oven/ hob diversity

[jimbo86]

Hi.
I am installing a new Hob and oven
the hob is induction 7.2kw
the double oven is 6.8kw and is to be hard wired

At the moment there is a 6mm 32amp supply for the hob
and a dedicated oven circuit on 2.5mm and 16 amp breaker

I have worked the oven with diversity to be just under 16amps.
I spoke to Neff who said it should be installed on a dedicated 20amp circuit.
without diversity it draws 29amps, could this cause a problem?

jujst change the 16A breaker for a 20A (assuming the 2.5mm cable's installation method allows for >20A and Zs complies for a 20A.

Hi. Thanks for your reply. That was my thinking. My main concern is that without diversity it draws over 29amps and if both were in use could this cause the circuit to trip? I have seen other ovens with lower power that say they require a 32amp circuit. Just thinking of the Christmas Day scenario when both are more likely to be used together. Thanks

yes, but with oven element/s on, the grill element would be off.an d if the manu. states a 20A circuit, then a 20A circuit is enough.
