Hi guys,
Ive won an electrical contract at a 4 story pub and need some advise on size of supply i need and size of cable to each restaurant. The building floors -- ground restaurant/pub ,first thai restaurant / secound office / third 2 bedroom flat.
Ive been asked to supply the two restaurants with a 90kva supply by the architect which i thinks way too much.
The current supply to the building is a 100amp per phase 3 phase supply. Flat on L1 office on L2 and both pulling little power around 25 amps each at max demand. Each restaurant put a 35mm 4 core into them? And will the current supply be able to hand the two new 3phase loads.
I have applied no diversity or discrimination yo the 90kva because i dont kno how to correctly...
Would really appreciate someones input im hoping i can keep the current supply without getting UKPN to upgrade to 200amp per phase and using ct chambers to meter the new supply!
