IET wiring regulations and gn3 very grey sometimes. In a dwelling, sockets that may be used outdoors should really have extra protection, ie. rcd protection at 30 mA or less. How many times do you go to a job and while you’re working there, they’re power washing or trimming the hedge/lawn? I’ve been to jobs where they’ve cut through the extension while I’ve been there! Working off scaffolding, plugging in through a window. Straight away they want an rcd. How would it stand in court if you’ve tested a property, and you record a c3 on no rcd protection on sockets, and someone gets injured/killed? We need to be upgrading installations, it maybe just adding a stand alone rcd for 1-2 circuits, and for that cost and the added safety it brings, why not? Landlords are usually after the cheapest option, and there should be no pressure from them to give it a c3. C2 always if possibility of being used outdoors. We’re electricians arguing about a stupid code, consumers normally aren’t electricians and don’t know any better.
