Cable Diversity for Induction Hob

Former Community Member
Former Community Member
Hi all,


I have been tasked with wiring an induction hob, and I’m fairly new to install work on my own having just qualified myself and venturing out on my own. 


The Hob is rated at 7.35kW.

In my head, and applying the cable diversity factors-

7350w divided by 230v =31.95amps.

Take off the first 10amps =21.95amps

21.95x30% = 6.58amps

6.58amps+10amps =16.58amps Total.


Plus 5amps if there is a 13amp socket involved, which there isn’t in this case.


so with that in mind, I’d be fine wiring the circuit with reference method C (clipped direct) in 2.5mm T+E right??! Although saying that, my thoughts are to wire using 6mm T+E just in case future appliances vary! 

does this seem logical or should I just keep it as a 2.5mm circuit on a 20amp MCB.


any advice would be greatly appreciated. Let me know your thoughts?

    AEG are very naughty not to include installation instructions specific to the model - part of that doc mentions plugs and sockets, and the other half having it hard wired, clearly generic cut and paste  - utter nonsense. 

    It might be fun to call them and ask for the recommended cable cross section in mm2.  (the spec they give -  H05BB-F or H03V2V2-F - just  defines types of rubber covered flex, but it is available in 1,5  2,5 and 4mm cross-sections so no help at all really)
