Spur from Ring Main
Moved in about two weeks ago and noticed something funny about three extra sockets in the second bedroom. Checked them out today, and I have found that the first socket is spurred from a socket from the ring main, and then the next one is spurred from that one and then the third one is spurred from that, which I know is illegal and completely unsafe.
I want to keep the three extra sockets, as with out them the room would have one. Two if I keep the one spurred from the socket of the ring main, but both the wrong side of the room to be of any use.
I am reasonable good with electrics, spent a few of my holidays working with my uncle as a kid/young adult doing electrics, so I know the basics, but would just like check the idea I have to keep the three extra sockets.
My idea is to convert the first double socket into a dual box, and add a fused spur and 1 gang socket. Then connect the 1 gang to the fused spur, and then spur the next socket (2 gang) from the 1 gang socket. Then spur the final 2 gang socket from the previous 2 gang socket.
I know the best way would be to extend the ring main, but that would require a lot of redecorating. It will be done in the future, but I need to make these safer now.
I have made a diagram of what the circuit looks like now, and my idea to make it safer.
Is a fused spur the best way to do it, and will that many sockets on a fused spur be ok ?

View related: Cutting Into Ring Main For Spur2012-03-02 19:51:30Hi,
I want to break into one of our ring mains to add a spur and have I two questions.
1. The break in point is between the last/first socket in the ring main and the consumer unit. Any problems with this? (There are no other spurs on this ring main).
2. I will be placing the new spur next to a socket on a different ring main, so any suggestions on how I should lable the socket for safety? I cannot take the spur from the adjacent socket as I need it to come from the other ring main to plug in an ethernet powerline adapter. Powerline adapters plugged into the the same ring main double the speed of the connection. I have tested this.
Confirmation of the safety aspects would be appreciated.
Spurs off Ring Finals2011-11-27 05:37:17If you take a spur off a ring main (from a socket say) then spur off the spur then spur off that spur then connect back into the ring main at a different point from where you left it.
Would that be a ring of spurs?...
Adding a spur2011-11-04 20:12:06Hi
I need to add a spur for a single socket to the downstairs ring main. I know that the proper way to do this is to feed a cable into the one of the existing sockets and connect to the ring main that way but that would mean chasing out the brick wall and therefore a redecoration job.
Under the regulations, am I allowed to cut the ring main cable under the floor and join a spur to it in a junction box or is that a complete no, no?
Tracing a spur2011-11-02 04:10:25While looking into where I could (or get a spark to) put a spur in for a TV loft amp, I discovered the logical point for an existing spur looks like it is part of a ring main or what I fear is spur on a spur.
Now I am beginning to worry about the wiring in this place.
I know how to confirm if it is a ring or the dreaded spur on a spur unless I have a damaged cable / broken ring, but any ideas on tracing the spur.
Also in my investigation I have found another spur I have no idea where this runs to, but as of tonight I do know it is not the known spur as I know they are on different rings. I had though I have traced the spur but no. Hence I am getting a bit worried.
The suspect spur on spur from the end I know about runs up into the between floors space, the socket that could be the is in the room / wall directly above hence my suspicions. The other runs down into the same space on the landing.
What I am not going to get away with is pulling floorboards up to trace these.
Thanks in advance for any ideas....
Can a fused spur be fitted into ring main2011-10-26 08:33:55Hi, Hope someone can help me. I would like to know if it is possible to install a fused spur in a ring main. Not as a spur from a double socket but actually included as part of the ring. Any help appreciated....
Spur off a spur2012-04-29 10:36:18Hi there,
I am adding an en suite bathroom in my house. This involved removing a socket, which I relocated to the new stud wall within the bedroom. I think this socket was a spur as it just has a single cable going into it, I guess linked back to the ring main.
I would like to add another socket on the same wall, and within the bathroom I need to provide a fused supply for a Saniflo unit and also a shaver socket.
The more I read up about this, the more it seems unlikely that I can simply spur off the existing spur i.e. have the existing socket, the new socket, the saniflo and shaver running off the same spur - could anyone please confirm this?
Am I right in thinking that I really need to relocate the ring main, then bring 3 separate 2.5mm cables off the ring main to power these 3 new supplies?
Thanks for helping....
Dryer on spur trips RCD2011-11-02 22:24:37On moving to a new(old) house, I added a short (2M) spur to the ring main in order to put my dryer in the cellar. New cable, new socket, wired directly into the ring main MCB of my split CU (Memera 200AD). The dryer display powers up but trips the RCD when a drying cycle is started. I ran an extension lead from a socket on the ring main down to the dryer and it works fine. At this point I'm suspecting the wiring or socket for the spur so check it again but it seems fine (but then it should be, it's all new, and only 2M long with a total of 6 connections to make). I tried a fan heater on the spur and it works fine. I moved the spur to a different ring main but the problem still remains as before.
What's your thoughts guys?
Spur on ring2011-11-17 21:39:36HI new to this forum
I would just like to know would be it okay to add a spur but take the feed directly from the ring main circuit breaker to the spur,instead of tapping into the ring at all.
Its just easier to fit twin socket run cable directly to c/u
Ring Main Wiring Question2011-11-25 18:47:28Hi,
First post here, and great site by the way.
In one of the bedrooms I am adding an additional power outlet. On lifting the floorboards I found (conveniently!) a junction box. It looks like the ring main has been spliced and a spur taken off to the other side of the bedroom for the power outlet there.
Is it okay for me to take a spur off this i.e. ring main with two spurs, or should I be doing something else?
