I would just like to run this one past people.
Customer has three sockets in a kitchen wired as a ring.
The two legs of 2.5mm T and E from this ring come through the wall into a cupboard.
A junction box has been fitted and a single 2.5 T and E then goes back to the DB fused at 32A (don't ask me why FK knows).
Obviously I need to replace the cable from this junction box in the cupboard to the DB.
I was thinking of using 4mm cable as it is quite a tricky route and one cable surface clipped would look neater than two.
So my question is would it be OK to run 4mm from the DB to this junction box where the 4mm cable will then be turned into two legs of a ring each of 2.5 T and E.
I am 99% positive it will be OK but just in case am I wrong?
Thanks.

Depending on what sort of appliances client has, you might consider downrating the mcb and turning the ring from the jb into 2 radials?

ahh-the radial into a ring question again

well it was debated recently so i suggest you google it up

I'm googling but all I am getting is how to turn radial into a ring.
The cables to the sockets in the kitchen on this ring are solid in the wall, tilers have added grout here and there so the cables are solid.
The sockets will be supplying toasters, blenders, kettles, etc.
I will test the wires of the ring tomorrow to make sure they are in good condition, they look OK.

I've found that the search is not as comprehensive on this forum version????? is that true????

Edit: found that easy enough though.

no idea

Don't think 'Radial into Ring', think 'Ring into Radial'. Disconnect the last joining section of the ring part of this circuit so that you have one radial, and put it on a 20/16A breaker, load permitting as Jeremy says. BUT....

there is no reason why this 'lollipop' circuit arrangement - as a poster has previous called it - is a problem. As long as the circuit protection is adequate. Raises interesting questions about testing procedures though.

Thanks for the replies, gonna crash and sleep on it.
Have a think about it tomorrow.
Night all.

Doesn't doing this just turn it into a distribution circuit with a ring on the end of it? As long as the MCB is lower than the cable ratings, and the point where it becomes a ring is accessible, I wouldn't say there's anything wrong with it, provided it's labelled up nicely. Mind you, it's certainly not standard, and to be honest runing 2X2.5s taped up is just as easy as running a 4.

That's my story and I'm sticking to it!

In the trade we call it a lasso LOL

Great names for it.
I've decided to keep it as a ring, it's supplying kitchen appliances that can work out to be energy hungry and the board is getting full up, also it will make it easier to test in the future.
Thanks all.
