Hi
I am in the process of redoing my kitchen and getting a separate hob and double oven, for cable sizing would you use the example calc below for each item, which was a response to a question last November:
"The rule of thumb for cooker circuits is:
32A MCB or 30A fuse
6mm flat Twin+Earth cable
Applying diversity:
9400w
9400/230 = 41Amps maximum
Formula: 10A + 30% of rest + 5A for any socket outlet
10 + 0.3 * 31 + 5 = 24.3A
We only need to cater for 24.3Amps or only 19.3Amps if no socket outlet.
If its a short run from the cooker to the consumer unit then you could get away with 4mm cable.
I would use 6mm cable just incase you get a bigger cooker in the future or the cable run is long"
Thanks
Nick
