Installing two ovens on a single circuit

[HughJarres]

I'm replacing my old double oven (rated around 6.5kW, I think) with two separate ovens, a single rated at 3.5kW and a microwave combi rated at 3.45kW. I'm using the existing cooker circuit in 6mm cable, protected in the consumer unit by a 30A MCB.

Trouble is, both instruction books claim their ovens need to be protected by 16A fuses. I was intending to take them both off the same cooker point (actually daisy-chaining from one to the other). Is there any practical way of separately protecting each appliance, or will the combined 30A suffice?

Any thoughts gratefully received, especially if they avoid the suggestion of running separate cables back to the consumer unit (which is not currently practical).

Using the handy "search" facility would have brought your answer up in no time!

Here's a recent thread asking exactly the same thing as you: //www.diynot.com/forums/viewtopic.php?t=144227

Many thanks for the speedy response. The thread you referred me to proved very useful. And it linked to another where I discovered the "daisy-chain" is not recommended: I need to run the two ovens in parallel off an additional two-way consumer unit.

Clearly there's a trend away from double ovens and towards separate units. Thanks again for your help.

There's also a trend towards the buying of ovens which are designed with the expectation that houses will be full of 16A circuits.
