Can You spur a double socket on a ring main?
The first image is how the back of your double socket should look and the second is the wiring for a spur. A general rule for a ring main is that if you only have two cables in the back of an existing socket then it is ok to spur. However, if you have a radial circuit with two cables coming in and out,...
How do you wire a spur to an existing socket?
The spur must be connected to the existing circuit using the same cable as used in the main circuit. You can see how to wire a spur to an existing socket from the images below. The first image is how the back of your double socket should look and the second is the wiring for a spur.
Can a fused spur be extended to multiple sockets?
So if you assume it is un-fused spur could you then replace the existing socket with an FCU, add a new socket beside it then extend to the additional sockets. That way you just have one fused spur, albeit with a limit of 13A on the all the sockets.
How do you test a spur socket?
Finally, check your new socket is correctly wired by using a socket tester. Begin by installing the spur socket and run a length of 2.5 mm² two-core-and-earth cable back to the point where it will be connected to the main circuit cable. The junction box should have the same amperage as the circuit.

Can I run 2 sockets off a spur?
A spur can be connected to an existing socket, on either a ring main or a radial circuit, providing that socket does not already have a spur. That is only one spur per socket is allowed and the number of spurs must not exceed the number of sockets.
Can I add another socket to a spur?
You can't spur an additional socket off of one that is a spur in the first place. You can put a fused spur unit at the origin of the spur then wire the other socket.
How many sockets can you take off a spur?
You can have one unfused spur per socket-outlet on a ring main or one fused spur per socket-outlet, you can have as many sockets as you like off of a fused spur.
Can I add a socket to a fused spur?
You can add another socket of any socket all ready in the ring main, this is then classed as a "spur"on the ring. you do not need to fit a fused spur. But you cant add further sockets from the spur .
What happens if you spur off a spur?
There is no problem in spurring off a fused spur (I think that's what you mean). The principle is you just need to protect the cable. This week I've seen a unfused spur from a socket on the ring to a single socket (in 2.5 6262Y) - then from the single socket to a FCU in 1.5 6242Y for the boiler.
How many sockets can you have on one ring main?
There is no limit on how many sockets you can install on a 32-amp ring main. However, the maximum load for a circuit at any given time should be 7,500 watts. Thus, while the number of sockets is not limited, the number of appliances and electronic devices you use at the same time could be limited.
Do I need to fuse a spur?
A fused spur is used as an alternative to a plug and socket. Due to this, they can allow the higher voltage appliance to operate on a single cable outside of the ring main. Also because they use a fuse, they protect against shocks in the event of an excessive current. This means that they offer an extra safety element.
How do I know if a socket already has a spur?

Why is there only one spur on a socket?
The limit of one spur per point is if the point which is spurred off is UNFUSED. If you fuse it to 13A you can put as many as you want on it. The reason I explained was that standard final ring circuits wired in 2.5mm2 T&E are designed such that any point on the ring will not be loaded above 20A for an extended period.
What is supply and load on a fused spur?
The supply goes to the power source. Load goes to whatever you turn on and off.
Can a fused spur be part of the ring main?
No you can't do that, Mr I. The rules for spurring off ring circuits are you are allowed ONE unfused spur to a socket (single or double) or ONE fused spur to as many sockets as you wish.
When should a fused spur be used?
Fused spurs are commonly used as an alternative to a conventional socket, for the installation of powerful electrical appliances that can be installed without a plug, such as ovens, washing machines, electric heaters, dishwashers, fridges, and so on.

How many spurs can run from a double socket?
the kitchen has its own ring circuit with a 32A mcb. there is a separate 32A radial circuit which i am only using to run a ceramic hob rated at 27A. i have 2x2g sockets in the area but i need to run 3 spurs, one to the oven rated at 2.4kw, another to a 3a hood and another to a fridge freezer 1kwh/day. if i can only run 1 spur from each 2g socket then i am stuck. is there any chance of running ...
Sparkies - how many plug sockets on one spur? - Bike Chat Forums
hehe, im anti ring circuits, i think they are extremely dangerous, it takles 2 faults before a single fault is noticed and inevitably a ring gets a spur which a few years down the line some one adds another socket thinking its a radial circuit, and then someone sees that there is 2 wires coming off it and think that its a ring so add another spur, and so the madness continues,

Can a 30 amp junction box be used on a ring?
The wiring for a junction box can be seen here. Junction boxes come rated for different uses by the amps they are allowed to carry. A 30amp junction box should be used on a ring or radial circuit feeding sockets only. The junction box must be fixed solidly to a suitable surface and must not just "float around suspended by the cables it joins.
Can you spur a ring main?
A general rule for a ring main is that if you only have two cables in the back of an existing socket then it is ok to spur. However, if you have a radial circuit with two cables coming in and out, this may be the last socket on that circuit and already has a spur.
Can you extend a circuit?
Yes, the ideal solution would be to extend or install a new circuit but the OP might not be in position to do that so in the short term, with a few limitations there is absolutely nothing wrong with his proposal.
Can you connect another socket to a washing machine?
That means when your washing-machine is on you probably won't have much left for anything else. I wouldn't recommend this solution.
Can you run a fused spur?
From a fused spur you can run an unlimited number of socket outlets, as they are all protected by the 13a fuse, however, this is not feasible, or good practice in most situations , and wiring your kitchen in this way will almost certainly lead to overloading the fuse and may give rise to problems with isolating equipment.
How to attach a new cable to a socket?
If the cable isn’t long enough to reach the terminals of the new socket without straining, don’t be tempted to pull it. Use a specially designed crimp or terminal block to attach a new short length of cable. But only do this if there’s enough room for it inside the mounting box; all wiring connections must be accessible, not buried in the wall behind.
How to check if a single socket is dead?
Isolate the circuit. Use a socket tester to double check that it’s dead. Unscrew the faceplate and disconnect the cables from the terminals of the single socket mounting box. Run green / yellow sleeving over the earth core if you find it bare.
Why is my socket scalding?
Replacing a damaged socket. A socket can become damaged for a number of reasons: a blow can break the faceplate or overheating may cause scorching. If the problem is scorching, it will usually have been caused by overloading the socket, or by loose connections in a plug.
What to do if new screws don't fit?
If the new screws don’t fit the old box, use the original screws. Use the socket tester to check it’s correctly wired . Although you can increase the number of sockets in a room by converting single sockets to doubles, there may be times where you need an extra socket where none exist already.
What is intelligent multi socket adapter?
An intelligent multi-socket adapter has one main and several supporting sockets. When the adapter detects that the appliance plugged into the main socket has been switched off, it automatically switches off the supporting sockets too – which will save you energy. The secondary sockets switch back on as soon as you switch on the master appliance.
What is flush mounting a socket?
Flush fixings to stud wall. When flush mounting a socket in a stud wall, it’s simplest to use a cavity fixing box. This has a flange that sits against the face of a wall and spring-loaded or rotating lugs that press against the back of the plasterboard, giving more flexibility when you’re positioning the fitting.
Can you run a spur from a socket?
If you’re in any doubt about whether the socket from which you plan to run is part of a ring circuit, you’ll need to consult a qualified electrician.
