extending ring

[martysparky]

I have to wire a feature wall. basically the wall has been altered and a double pole switch for a potential lift is now inside a new stud wall (New house).

I want to use the feed from the switch that is on the ring main to feed sockets for the TV and media plus some lighting 200w max.
As access would be awkward to the dry lining box I have been considering crimping the ring main and extending it about 10 inches to S/F/C/U to supply the sockets. Then spur of the F/C/U to another F/C/U to supply the 200w down lights.

Sound ok or is there a better way anyone can suggest?

What about changing your single dry lining box to a dual.

Dual 35mm Dry Lining / Plaster Board Box

lost me there dude?? however I could use one of those for the f/c/u's...yup

 

[Sintra]

Sorry must have mis understood your post.

 

[martysparky]

Thanks anyway sintra.

My concern with crimping is holding the cable ( ties ) would one of those Ashley maintenance free boxes be better?

I did something similar today with crimps. As long as they'd still be accessible (in the back of a socket) can't see there's a problem. Or do you mean losing them in the wall? Would wagos be any use?

 

[martysparky]

I did consider Wago but don't have any and cant get any by tomorrow.

I do have plenty of through crimps though and thought they were maintenance free as can be buried in plaster.

Its just the thought of them being pulled out, as wont be in plaster, but not that its likely.

 

[cornburn]

If that's all you have then I'd be happy with that as long as they're crimped properly and nice and tight, pretty sure they are classed as a permanent connection

 

[martysparky]

yes, I have a ratchet crimper.

Thanks.

Blue through connectors are rated at 27A Why not 32A?

 

[m4tty]

They won't need to be rated at 32a on a ring will they. As the load will be spread between the two legs? Cheers

 

[martysparky]

true enough. so why do a lot of manufacturers make connectors rated at 32A for a ring when 2.5mm2 cable carries 21A?

just a thought?

As I've said in another thread, if the cores you're thinking of crimping are solid, then I wouldn't crimp them. If you can get Ashley maint free JB's tomorrow that would be your best option. If there is any chance of that cable moving and it's crimped, they can come loose, I don't care how good the crimper is. My ratchet crimps are very good, they crimp nice and tight, but if you start moving the cable they do come loose eventually.

Agreed

 

[martysparky]

was looking at them actually. a little bulky but worth it I think.

Heatshrinked crimps should be fine, in my estimation.

Is this job taking you into or near Newport, I can spare you a few Helacons if you want, but if you want an enclosure to put them in I'm all out. They'll go in a chocbox right enough.

Properly crimped crimps are adequate, though.
