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 am in agreement and the doc does not reference smaller jobs. 


    Even your example is 3 kW in comparision to their 2 kW. 


    I have most commonly worked on sub 100 and for that scale would not go less than 5 kW usually. 


    As an example a colleague of mine is being pressured to revise his load calc for 47 flats from 5 to 4.5 kW to fit inside an available 222 capacity. Even doing that would be about 211 without landlord power. I am not comfortable about that personally as these are a mix of 1 and 2 beds (panel heaters) 


    Thing is if a client comes across those figures it becomes a pain to explain to them.
