Xa kuziwa kukhuseleko lombane, ukukhetha i-breaker circuit yangoku eshiyekileyo kunye nokusebenza ngokufanelekileyo kubalulekile. Ii-Residual current circuit breakers, ezikwabizwa ngokuba zii-residual current current devices (RCD), zenzelwe ukukhusela kumngcipheko wokothuka kombane kunye nomlilo obangelwa ziziphene zomhlaba. Ukukhetha i-RCD echanekileyo kwisicelo sakho esithile kubalulekile ekuqinisekiseni ukhuseleko lwabantu kunye nepropati.
Isinyathelo sokuqala ekukhetheni i-residual current circuit breaker kukugqiba ukusebenza kwangoku okufunwa yinkqubo yakho yombane. Oku kunokwenziwa ngokuvavanya umthwalo opheleleyo kwisekethe kunye nokumisela ubuninzi bangoku obunokuvuza emhlabeni. Kubalulekile ukuqwalasela ukusebenza okuqhelekileyo kwangoku kunye nayiphi na imisinga yesikhashana enokuthi yenzeke.
Nje ukuba ukusebenza kwangoku kumiselwe, uhlobo olufanelekileyo lwe-RCD lunokukhethwa. Kukho iintlobo ezahlukeneyo ze-RCD ezikhoyo, kubandakanywa uhlobo lwe-AC, uhlobo lwe-A kunye noHlobo lwe-B, uhlobo ngalunye lwenzelwe ukubonelela ngokhuseleko kuhlobo oluthile lwesiphoso. Umzekelo, Uhlobo lwe-AC RCDs lufanelekile kwizicelo zenjongo jikelele, ngelixa Uhlobo lwe-RCDs luyilelwe ukubonelela ngokhuseleko olongezelelweyo kwi-pulsating DC currents. Ii-RCD zodidi lwe-B zibonelela ngelona nqanaba liphezulu lokhuseleko kwaye zifanelekile kwiindawo ezinovakalelo ezifana nezibonelelo zonyango kunye namaziko edatha.
Ukongeza kokukhetha uhlobo oluchanekileyo lwe-RCD, kubalulekile ukuqwalasela uvakalelo lwesixhobo. Ii-RCD zifumaneka kumanqanaba ahlukeneyo ovakalelo, ngokuqhelekileyo ukusuka kwi-10mA ukuya kwi-300mA. Ukukhetha inqanaba lobuntu obufanelekileyo kuxhomekeke kwiimfuno ezithile zenkqubo yombane kunye nenqanaba lokukhusela elifunekayo.
Ukongeza, kufuneka kuqinisekiswe ukuba i-RCD ekhethiweyo ihambelana nemigangatho yokhuseleko olufanelekileyo kunye nemimiselo. Khangela ii-RCD eziqinisekiswe yi-arhente yokuvavanya evunyiweyo kwaye ihlangabezane neemfuno eziyimfuneko zokusebenza kunye nokhuseleko.
Ngamafutshane, ukukhetha i-breaker circuit evuzayo kunye nokusebenza ngokufanelekileyo kubalulekile ekuqinisekiseni ukhuseleko lombane. Ngokumisela ngokuchanekileyo ukusebenza kwangoku, ukukhetha uhlobo olufanelekileyo lwe-RCD kunye novelwano, kunye nokuqinisekisa ukuthotyelwa kwemigangatho yokhuseleko, unokuthintela ngokufanelekileyo ukutshatyalaliswa kunye neengozi zomlilo kwinkqubo yakho yombane.
