You need the neutral to make the light work but you can take a spur from the socket underneath the desk for a light, you could place a FCU next to socket underneath desk then run cable to light switch and then on to light fitting.. you cannot run spur to spur with sockets incase of over load of cable but a light is totally different just fuse the FCU at 3 amps..
Is it possible to run lights via a fused spur?
Is this do-able if just run a 3/5 amp fused spur off the socket and run the cable in 1.5mm to the lights? I`d take it off the lights already in but that means a lot bigger ball ache! Yes you can do as you posted. I would say that lights via a non light circuit are 2nd best from a safety point of view.
Can I use a spur with a DP switch?
For the socket I was proposing to use a spur with with a DP switch because it's an outdoor socket and gives me the option to isolate it if necessary. My lighting "circuit" is not a circuit as such. I have a supply from the CU switched to operate three LED light strips on the ceiling.
Can I run a spur to an under desk light switch?
I've created an alcove for a desk and put a spurred twin socket underneath, but getting to the upper floor and light witch diffciult - so thinking of running a feed through a 3 amp ICU to an under-desk light switch, to the wall, using 1.5mm T and E. Any problems? Simples you can’t run a spur from a spur I’m afraid.
Can I use a 3-pin socket for lighting?
Secondly, you must not use a 3-pin socket as that could encourage someone to plug in an appliance that would not be safe to run off a lighting circuit. Instead you need a fused spur (either 3A or 5A) Third, for the wiring.
Is it OK to spur off a socket?
The easiest way of connecting into a ring circuit is to run a spur cable from the terminals of an existing socket – but you can't connect it to any socket. The IEE Wiring Regulations are very specific about this. You mustn't run a spur from a socket that's already on a spur, or that already supplies a spur.
Can you run a spur of a lighting circuit?
Yes, there are many ways you can address extending the wiring circuit in your home. You could spur the last ceiling rose in the circuit loop. You could run a fused spur from a wall socket or even from an existing junction box on the circuit.

How many Spurs can you run off a socket?
oneAnswered by Rupert, Electrical Safety Expert 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.
Do lights need to be on a ring main?
A ring circuit can then be useful for reducing voltage drop. Either a 1.5 ring on a 6 amp fuse, or a 4mm ring on a 16 amp fuse. In the second case, switched fused spurs with 3 amp fuses are used as light switches....See Also:Technical discussion forums·Other and general engineering discussionsArchived categories1 more row•Nov 7, 2015
Can I add another light to an existing circuit?
Introduction. Installing another light fixture using power from an existing switch is possible if the switch box contains a neutral line.
Can I run a light switch off an outlet?
If you're wiring a new switch, you'll need to install an electrical box. Run a cable to the light fixture and another cable to the outlet from which you're drawing power. Turn off the power to the outlet, and before making connections, test the leads with a voltage tester to make sure they're dead.
Can I spur off a socket twice?
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.
Are lights and sockets on same circuit?
Technically, you can wire a socket onto a light circuit, but it is not recommended. There can be problems with overloading the circuit. If you add a socket to a lighting circuit, do it in parallel. Otherwise, the light switch will control the circuit.

And add the third cable to the socket. So that's how it should look. So this socket is on the ring.
How many 13A sockets are on a spur?
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.
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.
Can I run a heater off a lighting circuit?
There are low wattage heaters you can safely run from the lighting circuit and are designed as such, as has been mentioned there are various infra red light/heater combo units and very low wattage panel heaters specifically designed for running on a lighting circuit.

Can a fused spur be used as a light switch?
Choose a spur with a suitable current rating - normally 3 or 5 amps for a light switch. You can install either a switched fused spur, which will also function as the on-off button or an unswitched fused spur alongside a conventional light switch.

Simples you can’t run a spur from a spur I’m afraid. Can’t you plug ur light in. Other way is to fit a fused spur where you tee’d off the ring. That’s then fused at 13amps. Then you can fit a fused spur off of the new socket
curadh New Member
That could be an idea Nigel! So I would have a fused box underneath or to the side of the twin socket, and then potentially higher up have the other one going to the wall light. A plug in one is not aesthetically pleasing!

I've found an unswitched 13a unit and a single architrave switch in the 'spares' box! Only thing I'm unsure of now is the neutral. The switch is single pole.
curadh New Member
Ah that makes sense, I never knew if the live and neutral actually connected at any point, thought it was some sort of regulation circuit haha so I guess they meet at each socket/ switch.

The role of the neutral, is the live comes down the brown and it returns to the consumer unit via the neutral core. The earth is there for safety and faults.. so if you miss out the neutral in any circuit it will not work..
Why would someone turn off the light circuit and not realise that some lights still remain live?
The risk is that someone would turn off the light circuit and not realise that some lights still remain live due to feeding off a ring circuit AND not competently testing that it's safe to work on ....
What MCB is used for socket in shed?
Socket in shed is on radial 16A MCB circuit in 2xRCD consumer unit (I've got consumer unit with rcbo like this one http://www.screwfix.com/p/wylex-10-way-high-integrity-consumer-unit-10-mcbs/66470) and this radial circuit just for a shed (and small porch at back yard where is also junction box and light via switched FCU) so it's not part of ring circuit or it's not a spur.
Is there always a but in a socket?
But (there is always a but) it depends on what type of circuit and protective device is feeding that socket.
Can you combine a gridswitch with a fuse and 2 switches?
You can combine everything in 1 double faceplate if you use a gridswitch with a fuse and 2 switches. This assumes you don't need RCD protection. If you need RCD on the new wiring then an RCD+FCU is the way to go.
Do you need a fused spur on a single socket?
Try and keep the ring complete if you can.If you are just spurring one single or one double socket off the ring there is no need for a fused spur/fcu.
Can I use a FCU after a double socket?
yes it sounds okay i would use a FCU after the external double socket the FCU can act as the light switch 1.5 or 1.0 mm from FCU to light fitting would be ideal depending on the load of the light i would put the FCU inside the garage what size is the mcb in the garage for the sockets. spirits are real 2016, Oct 16, 2018.
Do you need to turn the outside socket?
you dont need to turn of the outside socket unless you want too incase someone tries to pinch your power you could put a FCU in front of the socket rated at 13 amp dont forget the external socket has to be IP rated (please dont think im calling you thick im not)
Can you run an echo as a spur?
For starters, you need to check the exact manufacturer's instructions for the Echo. It may be possible to run it as a spur from a lighting circuit (mu ch like a bathroom fan or shaver point might be), but only if it is drawing a low enough current that can be supported by the cable and protective device (circuit breaker).
Can you run a cable from a light switch?
If you dismantle the light switch and see more than 3 wires inside it may not be a switched live but on the main loop, in which case you could potentially run a cable from the switch.
