true you can take diversity into account, but... how often are you gonna have the oven and hob on all at once? quite a lot imho. sunday dinner... your easily going to have the oven on and all 4 hobs on..
Well that 15KW (6mm/32A MCB/Fuse) cooker diversity formula, has worked for around 60 years without any problems from Sunday dinners, Xmas dinners or any other types of dinners!! lol!!
It is highly unlikely that all of the hob and the oven elements will be on at any one time for more than a few minutes, they will all be cycling through their individual thermostats, that will probably be set at different settings. You can also knock off whatever the rating is for the ''Grill element'' within ovens, as the main oven and grill element can't be operated at the same time...
