The scenario
A data center must maintain critical cooling and UPS loads through utility interruptions using N+1 generator redundancy and two paralleled automatic transfer switches feeding separate critical bus sections.
What is in this drawing
Read the decisions behind it.
01
Utility and generator parallel buses feed both ATSs for selectable redundancy
02
Normally-open tie breaker between critical bus sections allows reconfiguration
03
Each critical bus supplies dedicated CRAC and UPS loads through individual breakers
Use when designing or documenting standby power distribution for data centers with multiple generators and automatic transfer switches.
