New sockets

[EFLImpudence]

Just spend the £7.50 and keep the 2.5mm² for when you need that.

Then you won't have to come back and ask about ring circuit limitations when you want to add more sockets.

and he says that he already has 2.5mm² cable.

Irrelevant.

Is a 4mm cable on a 32A mcb ok? I thought a radial circuit in 4mm should be on a 20A. Just what I've read and very happy to be corrected!

When you mention ring circuit limitations, do you mean the maximum area the ring can cover or something else?

Thanks for the response bars

Ah that's for 2.5mm radial?

Yes.

Not correct.
You can have a 2.5mm² radial on a 20A (or 25A)

No, I mean all the special rules involving FCUs etc.

On a radial you can add as many branches (spurs) and with as many sockets on them as you want.

Yes, provided the cable is not 'buried in insulation' etc., 4mm² is OK for 32A. 4mm² 32A radials are perfectly 'standard'.

That's right.

Kind Regards, John

Thanks. Perhaps 4mm radial off the 6mm is better then. Avoiding testing issues in the future as you say and seems more common in this instance.

So - not much point having a ring, then.

I said that to Mrs Secure, she was less than impressed.

For what it's worth, that's probably what I would do.
