Rules for ring circuits provide that the cable rating must be no less than two thirds of the rating of the protective device. This means that the risk of sustained overloading of the cable can be considered minimal. In practice, however, it is extremely uncommon to encounter a ring with a protective device other than a 30 A fuse, 30 A breaker, or 32 A breaker, and a cable size other than those mentioned above. Because the BS 1363 plug contains a fuse not exceeding 13A, th.
There are several ways that you can create a spur socket from an existing ring main or radial circuit and that is to take a feed from an existing socket or you can use a 30amp junction box to take a feed out to your new socket.Each socket outlet or junction box on the ring can only have one spur connected. Trying to connect two or more is not only very difficult due to the number of wires involved, it can also result in an abnormally high load at that point in the ring.

An older style screw terminal junction box may also be used provided that it is accessible for inspection, testing and maintenance, and is also securely fixed in position.
Trouble is the ring wiring is really tight with very little slack and I don’t have much space. Now I’m considering using a spur off a junction box, twice. So where the ring runs below the socket locations I’d chop the ring, fit a 30A junction box and take a cable up behind the skirting to the new socket, and I do this twice. In this video I show you how to add a new socket to a ring final circuit (ring circuit) using a junction box. In this real life example I show how to locate .

Here is another info sheet from Wago: Can I use a Wagobox to extend a ring main in an inaccessible location? Yes, In a maintenance free situation the maximum Iag limitation will require two separate Wagoboxes to be used as the maximum potential Iag is 64A when using a single Wagobox and this exceeds the BS5733-MF limitation on the box.Each socket outlet or junction box on the ring can only have one spur connected. Trying to connect two or more is not only very difficult due to the number of wires involved, it can also result in an abnormally high load at that point in the ring.

But can a ring mains with a spur from a junction box be mixed with spurs from sockets? From memory it'll be no biggy to put into a socket now if it can't be, just there will be a junction box and join left in place as a negative. Adding more sockets to the study and will almost be a 1 spur per socket for ease for the sockets above desk height. I've added a socket for the TV and run a length of 2.5mm t&e from this. I then plan on breaking into the ring main, which is located a few feet away, and using some Wago connectors and a Wago junction box under the floorboards run a length of t&e to an FCU. That FCU will then be connected to the TV socket and another socket for the virgin box.
