I currently have a double oven fed from a 45A MK cooker control unit with integrated 13 amp socket. The CCU is fed by a 10mm2 cable and protected by an RCD and 32A MCB about 8m from the CCU.
I’m planning my new kitchen and have chosen the appliances.
I’m trying to plan the best way to connect these up. Running additional cables neatly from the CU to the kitchen is not easy so I'd really like to avoid that. I suspect with diversity, it is reasonable to assume that the existing 10mm2 feed will be adequate to supply both ovens and the hob though I probably need to up the 32 MCB to 40A?
Then the problem is connecting them up. I want to keep the CCU to allow me to isolate all the appliances easily from above the worktop.
I was thinking the neatest and safest solution would be to use a small 3 way (+ isolator) consumer unit in a cupboard close to the ovens & hob. Take the switched load output from the CCU in 10mm2 cable into the 3 way CU and from there feed the appliances:
Can anyone see anything wrong with that proposal or have any better suggestions?
I’m planning my new kitchen and have chosen the appliances.
- The gas hob will change to an induction hob that can pull up to 30A (7.2kW)
- The double oven will be replaced by:
- a single main oven (16A)
- built-in combination oven/microwave (fitted with a 13A plug)
