11kwh Induction cooker on 10mm2 and 40a MCB

Anonymous user 01/03/2024 - 2.51 PM

We've just moved in to a house and it's fair to say the cooker has seen better days and needs replacing. At the moment we have a separate gas hob and electric conventional oven. I would like to change this to either a duel fuel freestanding cooker or preferably an all electric dual oven and induction hob for efficiency and safety reasons. I've just looked in our consumer unit and it looks as though our cooker circuit is using 10mm2 cable and is protected by a 40a MCB already. The cooker I have my eye on is a Belling FSE60DOi, which looking at the specs is rated at 10.97kwh. Are we going to be able to change over to using an all electric cooker without any problems using the existing circuit? Seeing as we have just moved into the house (mid 70s build) I have no idea about the cable length and run but it's 13-14 metres from the consumer unit to the cooker as the crow flies, with both the consumer unit and cooker on the same floor. Thanks, James

Hi James, Without all the information about the conditions the cable is run in, it's difficult to give a definitive answer. If the cable runs through insulation, is run with other cables etc, then these conditions will have a derating effect on the 10mm2 cable, also the way the cable is fixed ie in surface trunking, will also affect the cable's rating. Having said all that, the 40 Amp MCB will certainly be undersize as the new cooker will have a current rating of approx 48 Amps. Best advice I can give is to get a compentant electrician to have a detailed look. Kind regards, Neal Haynes Electrical Contractors

Diversity as in the on site guide follows this formula. The first 10A + 30% of the remainder (+5A if a plug socket is incorporated in the control unit). So 10970 / 230 = 47.69A First 10.00A Remainder 37.69A x 30% = 11.30A Add if socket incorporated 5.00A Total using diversity 26.30A Unless otherwise stated by manufacturers which would overide standard diversity. So the circuit as installed would be sufficient unless as stated manufacturers state otherwise. (Below are manufacturers requirements so best practice is to change your fuse rating down to 32A ) Belling FSE60DOi Installation Requires 13 Amp Power Supply No - Needs Electrically Trained Engineer Requires Electrically Trained Engineer To Hardwire Yes - Cable Not Included Electrical Connection 10.67 KW Fuse Rating 32 amps Minimum Distance To Cooker Hood 65 cm Fuel Type Electric
