I-RCD igama elivamile elisetshenziswa kumithethonqubo namakhodi okusebenza, okuhlanganisa i-RCCB, i-RCBO, ne-CBR. Okusho ukuthi, amadivaysi ahlinzeka "ukuvikela" okusele kwamanje, okungukuthi, lapho amandla asele edlula umkhawulo ochaziwe noma idivayisi ivaliwe ngesandla, ibona umbane osele futhi "uhlukanise" ngogesi isekethe. Ngokuphambene ne-RCM (I-Residual Current Monitor) esetshenziselwa “ukubona” insalela yamanje kodwa enganikezi ukuvikelwa kwamanje okuyinsalela-bona amanothi ku-Athikili 411.1 kanye nezindinganiso zomkhiqizo ezisohlwini olusekupheleni kwe-Athikili 722.531.3.101
I-RCCB, i-RCBO, ne-CBR zihlinzeka ngokuvikeleka ngokuhlukanisa ukunikezwa kwamandla ukuze kuvinjelwe amaphutha amanje ayinsalela abangela ukuthi okokusebenza kukhubeke noma kuvalwe ngesandla.
I-RCCB (EN6008-1) kufanele isetshenziswe ngokuhambisana ne-OLPD ehlukile, okungukuthi, i-fuse kanye/noma i-MCB kufanele isetshenziselwe ukuyivikela ekudluleleni kwesikhathi.
I-RCCB ne-RCBO zinezici ezigxilile futhi zenzelwe ukusethwa kabusha abantu abavamile uma kwenzeka iphutha.
I-CBR (EN60947-2) Isinqamuli sesekhethi esinomsebenzi wokuvikela wamanje owakhelwe ngaphakathi, ofanele izinhlelo zokusebenza zamanje eziphakeme >100A.
I-CBR ingaba nezici ezilungisekayo futhi ayikwazi ukusethwa kabusha abantu abajwayelekile uma kwenzeka iphutha.
Isigaba 722.531.3.101 siphinde sibhekisele ku-EN62423; izimfuneko ezengeziwe zedizayini ezisebenza ku-RCCB, RCBO ne-CBR ukuze kutholwe u-F noma u-B wamanje oyinsalela.
I-RDC-DD (IEC62955) imele idivayisi esele ye-DC yokuthola idatha*; igama elivamile lochungechunge lwezisetshenziswa eziklanyelwe ukuthola iphutha le-DC elibushelelezi ekushajeni izinhlelo zokusebenza ku-Mode 3, futhi lisekela ukusetshenziswa kohlobo A noma uhlobo F RCDs kusekethe.
I-RDC-DD ejwayelekile IEC 62955 icacisa amafomethi amabili ayisisekelo, i-RDC-MD ne-RDC-PD. Ukuqonda amafomethi ahlukene kuzoqinisekisa ukuthi ngeke uthenge imikhiqizo engeke isetshenziswe.
I-RDC-PD (idivayisi yokuvikela) ihlanganisa ukutholwa kwe-DC okubushelelezi okungu-6 mA kanye nokuvikelwa kwamanje okuyinsalela okungu-30 mA noma F kudivayisi efanayo. Oxhumana naye we-RDC-PD uhlukaniswa ngogesi uma kwenzeka kuba nephutha lamanje.
