Induction Hob - Safe to use existing cooker circuit

[BeardyJaws]

Agree totally.
Too many installers go over the top with cooker circuits.

I suspect that’s because we are told at college, or certainly at mine, that diversity applies to the DB and overall installation for working out capacity.
If the cooker is capable of drawing 50amps then we were told to design for that and not to apply diversity. But when you’re working out the total capacity of the DB diversity then applies.
I had the discussion at college and at work. If I apply diversity at college I would have failed that section. If I do as college says it goes against current practice from years of combined experienced professionals.
