IDNO Loads

HI All

Just come across the attached - a snippet from an IDNO's documentation about loads for residentials.

Loads a lot lower than I am used to - what are peoples thoughts on this?

I would not be comfortable going down that low - e.g. an all electric flat with panel rads and a 3kW cylinder - don't see how you could drop down so much.

i tend to see 4.5 to 5.5 kVA for all electric flats, lowerend being for single bed units and 5.5 for two bed

I can't see how diversity applies for electric heating.

Actually you do not need as much diveristy on a cold winter day, if the transformer is also outside and cold, it will be able to take 100% overload - it too is rated based on temperature rise, depending where these figures are for, there may be this sort of assumption n hidden.

Of course it goes horribly wring for indoor substations, and ones that are supposed to be fan cooled but the air intake fills with snow.
