    I suppose that in say a TN domestic installation where there is good earthing and boning, M.C.B.s will trip off if an exposed-conductive-part becomes live due to a fault. No R.C.D. needed. But there are other situations where perhaps water leaks onto electrical parts, or a pet chews through some flex insulation, or a person touches a live damaged garden appliance flex then an effective swift disconnection is required by an R.C.D.
