Optional Modes of Parallel Operation:
Maintenance Bypass and Redundant CBP
There are two optional modes of operation in this Parallel Capacity/Redundant
system:
•
In
Maintenance Bypass
mode (optional), the SMB bypass supplies the load and
isolates the SSBM and UPMs for maintenance purposes.
•
In
Redundant CBP
mode (optional), if the CBP breaker fails to close during a
manual or automatic operation, the SSBM automatically closes the MBP
breaker to maintain power to the critical load.
The following descriptions provide the Parallel Capacity/Redundant system
optional operating mode differences.
