I-RCD yigama elijwayelekile elisetshenziswa emithethweni nasezimithethweni zokwenza, okuhlanganisa i-RCCB, i-RCBO, kanye ne-CBR. Okusho ukuthi, amadivayisi ahlinzeka "ngokuvikela" kwamanje asele, okungukuthi, lapho ugesi osele udlula umkhawulo ochaziwe noma idivayisi icishiwe ngesandla, athola ugesi osele bese "ehlukanisa" isekethe ngogesi. Ngokuphambene ne-RCM (Residual Current Monitor) esetshenziselwa "ukuthola" ugesi osele kodwa engahlinzeki ngokuvikela ugesi osele - bheka amanothi e-Article 411.1 kanye nezindinganiso zomkhiqizo ezibalwe ekupheleni kwe-Article 722.531.3.101
I-RCCB, i-RCBO, kanye ne-CBR zihlinzeka ngesivikelo ngokuhlukanisa ugesi ukuze kuvinjelwe amaphutha asele abangela ukuba imishini ikhubeke noma ivale ngesandla.
I-RCCB (EN6008-1) kumele isetshenziswe kanye ne-OLPD ehlukile, okungukuthi, i-fuse kanye/noma i-MCB kumele isetshenziswe ukuyivikela ekushiseni ngokweqile.
I-RCCB kanye ne-RCBO zinezici ezizinzile futhi zenzelwe ukuthi zisethwe kabusha ngabantu abavamile uma kwenzeka iphutha.
I-CBR (EN60947-2) I-circuit breaker enomsebenzi wokuvikela wamanje osele owakhelwe ngaphakathi, ofanele ukusetshenziswa kwamanje aphezulu >100A.
I-CBR ingaba nezici ezilungisekayo futhi ayikwazi ukusethwa kabusha ngabantu abavamile uma kwenzeka iphutha.
Isigaba 722.531.3.101 sibhekisela naku-EN62423; izidingo ezengeziwe zokuklama ezisebenza ku-RCCB, RCBO kanye ne-CBR zokuthola ugesi osele we-F noma B.
I-RDC-DD (IEC62955) imele idivayisi yokuthola yamanje ye-DC esele*; igama elijwayelekile lochungechunge lwemishini eyenzelwe ukuthola yamanje yephutha le-DC ebushelelezi ezinhlelweni zokushaja ku-Mode 3, futhi isekela ukusetshenziswa kwama-RCD ohlobo A noma ohlobo F kusekethe.
Izinga le-RDC-DD i-IEC 62955 lichaza amafomethi amabili ayisisekelo, i-RDC-MD kanye ne-RDC-PD. Ukuqonda amafomethi ahlukene kuzoqinisekisa ukuthi ngeke uthenge imikhiqizo engasetshenziswa.
I-RDC-PD (idivayisi evikelayo) ihlanganisa ukutholwa kwe-DC okubushelelezi okungu-6 mA kanye nokuvikelwa kwamanje okusele okungu-30 mA A noma F kudivayisi efanayo. Ukuxhumana kwe-RDC-PD kuhlukaniswa ngogesi uma kwenzeka iphutha lamanje elisele.
