We recently had our old CU replaced by a new split load RCD one. The split part seems to mean ring main circuits are on RCD side and lighting circuits are on non-RCD side. I understand the reasoning goes "if you've just tripped your RCD, perhaps having touched a live conductor, you don't want to make a dangerous situation worse by having no lights so put them on a non RCD protected circuit".
I was wondering if it is actually a regulation to use a split load or if you wanted, you could have everything RCD protected. I would prefer RCD protection for everything rather than keeping the lights on - where we live there is a power cut about every 2-3 weeks anyway so we're used to the lights going off.
