Submeters/Power Monitors

See switchgear#SPD's/TVSS's

Panelboards

DISTRIBUTION/DIST PANELS & UNIT LOAD CENTERS/...

Enclosed Circuit Breakers

Treat as disconnect switch.

Generators

Add DISTRIBUTION FITTINGS/GENERATOR SET UP.

Generator Connection Cabinets

Use a Distribution Panel of equal amps. Or a transfer switch.

Transfer Switches

Transfer Switches 1200A+

Use 1200A and add an additional TRANSFER SWITCH item to make up the remaining amps.

Meter Centers

SWITCHGEAR & METER CENTERS/METER CENTERS/... METERING SECTION

Adjust Factor 1 for meter stacks, delete zeroed items.

3. Review

1. Generator

• Ensure takeoff is in the generator Area and System breakdowns
• Put location, quantity, and type on OneNote
