Spur from Ring Final Circuit

[Gigsy]

Best you adopt a more grateful approach in the future if you expect people to help you.

Ps. I don't think it's your home ..... Not in the least.

Who's home is it then?

They are push fit terminals with cable grips!

Are the connections in a suitable MF box?

Who's home is it then?

Some unsuspecting customer's?

Not many DIYers have the BYB to hand!

But nobody has given me any advice on the proposed design??????????????

Are the two joint boxes where you intend to break into the existing ring final circuit.

Now I've had a little more time to take a look at the regs I stand corrected. It seems to explicitly state the regs are for work only. That raises a discussion in itself to me - they should be all encompassing no matter the situation. Anyway, I was wrong.

Can you imagine how many DIY electrical jobs will take place this weekend by persons with no clue about what they are doing in terms of safety, that is just two days to make the world a more dangerous place. At least the op is seeking guidance, whether he chooses to heed it is another thing. If he chose to he could lash the sockets in using two core flex, there is no one policing him.
It will only stop when people can no longer buy the necessary parts over the counter but that will never happen.

Hi Gigsy...

Look at appendix 15 of your regulations BS7671 and you will see a diagram of a circuit and what is ok and not ok regarding making alterations to your ringmain.
As you are doing your own work here without qualifications regardless of you been in some form of training then you will be deemed as DIY and as long as you are not undertaking such work for others and/or been paid for the work and this is your own property then maybe fine to undertake the work but crucially this depends on your competence to do the work and your ability to do it safely without risk to you, the property or others, our members will respond accordingly to the posts and replies you make as to whether it is advised to get a competent person in or they deem the work you intend to do is within your capabilities - this is why filling your profile out aids us to respond appropriately according to your level and experience, lacking such info then we have to take the side of caution and make a blind judgement solely on how you reply to your posts.

If you have other tradesman in while you are doing such work then things get very complicated as you would need to have some kind of insurance to ensure you are covered if anyone is injured or killed as a result of your work or actions as do they to work alongside the public. Its not just a matter of doing a DIY job and thinking your exempt from the requirements if you wish to work alongside other trademan then you will need to be under the instruction of a competent insured person or be one yourself, I know this doesn't happen in the real world but that's the risk you take as you can easily find yourself in court with no defence if an accident were to occur as a result of your work or actions.
Some companies will specify a competent insured person/company does the electrical work if it coincides with there time on the job or they may refuse the contract.
It not only about defining the difference between a notifiable job and a small DIY project but also the circumstances the work is undertaken under.

This is why you will be subject to a barrage of questions when you ask in the DIY section about doing work that is normally considered a little beyond basic DIY as it goes beyond replacing a light switch or fitting, socket tops etc, with the actual risks that come with working on your electrical installation can be deadly we have to ensure we give the right advice to the right people and thus you can get 2 different people ask the same question and get very different advice as we assess there competence to undertake such work.

So don't get frustrated if you don't seem to be getting your initial question answered straight away but its like I said earlier, the more info we have like your background etc the quicker we can give you an answer to suit your circumstances, and if its not the answer you want to hear then sometimes that is the way it is as that may be the best advise for you given the info you have provided.

Just browse through section 15 and hopefully your initial query will be answered.

My last thread was taken down due to copyright reasons, I think it was because I scanned a page from the wiring regs and posted it.

Can anyone tell me if this circuit design confo/rms to regs?

View attachment 34318

In theory yes if installed correctly. It will be an unbalanced ring final but will conform.
As for testing / building control if its your own house worry about building control when you sell it but PLEASE test the ring final and spurs (sounds like the spurs are existing to me and will cause damage to decor.and tiles hence there need)
You must use maintainence free junction boxes. the j803 in your drawing is ok.

Testing is to make sure it is as safe as possible and to avoid nusiance tripping.

It will be an unbalanced ring final...

I don't think you can say whether it is or isn't. The drawing is unlikely to be complete and to scale.

 

[Gigsy]

Are the connections in a suitable MF box?

They are push fit connectors with cable grips, so evidently yes they are in a suitable maintenance free box!!

Have you never heard of a J803?

Some unsuspecting customer's?

Not many DIYers have the BYB to hand!

Can people stop using acronym's please, what is a BYB?

 

[Gigsy]

Yes, exactly correct, thank you for your interest. The drawing is the exact ring too.

Because I didn't get a reply two days ago, as to if the proposed circuit would be safe, I destroyed the wallpaper and chased the walls and put in a ring without any spurs. Well got the cable in, not wired it up yet!!
