electric oven and hob plug- hard wire

[koolkat]

Hi. I need some advice with the installation of my electric oven and hob. The oven is a New World NW60F and needs 1925 w, and the hob is an Ariston system 2000 which draws 7000w. I am thinking of use a plug and socket for the oven and I assume the hob needs to be hard wired. The image shows what I have in the space at present, plus there is a cooker switch on top pf the counter. Can I use the socket on the left for the oven (adding a plug to the existing oven cable) and hard wire the hob next to it? There aren’t any other socket apart from one on top of the counter quite far.

Also, what kind of plug would I need for the oven cable, it is very thick.

Thank you View media item 53403

Is the socket on the same circuit as the cooker outlet?
I.e. does the cooker switch control it?

What is the rating of the fuse/mcb for the cooker circuit?

Yes you can put a plug on it.

Will that socket be accessible though once things are installed? If not then you can't use it - you need an accessible way to isolate the appliance.

Cable looks far too big - 4mm²? You'll never get that in a plug.

Is this a second-hand oven? Unless the instructions say you must have it on a 13A fused supply, with a cable that size you could connect it to a cooker supply, and I'm wondering if that's how it was connected before.

If you want to put a plug on it you'll need to replace the cable - 1.25mm² or 1.5mm² will be fine.

On top of the counter there are actually two switches. One is marked 'ignition' and control the socket on the left. The other one is marked 'cooker' and doesn't seems to control anything although it lights up when on...

not sure how to find that out.

Yes as it is controlled by the 'ignition' switch

It is my old oven and previously it was connected to the cooker supply in another flat, but I had two points...now I only have one, and I'd like to use it for the hob which must be hard wired.

This is likely turning the feed to the cooker connection unit on the right of your picture, I would leave that switch off when you've got cover off

As for the fuse rating, if you look at your fuseboard / consumer unit there should be a circuit labelled 'cooker' or similar, it will have a number on it (amp rating), for example, lights will be 5a (if fuses) or B6 (if MCB's), finding this first might make it easier for you to then find the corresponding number on your cooker circuit

This is what I found: Cooker: Mcb 40, Type B, Cable size 10, Cpc size 4
Kitchen sockets: Mcb 32, Type B, Cable zize 2.5, cpc size 1.5.

I would connect both the oven and the hob to the outlet plate.

Dual outlet plates are available if you cannot get all the wires in the present one.

the outlet plate is the one on the right in the image, m I correct?

 

[Iggifer]

yup

 

[EFLImpudence]

Yes.

 

[koolkat]

something like this?
http://www.ebay.co.uk/itm/COOKER-OUTLET-PLATE-45amp-DUAL-TYPE-HOB-COOKER-/250508521047
except that is 45 amp

 

[EFLImpudence]

That's it.

The 45A is just maximum current it can carry
so anything over your 40A mcb will do.

or this:

which is considerably cheaper, and a recognised brand.

It doesn't matter that accessories are rated for a higher amperage, it just means you could put 45a through it and it would be fine, because your mcb is 40a you will only ever put 40a through it, so it's fine

Seems quite straightforward, I'll have a go and keep you posted!
Thank you all!
