Ama-Residual current breakers (ama-RCCB)ziyingxenye ebalulekile yezinhlelo zikagesi zesimanje. Zenzelwe ukuvikela abantu nempahla ngokuthola ukungalingani kwamanje kanye nokunqamula ugesi uma kwenzeka iphutha. Ama-RCCB anikeza izinga eliphezulu lokuphepha futhi adlala indima ebalulekile ekuvimbeleni ukusha kukagesi kanye nemililo kagesi.
I-RCCBivame ukusetshenziswa ezakhiweni zokuhlala nezebhizinisi. Zifakwa ebhodini lokushintsha futhi zixhunywe ngokulandelana nesekethe ezivikelayo. Uma kwenzeka ukungalingani, njengalapho umuntu ethinta ucingo oluphilayo ngengozi, ugesi ogeleza ngezintambo zesigaba kanye nezintambo ezingathathi hlangothi uzohluka. I-RCCB ithola lokhu kungalingani bese ikhubeka ngokushesha, inqamule ukunikezwa kwamandla.
Enye yezinzuzo eziyinhloko ze-RCCB yikhono layo lokubona amaphutha omhlaba aqondile nangaqondile. Amaphutha aqondile ayenzeka lapho umuntu ethintana ngqo nezintambo eziphilayo, kanti amaphutha angaqondile ayenzeka lapho idivayisi noma imishini exhunywe ohlelweni lukagesi yehluleka. Kungakhathaliseki ukuthi hlobo luni lwephutha, i-RCCB ithola futhi inqamule ugesi, inciphisa ingozi yokushaqeka kukagesi noma umlilo.
I-RCCB yenzelwe ukuphendula ngokushesha emaphutheni, iqinisekise ukuthi ugesi unqanyuliwe ngaphambi kokuba kwenzeke noma yimuphi umonakalo. Ngokuvamile bayakhubeka ngaphakathi kwama-millisecond, okuhlinzeka ngokuvikelwa okusheshayo. Lesi sikhathi sokuphendula okusheshayo sibalulekile ekuvimbeleni ukulimala okukhulu noma ukulimala kwemishini kagesi.
Esinye isici esibalulekile sama-RCCB ukuthi asengozini yokuvuza okuncane. Uma kwenzeka iphutha, ngisho nomsinga omncane wokuvuza ungase ubonise ingozi engaba khona. I-RCCB yenzelwe ukuthola la mandla aphansi futhi iqinisekise ukunqanyulwa ngokushesha kokunikezwa kwamandla kagesi, ukuvimbela ukwanda okuqhubekayo kwephutha.
Ukuqinisekisa ukusebenza kwayo kahle, ama-RCCB adinga ukuhlolwa nokugcinwa njalo. Ukuhlolwa kufanele kwenziwe njalo ukuqinisekisa ukusebenza kahle kanye nokuzwela. Ngaphezu kwalokho, kubalulekile ukufaka ama-RCCB ahambisana nezindinganiso zokuphepha ezifanele kanye nemithethonqubo ukuqinisekisa ukuthembeka kwawo.
Kubalulekile ukuqaphela ukuthi ama-RCCB awathathi indawo yesistimu efanele yokusekela nokubopha. Ukusekela nokubopha kunikeza ungqimba olwengeziwe lokuphepha futhi kudlala indima ebalulekile ekuqondiseni amaphutha kude nabantu kanye nempahla. I-RCCB yakhelwe ukuhambisana nalezi zinhlelo futhi inikeze ungqimba olwengeziwe lokuvikela.
Ngamafuphi, i-RCCB iyingxenye ebalulekile yesistimu kagesi futhi iqinisekisa ukuphepha kwabantu nempahla. Ikhono labo lokubona amaphutha, ukuphendula ngokushesha, nokunqamula ugesi kubenza babe usizo kakhulu ekuvimbeleni ukusha kukagesi kanye nemililo kagesi. Ukulungiswa nokuhlolwa njalo kuyadingeka ukuqinisekisa ukusebenza kahle. Uma isetshenziswa kanye nohlelo olufanele lokufaka isisekelo kanye nokubopha, i-RCCB inikeza ikhambi eliphelele lokuphepha lanoma yikuphi ukufakwa kukagesi.
