Cooker supply 12kw correct cable size

[Adamk]

Hey guys

I’ve run a 6mm for a cooker, runs about 10metres. The customers has changed her mind on the cooker and gone for a 12kw range. Went back today to finish off and saw this lovely surprise. I know you have to take diversity into account. But for my peace of mind. Would 6mm 32a MCB be fine?

Kind of panicking a bit as the jobs finished.

What you think? Please dont tell me to tell her to change it as that’s not really an option Thanks

I dunno, the guy who fitted mine was a gas safe fitter (mine has gas hobs). He did tell me off 'cos my old 2.2kW oven with manufactures 1.5mm flex was connected to my 40A 10mm supply via cooker connection unit. Should of been connected via 13amp FCU apparently

I did have to refit an AGA all electric monster, about 18kW max load I think. It had been connected up by AGA persons in the old kitchen to a 32A 6mm supply, which had happily existed for a few months. When we refurbed, I ask by chance AGA technical what supply it should have, '45A 10mm'. So, I went down the middle, 32A ocpd & 10mm cable.

The 1.5mm via a CCU is much less preferable to a 13a FCU set up.
In reality The AGA 18kw monster would be fine on 6mm and a 32a breaker (under suitable conditions) as per BS7671 as diversity gives 30.5 amps. The diversity set up has been going for some 60 years and has stood the test of time.

Regarding clients changing their minds. A recent kitchen I first fixed the electric hob was shown on the drawing on the main run of worktop down one wall. Turned up to second fix to find it cut into the beech block worktop on the centre island.
".......We had a change of mind....does it make a difference then?"

Has anybody here ever fitted a domestic cooker on a 32A MCB and had problems with it tripping?

I must've fitted hundreds of cookers including some big lumps in the last 15 years and never had even one report of tripping through overload.

you can get medication for that.

you can get medication for that.

Is it powder or cream...

Think I would need medication after buying a lacanche citeaux , its the price of a car. Someone's earning far too much money.

I brought it off Someone for a third of the price..It was in their second home and only used a handful of times.
