No oven or hob

[diyguy09]

I have have just moved into my house and the old owner has taken the built in oven and hob. As needing somewhere to cook just been down to B&Q and bought a whirlpool oven and hob. Oven is rated at 2.3kw and hob at 5.8 kw.

The cooker switch in feed via 10mm twin and earth about 10m in length to a 40a mcb on the consumer unit. From the cooker control switch more 10mm twin and earth cable goes to the cooker outlet plate. Is it possible to wire the hob and oven into the same outlet plate(oven does not come with a plug) or will i need to get a few other bits and bobs to wire it in.

Thanks in advance.

Any good ?

Yeah looks like what i am after, is it ok for the oven to be wired straigh into this or does it need to be fused down?

Should the hob be wired with 6mm or 10 mm?

tada...

13A plug on the oven..

Many thanks for posting the pictures, very helpful. I am able to find the dual socket holder but unable to find the item on the left, is this just a normal cooker outlet? Also is 6mm cable ok from ccu to outlet then to the socket? or would 10mm be better?

Many thanks

you mean the right? the item on the left is a single unswitched socket outlet.
the item on the right is one make of standard cooker connection unit.

since it's supplied in 10mm, then you should use 10mm from the cooker switch to the cooker connection unit, then at least 2.5mm to the single socket outlet... ( trying to get 3x10mm under 1 screw will be a struggle )

I'm getting a bit of deja vu here, Col!

Shouildn't the same csa of cable be used throughout?

There are cooker outlets designed to terminate 3x conductor.

havent you already asked me that?

no because the reduction in CSA satisfies reg 434.2.1 as it's less than 3M from the protection device placed after it ( 13A fuse limits the current on the cable ).

There are cooker outlets designed to terminate 3x conductor.

yes but they are designed for 1 input, and 2 outputs, which is out the bottom of the fitting, not sure you can use one of the ways to wire internal... ..
in fact going by the picture from the link above, definitely not...

Fair enough, but that's just the first of three conditions stipulated.

 

[ColJack]

yes I know.. but I was trying to make the post shorter...

but if you insist..

tell me then how you think that it does not comply with:-

[code:1](ii) be installed in such a manner as to reduce the risk of fault to a minimum, and
(iii) be installed in such a manner as to reduce to a minimum the risk of fire or danger to persons.[/code:1]

?

 

[securespark]

OK. That regulation suggests (ii) can be achieved by protecting the wiring against external influences.

And one way of doing that would be to up the csa.

 

[ColJack]

it's entirely inside an enclosure, so is mechanically protected, which is usually the reason for using a larger CSA to protect against damage..

I'm not saying DON'T use 6 - 10mm cable, I'm just saying that you CAN use as low as 2.5mm ( probably 1.5mm actually since it's only 13A ).

Thank you for all your help, managed to get oven and hob all sorted today.

Cheers

It's the same as feeding a switchfuse off a busbar chamber

 

[ColJack]

was that for or against my suggestion to use 2.5mm² ?

 

[RF Lighting]

If the supply to the busbar was in 400mm², you wouldn't use 400mm² tails to feed your 6A switchfuse would you?
