hi all
just wanted to get some opinions. got a place being converted in to two flats and everything will be electric! new edf supplie(s) to go in and so need to know what max demand in kva is for edf to evaluate.
just one flat
electric shower 10kw
electric oven/hob 8kw
electric water htr 3kw
storage heaters for main heating 3x 2.5kw & 1x 3.4kw
and then the usual couple of rings and lighting circuits.
using the onsite guide for diversity values I come out at 176A
even with a g factor of 0.8 (playing it safe) it's still 140A. customer is thinking there wont be a economy 7 supply so it'll all be on one supply.
not had much experience where everything is electric so looking for some views from people that have and what the scenario has been to get over the large load. 3phase seems a bit ott?? is there a larger supply available than 100A single phase although then i guess DB's etc aren't rated high enough. i realise that in real life it shouldn't pull near to 140a but thats what it is coming out at on paper and if it went wrong with me saying less than 140A i'd cop the blame which i don't want.
thanks for any help
