“Draw a feeder distribution single line diagram for a retail center with a 12.47 kV utility service, 2000 kVA transformer, 3000 A main bus, metered grocery and restaurant tenant feeders, central HVAC, and parking signage loads.”
그 이면의 의사결정을 읽어 보세요.
A 2000 kVA transformer feeds the 480Y/277 V retail bus.
Grocery and restaurant feeders have individual demand meters.
A central 600 A feeder supplies rooftop HVAC equipment.
Parking and signage are isolated on their own feeder.
Use this for a small retail center with common-area services and tenant billing. Utility meter location and tenant-service requirements vary by jurisdiction.

The required metering arrangement depends on the utility, lease structure, and local code.
Why is HVAC separate from tenant loads?
Central plant equipment is commonly a shared landlord service rather than a tenant branch.
