Farqiga u dhexeeya MCB, RCCB, iyo RCBO

1.McB (MIat 'jajabkii jajaban): Hawsha xudunta ayaa ah mid xad dhaaf ah oo ilaalin-gaaban, oo u dhaqma sidii "fiyuus oo casriyeysan" oo loogu talagalay wareegga guryaha, kaas oo kaliya ka gooya qulqulka aan caadiga ahayn ee aan laga walwalaynin naxdinta korantada.

2.RCCB (hadhaaga hadhaaga hadda jira): Hawsha aasaasiga ah waa daadashada hadda jirta. Waxay safar qaadataa markii la ogaanayo shoog koronto oo bini'aadamka ah (qulqulka hadda jira ee dhulka) laakiin kama hortaga culeyska xad dhaafka ah ama wareejinta gaagaaban.

3.RCBO (haraaga ka-goynta hadda jirta oo leh ilaalin xad dhaaf ah): Waxay isku daraysaa howlaha McB (jahwareerka wareega ee 'Mindica' iyo RCCB (harsan wareejinta wareega hadda jira), oo bixiya kahortag sedex ah oo kahortaga culeyska, wareegga gaagaaban, iyo baxsiga hadda, oo ka dhigaya kuwa ugu dhawaanshaha waxqabadka.

Si fudud u dhig, MCB waxay ka hortagtaa "guuldaradii wareegga," halka waardiye RCCB ka dhanka ah "shoog koronto." RCbo waxay ka difaacdaa labadaba.
