Retz, 1to1.5mw kaya ibigay ni meralco transformer for free (no step down needed) as long as susunod ka sa guidelines ng location ng transformer. Unless otherwise you will be constructing a high rise building with a load more thwn 2mw.again depende sa division of load mo pwedeng hindo ka na kumuha ng another stepdown transformer.Similarly, irelevant na kung ano gusto mo mangyari - depende sa design mo kung primary-secondary or sub or lahat direct metering (another design rule will be applied by meralco).
Imho kung commercial complex at required ka mag genset with 100% back up mag primary-sub meter ka mas matipid sa wiring ay simlple design ng transfer switches mo. Cons kukuha ka ng tao taga reading at taga bill at taga singil.
