SPURS ON SPURS Extending Circuits

Thank you, ans excellent 👌👍

Hi, in my home the upstairs sockets are connected via a 32A ring circuit with 2.5mm2 twin and earth cable. In one bedroom there are two single sockets. I am considering changing both of these sockets to double sockets (no change to the number of "accessories").

One socket has a fused switched spur, which powers an outside lamp, I am considering altering this spur to the following: 2.5mm2 cable going from the (newly swapped) double socket on the ring main, to a 13A unswitched fuse box (spur box), then 1.5mm2 cable going from this 13A fuse to multiple double sockets (radially), from the first of these spurred double sockets after the 13A fuse, I will also have a spur going to a switched 3A fuse box (spur box), which will then go to the outside light, also using 1.5mm2 cable. From what I understand, this meets all of the regulations, do you agree? Thank you

Just for reference, all of these sockets mentioned are for accessories at a desk, all low powered (printers, PC speakers, lava lamp, Alexa etc). Of course they will be protected by the 13A fuse in case of overload anyway.

👍

many kitchen now are not using a the cooker point (ie using gas cookers or just air fryers combo microwaves), in this situtation can the cooker radial circirt be converted to a radial circirt with added sockets with a 4mm cable, ie if the cooker point of connection is removed and converted to a double socket also?

From the title I was hoping to see the Tottenham 1st team vs the Tottenham reserves. Oh well, I learned some electrical stuff.

This is very useful to someone like me to get ready to do Inspection and Testing soon I really appreciate your effort and time to put this video Thanks again

Brilliant lecture, very well given, thanks a lot

Radial circuit is like having spurs on spurs. How is single piece of cable not overloaded?

Hi there, I am curious and wanting to learn more on this subject. I have an engineering background but no electrical knowledge. Are there any books you can recommend? Thanks a lot

Brilliantly explained thank you so much for creating a clear concise explanation of electrics.

When you say no spurs on cooker radial circuit, does that mean 2 separate 6mm cables cannot be run from the 45amp switch to a built in cooker and electric hob??

Hi, great video.

My garage has a radial circuit. Currently on a 2.5mm. My question; can I add two double sockets spurs off one double socket.
So I have one double which spurs to an outside plug, I want to add another double socket daisy chained off the original socket. Is this allowable/ possible?

thank you so much! this video is extremely well put together and you teach very well. Keep up the good work ;)

You always been a great help.. Cheers dave

This video is absolutely brillant, thanks so much for producing this!

Amazing content👌

Really helpful. Thanks a lot

Very informative clearly described.

Thank you, answered all my questions plus a couple I hadn't even thought of!

Thank you again for another perfectly executed video

What's the max distance of a 2.5 cable you can add to a spur from the ring socket ?

A really great video - subscribed to show my support of this great content

Clear, simple, really, really helpful
Thank you

Thanks, great info.

As always thank you sir for this educational clip🙏

Thanks for this. So helpful

1mm using method 101 is NOT 13a, it is 10.5a. And in todays construction methods it is quite easy for a cable to become surrounded by thermal installation, in which case the cable is derated by 50%, that's why personally, I would recommend lighting circuits to be wired in 1.5mm, or use a ring circuit and YES ring circuits are permissible on lighting circuits.

I've just extended a socket and is voltage reading is 249-252 is this safe.

At the point we direct add a SPUR to 32A breaker what would be the cable size? It should be 4 mm square d isn't it?

Can't you just do a radial 'Spur' of a ring in 4mm2 and add additional sockets without a FCU since the cable is protected? upto 32amp.

Ring circuits are so pointless and dangerous.

Great and very informative video! 👌

I read somewhere that technically we must use the word spur for rings and branch for radial circuits.

I can not understand why 1 accessory is permitted. The MCB can not protect that single cable with a smaller size. It can heat up and damage. Is there a logical reason?

Hi Dave, your videos are very knowledgeable, thanks for that 👍 please could you just confirm for me, I want to add 3 more double sockets in a bedroom on a 20a radial, CAN I DO THIS FROM ANY SOCKET???

Great video, clear a lot of misconception on the Internet by various electricians who have they own personal subjective views

These videos are fantastic!. Thank you very much for producing the content!

These vids are amazing.

Thank you so much for your excellent videos. I've watched quite a few of them now :) I had one question actually. When thinking about an FCU in a radial circuit that's been used to step down to a lighting circuit, could you happily spur from the supply side to an electric socket spur? I hope this makes sense. In my mind, it's the same as installing a junction box just before going into the FCU. Essential this is garage power, there's a spur from the house ring main to a fused FCU, that then runs armoured 2.5 cable to the garage into the first socket on the spur. This then goes to an FCU the other end which steps the wire down to 1.5 for a single pendant light (and uses a lower rated fuse to protect the wire, as I learnt from you!). Many thanks and keep the videos coming :)

Thanks for such a brilliant informative video.

I haven't found a video for this as yet but how would I go about extending the ring circuit to add in another 6 sockets

Slow and clear presentation thanks

Love it!!

How can you use 4mm cable on a 32amp MCB when the 101 method says its rated at 27amps if you could help with this one please

This is very helpful; just what I needed. Thank you.

After changing a single socket point to double socket, can spur (add) a double socket from this point here? Appreciate a reply.

Excellent video

Excellent balance of theory, regulations and practical scenarios. Very clear.

I like it 👏👏👏
