When an electrician must be called out, this localised fault can be resolved faster (and therefore cheaper) in contrast with the RCD+MCB's arrangement, which only indicates a fault somewhere within that RCD's set of circuits. This way, a single phase load circuit is connected through three wires viz Phase, In a combination of RCD + RCBO distribution board or single phase 230V split load consumer unit, the load circuits should be connected via three wires i.e. This allows protection in full for all individual circuits and if one trips, all others will still work. Also, dont connect the lighting points and three pin sockets to the same MCB.
