Manufacterer's advice/instructions

whjohnson
Been asked to connect up a used rangemaster all-electric cooker. No rating plate but model name is 'classic 90'. It has an induction hob.

Existing cable is 6.00mm on a 32A mcb.

Phoned the manufacturer who said it would be fine, since diversity could be applied but we would have to fit a cooker switch without a built in 13a socket and uprate the mcb to 40A.

I am a little troubled to say the least.

Comments welcome.

    You cannot apply diversity to a single piece of equipment for sizing circuit protection and cable sizing. Diversity can be applied to individual items of equipment when considering the maximum load on a distribution circuit or an installation.



    Where on earth did you dig up that quote from? AFAIK that kind of thinking was dropped from the regulations decades ago - about the time we started using 13A sockets - and cooker diversity was well established even before that.
