oven / induction hob question

[adam.h]

Customer is having 2 ovens, both rated at 3K55W each so 15.5A

Would the best way be to run two 2.5 radials on a 20A mcb or have them on a 4mm ring 32A breaker (or rad even to seperate them?)

Also, they are having an induction hob rated at 7K09W, 31A. Would sticking this on a 32A mcb be cutting it a bit fine? otherwise it's 10mm instead of 6mm.

With the 2 ovens there is no reason not to put them on the same appropriately sized radial as long as they are both within 2 metres of the control switch.

With the induction hob i would consult the manufacturer just in case there is a power factor associated with it.

So it would be ok to have them both off the same control switch? Didnt think you could do that?

It's ok, have a look at the On Site Guide Appendix 8.4
"A circuit of rating exceeding 15A but not exceeding 50A may supply 2 or more cooking appliances..." goes on to say they must be in same room and within 2metres of the switch.

For convenience and safety I would put each oven on a seperate switch.
