Is this 6mm or 10mm cable?

Measure all 7 strands after arranging them in a line side by side touching; reduces measurement error..

(Anyways, does it matter the exact measurement or cable? With the CSA it has, does it provide the CCC you need?)

How strange - so was it "Scolmore technical team" who 'plagarised my table in the DIYnot wiki? I find it very hard that they will have come up with a virtually identical table as mine, both in terms of contents and format, "by co-incidence"

Immitation is the highest form of flattery Sir.

Thanks for the replies. My question was about the supply cable to the extension CU. It hasn’t been repurposed as there was nothing there before the extension.

If that cable is big enough (and I think it’s been established that 6mm isn’t) to consider running a supply to change the ovens from gas to electric (enough for two double ovens and an induction hob) then that’s all I wanted to establish.

I guess the electrician will decide the size but why not use 10mm out to the kitchen, just so you have ´capacity’. Or isn’t it as simple as that?

Just looking online, a double oven was 5.9 KW, so two of those make 11.8. Add in an induction hob, say 7 kW. So we’re looking at 19kW.

After diversity I think that translates to 32A plus another 5A for a switch.

The cable will mostly cross the joists so won’t be clipped to them - does that make a difference?

It comes to 30.5A.

You only add 5A if there is a socket in the switch - so don't have a switch with a socket.
