Extending ring circuit

[LabourForApprenticeship]

Morning all, i plan on extending ring circuit, installing additional 13A socket in the room.

Plan of action was to install black 30A junction box under floorboard to one of the legs. However after some research on this forum, junction box must be easily accessible and not suitable for the job. I'm not too sure if i will either go with carpet or permanent laminate flooring.

What would you guys suggest, 3 wagos inside existing backbox and extending from that

Or

Wago box under floorboard

Or blue crimps again inside the boxbox.

Thank you in advance.

 

[telectrix]

wagos in existing socket box for me. if only 1 socket added, no need for FCU. unless you don't want to chase decor. in that case a MF box under floor.

Hager j803 but why not a spur

Why not extend the circuit from the sockets themselves? Removing the need for any junction boxes.

Thanks pal.

What is a FCU? And which MF box would you recommend? Screwfix product please as i plan on completed job today before lunch.

Is it better not to integrate into ring, easy enough.

There's no flooring installed. Chasing socket shouldn't take longer than 10 minutes with armeg scutch chisel.

No unless it’s for a heavy load appliance ..... are you sure it’s a ring?

 

[Spoon]

No

Curious as to why 'No'

Ah, you have added to it now.... Still see no problem with extending the rind if it is easy enough...

 

[telectrix]

doubt if screwfix do a MF box.

Hit, nail and head

Screwfix is for builders and DIYers

Yes.

Only place open today. For work, we use erf or electric center

 

[telectrix]

screwfix is fine if you want something at the weekend.

Screwfix can be a Godsend for any Tradesperson including an electrician working on a weekend, and in need of some cable etc when most Wholesalers are shut.

The OP intends extending the ring, not spuring off from the ring.
I would use crimps in the back box.

Screwfix have gaping holes in their catalogue .........

I think I'll go with crimp, finally unpack my brand new crimper

Plus I'm a cheapskate.

Must have been a glitch somewhere then Mate, when I worked for them the stock control was very good.

If the OP spurred from the nearest socket outlet, then he wouldn't need to crimp anything!

 

[Spoon]

Ok, I must have my thick head on today.
Why, if you can get to the back box of the socket not just extend from the socket itself?

 

[Octopus]

It’s not stock control, it’s whats on the shelf in the local stores ...... not in the central stores

 

[Deleted member 26818]

Another option would be to pull a leg out of the existing socket and crimp to that under the floor.

First time doing this...spurred of before but im a heavy user. I could use heaters which are power hungry. Also i run alot of computer equipment for work purposes 24/7. i think it would be better suited to extend ring given that it would take same amount of work.

If they are the standard red/blue/yellow crimps, they are not designed for use on solid conductors and do not provide any guarantee of a good, long lasting connection.

For solid cores you should be using uninsulated indent crimps and then the necessary good quality heatshrink sleeving to insulate them.

For extending rings in back boxes I find the Ideal in-line splices are fantastic...

Stock control in the Screwfix outlets are controlled, updated on a daily basis, from personal experience, I can vouch for their product maintainability.

 

[Deleted member 26818]

Last time I checked, there were many crimp manufacturers that state their crimps are suitable for solid conductors.

I wouldn't use them due to the nature of the crimp construction. As you know, typically they are a split tube which is simply pressed into an oval shape when crimped. Usually it's quite a thin wall on the tube and I'm just not convinced they stand up well to the thermal cycling they may experience.

I've certainly tried a variety of crimps on solid cable in the past and not had much joy (various crimp manufacturers and various crimp tools), and I've pulled far too many apart with very little effort that have been installed on sites I've worked on, so I just steer clear and use things like the SpliceLine and Wagos.

 

[Deleted member 26818]

Both of those will work, though they would need to be within an enclosure.

They are Ideals Wago and will do the job. I find the SpliceLines are easier to secrete in the backbox, particularly if it's a bit tight.

The red, blue and yellow crimps are usually barrel type, with a thin wall solid tube inside a thicker wall split tube.

I needed some piranha's last week - NONE of the local stores had stock and ALL had them on "over night" delivery........

 

[LabourForApprenticeship]

I know at work, we use standard insulated crimps if the cables need extending... I go by what the boss requests.

This jobs for my own home, so rather do the job the best way possible.

I've not seen any like that. The one's I've seen have always been the split tube is the main inner.

Would you mind pointing me in the direction of that style please?

Company called AMP.
Although saying that it appears some of my crimps do not have the extra tube.
Crimp pak and Engex, don’t.
I think the extra tube ones are called ‘faston’.

Thanks for that... will take a look

They can be a bugger with fine staranded wires, as the strands try to go between the tubes.

 

[LabourForApprenticeship]

For future reference, what would you guys use for stranded cables?

Also... Are connector blocks no good for this application?

Lever wago connectors personally for stranded

Connections much be maintainence free
Screws work loose over time due to a couple of factors..

 

[Spoon]

Or solder stranded cables together and use heatshrink

 

[Deleted member 26818]

I think the biggest problem with crimps, is not that they are not suitable for solid cores, but that they are often not crimped correctly.

 

[Midwest]

Screwfix sell Wago's 222, 221, Wagoboxes, Spliceline connectors, Pushwire connectors, crimps (not sure if they are barrell type), heat shrink, pretty much everything thats been mention. And in stock on a weekend

 

[Pete999]

Thought only old fashioned Barbers asked that sort of question.

I've never had any trouble with correct size installed properly. I can't understand the problem.

 

[Taylortwocities]

Jeez. 48 replies for one additional socket...

He was planning to have this done this morning

Well, all I can say is that why this place is interesting because you get to see a whole range of opinions and experiences.

As I said, I've tried various makes of crimps, various crimpers and never had much success with solid core wiring. Stranded cables yes, but solid no.

These days I just try and avoid insulated crimps unless absolutely necessary (used a couple the other day to fix an LV light in a room at the hotel I've been working at, worked a treat, good strong connections). The only time I generally use crimps is indent crimps for joining big cables and terminating earthing conductors and such like.
