2 X Single Ovens

[Clarkster]

 My question regards my kitchen ring.

I have a 32 amp mcb providing protection for the kitchen.

Previously  I have had double ovens where it is obvious should be hard wired back to the CU.

This time I have gone for TWO single ovens, traditionally a plug top would suffice for a single oven. But what in the case of two.

Out of interest I worked out they would each draw a Max of 15 amps, so my question is should I provide them with a dedicated 32amp breaker complete with switched fused spur for each oven or just use plug tops on the kitchen ring. Come Christmas Day the only burning smell I want to be smelling is turkey.

i think you have answered your own question,

if you have worked out they can draw 15amps, what size of fuse is in a plug top?

I would probably say a 16a radial for each oven, with a 20a DP switch.

 

[Steve3948]

Single ovens normally state should be fused at 13A, if fan assisted, not seen many without these days.

What does the label say in kW terms.

I fitted one yesterday and it stated a minimum of 13 fuse so banged in an fcu as I didn't have much option. But if I had to run a new curcuit in then I would do steps option

As Stepps says ,  you can't plug them in as they are rated at 15A each so two 2.5  radials I'd say. 

 

[Steve3948]

But do they draw 15A, what make and model are they.

I know there are bigger units about but a lot are 2.4 kW ish, where oven and grill will not operate together.

 

[kerching]

Dont use thenFCU that pro dave used....rated at 13a BUT could not handle 10 A!

condemned a job last week........single Oven plugged into one side of a double socket.........Oh!......and the other side of the double socket had a 6.4kW Hob plugged into it!!!

just condemning....

I assume they are 7.5 amps per oven reading this right. I personally would keep them on a 32 amp circuit and just have them plugged in. It just future proofs it if you do it this way.

thats how I read it,

I tend to think in straight lines , not always the best ,   but he said " EACH OVEN  has a maximum of 15A"

He.s the guy onsite , I have to believe him,  so two radials  or split them across a 6.00mm I 'spose with two isolators.

I would have said that's the way it's got to be otherwise you would have a 1.7kw oven would the cook anything? Its 15A per oven, which sounds near enough for a self cleaning oven. 

I also bet there's little diversity I'd imagine both ovens being put into cleaning mode at the same time and them to draw a constant-ish load for some time, I take it the cleaning program takes a while. 

 

[Chewbacca]

plug top really not advisiable - high resistance will lead to mucho burning, maybe not for a year or two, but it will happen. Any appliance that draws a highish current for long periods of time should be hard wired

 

[Steve3948]

I've got a self cleaning oven, its also called the wife  :innocent   :innocent

I bet you wont let her see that post,,,,,,,

So very true, I would not get any food ever.

Thanks for all your help, I've decided to go with a 6mm cable (radial) from a 32 amp mcb going to a 20amp dp ccu (45amp ccu may have more room for 6mm cable)  then out of that ccu and into the next ovens ccu which is about 3m away. What do you all think about that!  

 

[steptoe]

mmmm

not so sure about having a 20amp rated accessory on a circuit designed to carry 32amps,,,,,,,

and yes, I do know about sockets and ring finals being over/under-rated, the rules are foolish.  :C

 

[batty]

So I assume you mean cooker switch when you say ccu it used to me customers consumer unit when I went to college. I have never seen a 20 amp cooker switch.32 amp is the smallest. I did ask if the ovens are 7.5 amps which you have not yet answered. I would need more info to answer your questions.

 

[Clarkster]

Thanks for getting back to me. Each oven has a max draw of 15amps, I intend to use a 32 amp mcb at the consumer unit then run a 6mm radial cable to the first cooker connection unit (45amp dp seem easy to get hold of). Then on to the second cooker connection unit.   

 

[ProDave]

Cooker Connection unit to me has always meant the ones with a cooker switch and a 13A socket in them.

Otherwise it's just a double pole isolator.