3a fcu from a spur?2012-09-01 13:26:12Is there anyone that can clarify what i can and cant do here?
I am planning to install 2 low voltage wall lights either side of the bed. Both of these have a double socket below. I am happy to spur of of these into a 3a fcu and then up to the lights. My problem is that one of the sockets is on the ring and the other is a spur from the ring. I gather i am able to do the fused spur from the ring main socket however am unclear whether the fcu from the spur is allowed or would even pose a problem. It will be a 3a fuse.
I am however able to incorporate the spur socket back into the ring but would rather not get the floor up. If this is the best option i would do.
Any clarification of how to do this would be gratefully recieved....
Spur off ring main FCU2011-11-20 23:28:00I have a FCU on the ring main with the load being a boiler (fused at 3A). Is it possible to put a spur connection off the feed side of this FCU to supply a double 13A socket outlet or do I need to find another socket on the ring main for this purpose?...
Outside lighting2011-11-11 16:12:32Hi, I am fitting a 240V light in my garden, a post type.
My plan is to run swa cable underground from the light to a switched fuse spur inside my house off my downstairs ring main. The ring main is protected by 30mA RCD at CU. Do I need an extra RCD protection at the spur or is it ok because the ring main is already protected.
socket on ring or spur?2011-11-19 12:29:21Hello again,
Is there any way of telling if a socket is on the main ring or a spur without following the cable all the way? Several sockets in my place have single cables going in, so are obviously spurs. Most of the others have two cables going in, suggesting they are probably on the main ring. I know this is not necessarily the case, though! Is there any test you can do to determine this? I'd be grateful if someone could point me in the right direction.
extra 2 gang plu socket off existing spur?2011-11-25 15:02:20I want to add a second double socket in my attic bedroom, however the socket I was going to connect from is a spur from the main ring.
I have traced back the wiring and the ring is in the room below my attic.
Can I just add an extra double socket from the spur or should I run another spur from the main ring?...
Simple Spur from Ring Main2011-11-02 22:24:45Hello
I have a ring main on a 32A MCB protected by an RCD - I want to add a fused spur at 3A. Load is minimal - about 1A tops so there is plenty of room, but is it notifiable/do I need an electrician/will building control be all upset?...
Adding a FCU spur to ring main for a heater2011-11-18 07:47:46Hi - It's been a while since I've posted on here but I need someone to sanity check what I'm about to do!
I have a 1kw panel heater in the main bedroom that was fitted in place of a storage heater (we have Economy 7). It has an FCU connected to the switched (cheap) supply so the heater only works in the night. I want to connect it to the ring main so it can be used at any time.
The ring has 10 sockets on it (4 doubles and 2 singles) and also another 1kw heater in the second bedroom (there are no other spurs on this ring). I am thinking of adding a spur to the ring to connect the other heater to. Both heaters are on the same internal wall and are virtually back to back. I was going to spur into the FCU for the heater that is on the ring. The spur would be no longer than a foot and I would use the same gauge wire that is on the ring. I would also put a 5amp fuse in the two fcu's
I have read that adding an FCU on a spur is acceptable so long as the floor space is below 120sq yards and the total load is less than 7.2kw. We are well in the space requirements and the only other things that are plugged into the ring is a PC, a couple of lamps, a fan and a mobile phone charger.
I think it'll be OK but if someone can think of something I've missed then please say.
Thanking you very much in advance,
socket ring main tripped after adding spur2011-11-15 08:38:33Hi Folks
Need more sockets in one of the bedrooms it only has one.I took a spur from this to feed x2 single sockets and one double does this mean I have 3 spurs for 1 ring main socket.Since doing this my ring main fuse has tripped x2 in last 3 hours.Any advice would be good thanks....
adding a spur to ring main2011-10-30 22:34:28i want to add another double socket in my kitchen to run my washer & dishwasher off. the socket i wan to take the spur off has 2 sets of wires 1 in 1 out. does that mean its the last socket on ring & safe to take spur from?...
Spur without FCU or Ring Main ?2011-11-24 01:33:21Hi , Can I first say that I am a mechanic and not an electrician , so please excuse my ignorance !! lol.
I have spent a long time reading the forum for my answer , and I think I may know it , but just in case I missed something !!!.........
Is there any way of wiring 4 sockets into my new conservatory , without either:
1. Taking a spur of the existing ring and putting in an FCU ?
( I will probably be using more than 13amps i.e. 3KW heater etc etc)
2. Extending the existing ring main to include the new sockets
(due to location of walls existing ring etc , very hard to do!)
SO basically any (legal/safe) way of connecting up 4 extra sockets to my existing ring without using the methods above please ??
Any advice welcomed !!...
Extra sockets but with a couple of issues2011-10-27 08:54:11Picked up some great points from other posts, and have put together the following plan from those which I THINK is ok, but would welcome some comment and hopefully thumbs up.....
[RCD ring main (too short)] > [ADD junction box to extend the two ring main cables by 0.5m] > [wire in an FCU with 13amp] > [two new spurs each to a double socket each approx 0.5m from FCU]
See this below in diagram form (since it doesn't quite come out as I intended - note that the ring main indicated thus || feeds from the skirting into the new Junction box and then to the FCU....with a left and right spur.
The actual load will be:
Spur 1 - Microwave and Kettle or Coffee Machine
Spur 2 - Fridge/Freezer and Washing Machine
This is part of our new kitchen fit that I am doing myself as I can't afford the installation costs. I will be SO grateful for any feedback on this please. Thanks - Brian[/u]...
