What is load density for a hospital?
Hospitals typically design around 4–6 VA per sq ft, higher than offices (~3) due to HVAC, imaging and 24×7 loads.
What is diversity factor?
Not all loads run at once; the diversity factor (often 60–80%) reduces connected load to a realistic maximum demand.
How do I size the transformer?
Size for maximum demand at ~80% loading, then pick the next standard rating; add DG backup for essential loads.
