14.8kw range cooker

[Liam12]

Need abit of Advice, on a new build and was told this cooker was to be installed ( as shown in title ), total load would be 64.3 A, obviously applying diversity chances are it would never reach that but having trouble find a suitable breaker. Baring in mind this is only a single phase installation a 63A is the highest available, (to my knowledge and have also asked wholesaler), any advice would be grateful as its abit of a weird one for me and thought its worth your opinions , cheers

Never mind chances are mate it will never draw 63A. That is what the manufacturars put on, it's what it would draw if everything was on full belt at the same time. Apply diversity and you'll have a more sensible idea of what you'll need to install it.
As an example, how many ovens does it have? I'll bet one if not more of them has a grill function but you can't use both the oven and the grill at the same time so there's probably 4kw minimum gone straight away

I installed a 32A circuit for what I thought was going to be a dual fuel range (gas/electric), when it turned up it was an all electric one and had a 17kW rating. Couldn't do anything about the cable so it had to stay on the 32A, no trips yet and its been in for 2 years.

whats it say in the manual, a 40 amp circuit breaker and a 10mm2 cable probably, have a look at the manual.

cable 6mm on a 32A MCB. this could be increased to 40A if cable is ref. C. this method has been in use for donkeys and is good for cookers up to a rated wattage of 15kW.

I installed a 16kw all electric range master recently and manuf data said 10mm / 40-45a mcb

I have a 17KW range cooker on a 32amp MCB, four christmas dinner later it has never tripped. Doubt it ever will either. My mum and dads house has a 13KW oven on 20mp MCB wired in 6mm. CEF gave the wrong amout of MCBs(supprise) Even that has never tripped
