Hi. I know similar questions have been asked but I seem to see some conflicting answers. The original set up was a 9kw all in one oven and hob, running on 6mm cable to a 30amp fuse. I want to fit a 6kw hob and a 5.7kw oven. They are on opposite sides on the room so can I add a terminal box in the loft and run another 6mm tail to the new oven (about 7m of extra cable) with a fused switch in the oven cupboard, and leave the hob to run from the original wiring. Fuse board is full so can't run another cable into it as it is. Many thanks for any help you can offer
6mm t/e on a 30 amp fuse or mcb is a standard cooker circuit and allowing for diversity is good for up to 15kW. What you're proposing sounds ok although you won't need a fused switch for the oven, just a 45 amp isolating switch.
