Wire sizing

[Choochoo]

Hi everyone

I am installing our new cooker soon which has a gas hob with an electric fan oven. Am I right in saying that as it only has an electric oven I can use 2.5mm wiring and 20 amp socket with a 20amp disjoncteur. Does it need to be wired to the AC or A interrupteur?

Thanks for all help.

Hi

In theory yes.

It depends of course on the load of the oven, for example it would be no good for a 5 kw oven, I think your good upto 3 kw, anything over and you need 6² cable and 32 amp disjoncteur.

I am assuming you will not be needing a conseul inspection ? , since the 32 amp Type A circuit is required as a minimum standard installation whether or not you install an electric hob or not.

For peace of mind, taking into account the extra cost, (minimal), I'd go for 6 mm sq and 32A disjoncteur, through the Type A RCD. I've also NOT used a socket, but a proper French cooker connection.

It's what I've done, taken straight from "L'Electricite, Pas a Pas".

Take a look at the oven spec.   A lot of single fan ovens are only rated at about 10A.

I'd STILL rather do it by the book. You can always change the disjoncteur for a differentt spec, but the cable, if too thin, can't easily be changed, should you buy a more powerful, current hungry oven.

If it helps we had ours installed by an artisan and we have a special cooker plug, the wiring is 6mm and the breaker is 25A.

Thanks everyone. I have a type A and a Type AC as required. I shall err on the safe side and go for 6mm and 32A
