Spur ?

[HawkEye244]

Quick question, there's a double socket spuring off the ring main in the lounge and I wanted to add another double but do I need to fit a fused socket because there is more than one ?

Yup, the first point on the spur needs to be a fused connection unit, so it would go

Original point on the ring - FCU - Socket - Socket.

Will limit you to 13A on the two sockets, but this is probably fine for most set ups.

Are you sure it's a ring though and not a radial?

Good question, I'll check

Radial socket circuit are more accommodating for unfused spurs, but if it is a ring final circuit you have three options on adding to it.
1) fuse connection unit at the first point that the ring was spurred from, then you can have as many socket from that FCU as you wish, but restricted to 13A demand/load.
2) extend the ring final circuit, as a ring.
3) spur from another socket that is part of the ring and not already a spurred outlet.

Don't forget any newly buried cable and any new sockets, will require to be RCD protected.

Indeed. In fact 'totally accommodating' if one uses the same size cable as for the rest of the radial circuit. They are then not really 'spurs', but simply 'branches' of the radial, and one can have as many sockets on each of those branches as one wishes.
