I am doing a full renovation on a 4 bed house and once the electrician had got hold of all of the kitchen specs, he reckons we need to upgrade from a single phase to a 3-phase supply. He reckons max demand will be 150-160A.
I was under the impression that it is quite rare for domestic properties to be on 3 phase and if I could avoid the the additional cost and time (6-8 weeks waiting list for install) I'd prefer to!
I have 4 floors, basement, ground, first and loft conversion. Heating is underfloor with mains pressure hot water cylinder, so all powered by gas.
The main issue are the ovens and induction hob in the kitchen, but I would have thought with diversity the load would drop accordingly?
Would anyone be able to provide a sanity check for me? I think it is a close call! Below is my list of the main connected loads taken from the appliances:
Cooker Ring
60cm Pyroclean Right Hinged Oven 3.7KW (16A)
60cm Pyroclean Left Hinged Oven 3.7KW (16A)
Combination Microwave / Oven 3.1KW (16A)
