Spur Off Ring

[Steve100]

I have a query around installing a socket outlet spur off a final ring circuit in a domestic installation which isn

Making the socket outlet your spuring off and rcd would offer no protection to the cable or new socket it would only protect the equipment plugged in. Putting a rcd socket on end of spur again would only give protection to equipment used. No protection to supply circuit. I would go for rcbo option but I'd test the ring final first to make sure all is well on original wiring so the rcbo will hold!!!

Thread moved. RCD sockets do not protect the cable supplying them, only the accessories plugged into them. Why not just put an RCD in or adjacent to the CU? As it would not be much cost difference to RCD sockets and if you ever have to do further amendments to this circuit you would be creating extra costs for the customer by doing half a job now.

Thanks Guys, I presume, if I wanted to run a spur of the ring to supply an outside fix light, I could install a RCD FCU next to the socket outlet I wanted to run the spur from and then run the cable to the light within the allocated zone and the cable would be protected between the RCD FCU and the light in this example?

Yes that's one way. But for a few quid more you could install an rcbo or adjacent rcd protecting the circuit and if any future work is done its all read to rock and roll

How many socket circuits are there in the property?
