Yes, this transformer is large enough for the house in
question.A normal house requires 100w/sq.meter area
including Air conditioning.The 930 Sq.meters reqire:9300w.
and add 10kw power reqired for the SPA. So total power
reqired is 19.3KW.A 25kva Transformer can supply power of
20kw at naormal power factor of 0.8. So the transformer is
is large enogh to meet the power requirement of the house
in consideration.
