Hello!
I have just bought a 7.2kW induction hob to replace an old ceramic hot-plate 5.5kW hob (which is a pile of crap, 5 mins to heat up, 20mins to cool down, i have no idea why anyone would want one).
On the same ring is a 2.4kW oven.
The CU has a 32A breaker in it. There is cabling in the wall between the CU and the cooker switch and then there's t+e to the oven and hob - I don't have the exact details of what size any of this is.
Now from what I have read here a 7.2kW unit by itself is fine with a 32A fuse, and 6mm^2 cable, but as I have an additional oven there too, how much beefier do I need things to be?
Plan B would be to take the oven off the cooker ring and put it on with the sockets as it only needs a 16A fuse and 1.5mm^2 t+e (as quoted from the installation manual) - this would be similar to in my old house when I had the kitchen done that the fitters put the oven on the sockets ring.
I haven't taken into account diversity yet, but wanted to guage opinion before I go any further - I'm not averse to calling a spark out but I know I'm competent doing the work (I worked with an electrician a few years back), so would rather learn about it too.
Many thanks for your time
Alex
(just to add, distance from CU to cooker switch is around 2.5m, and less than 2m then to cooker - the cable length that is)
