6mm or 10mm for cooker?

[HappyHippyDad]

I don't think I've ever come across a cooker that needs 10mm but I may err on the side of caution with this one.
Rangemaster Leckford deluxe 110cm induction range cooker.
14.8kW, states required a 45A supply.
No info on cable size.
With diversity a 6mm will be ok. Plus ref method C gives a ccc of 47A for 6mm.
But... it's close. Would you use 10mm?

I bought new Range-master estate 90 dual cooker, I have got 6mm coming from the fuse for the old cooker. The cooker requires a 10m for connection. Now do i have to take a 1om from fuse box to the cooker socket in the kitchen. Please advise.

10mm for the entirety of the circuit, time to get a spark in

Please advise if i have to replace the 6m for 10 m from the fuse box to the kitchen box for the new rangemaster cooker estate 90, make connection from the cooker to that with 10m

You mean i have put a new 10m from the fuse to replace the 6m

You mean i have put a new 10m from the fuse to replace the 6m

Yep from the consumer unit (fuse) all the way to the isolation point and then on to the cooker connector plate…..have you thought about a lower power oven?

So 10m from the fuse box to the main cooker socket replacing the 6m. That would need an outlet box to. Please advise on that. This cooker do not have any cables attached to it, you have to make it from the 10m cable to attach to the cooker socket. Pls correct me if i am wrong. RANGEMASTER DUAL COOKER ESTATE 90.

what mean by lower power oven, elaborate pls. This is rangemaster estate 90 dual fuel cooker

 

[Baddegg]

Sorry mate was implying it would probably be cheaper to get a lower kw oven and use the existing 6mm, assuming it’s ok

No you’d need an equivalent size flexible and probably heat resistant cable as 10 mm flat t&e isn’t considered flexible and suitable for moving the oven in and out, I’ll be honest and I rarely use this statement but I think you’ll need an electrician to install this for you

RANGEMASTER DUAL COOKER ESTAT I had one of those exact same range cookers. I did pre install a 40amp supply. The engineer from Range Master

I had a Range Master Dual fuel. They required a 40A supply. After install, I clamped the supply, and with everything at full bore, I only every got a reading of 14A.

What model have you got?

Flexible cable is not required for appliances which are only moved for occasional maintainence access. T&E is permitted in this situation.

 

[brianmoooore]

Are you certain the model number you gave is correct? Manufacturer's spec. gives a maximum electrical load of 7.4kW before any diversity is applied. That does not equate to 10mm2 minimum supply cable unless the cable has several derating factors applied to it, or is unusually long.
IMHO, the manufacturer is exceeding their remit by commenting on the size of the supply cable. That is down to many variables which they cannot have any knowledge of, and the required size should be determined by the competent electrician designing the circuit.

Rangemaster estate 90 dual fuel Now i have got the old 6m cable from the fuse box to the kitchen socke, which is the Wessex White 45A DP Cooker Unit Switched Socket + Neon. But this cooker requires a 10m cable as stated in the use guide. Does mean now that i have to bring a 10m cable from the fuse box to the kitchen unit and then 10m cable to the cooker. Plus an outlet unit has to be attached to the cooker unit. Pls tell me if this the right way.

Read and understand just what Midwest is saying. If you cannot understand get in touch with someone who can.
Whatever, get someone qualified, in person, to sort out your problem, on site.
Not a DIY job.

If you read this thread from the beginning, you might be more informed. I’ve just tried to find the total electrical load for this oven, on Rangemaster web site, but can’t find it. Perhaps you can OP, then we might be able to provide the total load after applying diversity.

In my case, I had previously fitted a 40A supply, some time before. Later we decided upon this oven. Only had Rangemaster fit it, as removing the old oven was part of the deal. When their engineers came, he said he was glad I had a 40A supply, otherwise he couldn’t fit, which I thought was nonsense at the time, hence me experimenting, by clamping it.

If I recall, it has main electric oven, smaller side oven and a grill. Post those individual figures.

 

[Eddy Currents]

If that model is correct then according to the pdf spec on their website it states a maximum load of 7.4kW

The cooker requires a 10m for connection

Where did you get this info from?
The only reference I can see to cable size is on P29 where it shows 10mm max which is the maximum cable size for that connector

Maybe you can supply a photo of the voltage label on the back of the cooker to confirm exactly what is required?
