Hi friends, Iam from india(230v).Iam no good in Electrical distribution.We have a back up generator in our community of 160kva.We have 90 apartments. From the generator wiring is directly done to few lights points and fan points in the household which would make them function when the normal powersupply fails.But I wanted the supply to be given directly parallel to the normal supply with a current limiter so that we can choose the load as per requirement. But the builder says it may not be possible now and he quotes reasons which i dont follow fully and agree...He says there would be problem with gene neutral and normal supply neutral which I cannot agree.I feel all that is required is a automatic changeover switch with a current limiter. note :Generator is a 3 phase generator. But only single phase is given to individual apartment.(may be distributed) My questions are, 1.Is my understanding right that it should be easily possible to connect the generator o/p to each apartments main parallelly with a changeover switch and current limiter. 2.What should be the current limiter rating for above specs. 3.Would you refer to any particular type auto change over switch.Any brand or make or part no.Because builder is washing off hands that he does not know any. Please help me with your suggestion.
