Just wondering if someone can help me. Does the main incoming supply fuse need upgrading from 60A, if on a consumer unit theres 3 30A ring mains, 2 6A lights, 15A Immerson + 40A Cooker? Does it need to be 80A?
afaict normal practice is not to bother about the service fuse unless it actually blows and usually when it blows the supplier tends to change it to 100A anyway (suitability of the supply cable permitting).
as long as the cooker and the immersion are the only heavy loads with long run times (washing machines, dishwashers and tumble driers don't generally run long enough to be a problem, service fuses don't exactly blow fast at moderate overload) you should be fine.
