I am re wiring the consumer unit in my daughters house, replacing fuses with a split load consumer unit. Replacing 5 amp lighting circuit with 6 amp mcb, and 32 amp rings with 32 amp mcbs is not a problem.
However, the cooker circuit is currently rated at 45 amps, which seems a hell of a lot of power for a 4 plate cooker with grill and oven. I know that unlike most other circuits cookers can be (easily) 90% loaded for Xmas dinner for example, but my question is "as there are no 45 amp mcbs, would it be better to fit a 32 amp mcb, risking the odd trip out under full load, or fit a 50 amp mcb". The cable from consumer unit to cooker is about 4 metres long and is 6mm x sectional area. What the max safe load for 6 mm - I thought about 8 kw?
