Spurs on Sockets in Electrical Installations

Spurs on sockets, spurs on spurs, FCUs on sockets.

Can I add a socket in the garage?
Can I add a spur for the central heating boiler?
Can I take a cable from the bedroom sockets into the loft?

All these scenarios can cause some confusion to many, especially new starters in the trade and those at college.
This short but to the point video is intended to give some guidance on how to comply with the Wiring Regulations.
It explains what we can and can’t do, the breaker sizes that can be used and the very important selection of cable size.

Thank you for the time and effort you put into your tutorials and making them available.

really good clarity on radials in particular for me thanks guys, 👍👍

Incredibly simple and very clear thanks

Great video!! As always! Please do some practical videos where you explain 3 plate method, 2 plate, how to find the switch line etc. Just things you come across on the job, that would be excellent. Thanks again 🙌🏾

absolutely amazing videos and amazing explanations !

Wow! This is very informative, thanks for sharing it with us. It worth it and the best tutorial on the topic for me...dl

Hi Dave, @2:38, is there a typo? 4mm square before FCU should be 2.5mm square? Although 4mm square is still acceptable but not necessary.

Thank you once again for a great video. I am wondering if on a ring circuit wired in 2.5mm can we spur off with 4mm cable and create a series of sockets wired in radial using the 4mm cable?

Great video, I am very grateful. One quick question, in the ring circuit after FCU with 1.5mm square cable, Zs is going to be reasonably heigher. What would be the max Zs acceptable for this circuit?

Hi, great videos. Quick question..on a ring circuit, after a 13A fused spur you mention the cable size is 1.5mm. Can it still be 2.5mm with no issues?

[sarahjones]

Great video and many thanks. I have a question if I may. We are wanting to add more sockets in our kitchen but unsure if it is a radial or a ring cicuit, so don't want to risk adding more than one cocket if it is a ring circuit. What is the best way to add 3 sockets without knowing whether it is a ring or radial. Do we add an FCU and then connect 3 sockets to that? Many thanks in advance. it will be REALLY HELPFUL x

[Joephus]

More a curious question here if you may. How would you explain the need for the spurred cable from double socket to be 4mm to FCU if the load will never be more than what is after the FCU due to the 13A fuse? Is this something to do with under fault conditions if that cable got damaged or something? Thanks!

Awesome . May I ask a question please . I have o e socket in my garaje coming directly from the consumer unit, so it’s a radial circuit . I have taken two spurs off that socket by the way of an MK logic rapid fit face plate.
I have 3 sockets on each spur out . So my question is the RCD fitted is 16amp, but your video says I should use 20amp. Should I upgrade it ? I am using the correct 2.5mm cable .

Thank you for your efforts. Appreciated

Question; when dropping down after an FCU does it have to be 1.5 or can it remain 2.5mm

Thanks

Love these videos, but I have a question. Today I attended a Napit exams and it started with some multiple choice questions. Question was ‘ how many sockets can be installed after a non switched fused spur on ring final circuit’ I got it wrong. Apparently it only 1 can be installed. Do you think this is correct?

[raj]

if the fuse in the spur blows, would the sockets attached to it after stop working too?

[ajayb]

Silly question, Can you do a spur from a light switch to a socket?

Hi Dave, just a quick update. I have checked a course provider and below is the qualification I'll gain doing the 9 week course:

Building regs
18th edition
2391-50
2391-51

Will this be sufficient enough for me to get on to a scheme, or do I need further qualifications. Thanks
