Seen a couple of threads on diversity and excessive max loads recently. Just had a design from a clients for their house. Applied diversity is 196A. Having 2 9kW showers install, A 4kW instant water heater, a cinema room, ring main per floor, lighting circuit per floor and ring main for kitchen. 100A Single Phase Supply No chance of another supply. Hes already having 2 combi showers as well as the 2 electric so doesnt want to get rid of them.
