukuba isekethe itsala amandla amaninzi (umthwalo omninzi) okanye impazamo ibangela ukunyuka ngequbuliso komsinga (isekethe emfutshane), i-circuit breaker okanye i-fuse iyayibona imeko eyingozi.
• Emva koko isixhobo siya “kukhubeka” okanye “sivuthuze,” siqhawule ngokuzenzekelayo umbane kuloo sekethe ithile.

5. Ulawulo kunye nokuseta kwakhona ngesandla

• Oku kuvala ngokuzenzekelayo kuthintela iingcingo ukuba zingatshisi kakhulu kwaye zibangele umlilo, kukhusela iingcingo kunye nezixhobo ezixhunyiweyo.
• Xa i-circuit breaker iphuka, umsebenzisi angayiphinda ayivule ngesandla ngokuyivula kwakhona iswitshi.

6. Ulawulo oluPhakathi kunye noKhuseleko

• Ibhokisi yokuhambisa umbane isebenza njengendawo yokulawula ephambili yenkqubo yombane, inika indlela ekhuselekileyo necwangcisiweyo yokulawula ukusasazwa kombane kulo lonke isakhiwo.
• Iqinisekisa ukuba umbane wahlulwe ngokufanelekileyo, ithintela umonakalo kwaye igcina inkqubo ikhuselekile kwaye ithembekile.
