Xfrmr Replacement

[Alwayslearningelec]

Have a nice transformer replacement job I’m pricing. As far as I can tell so far it’s pretty straightforward.
Only real concern, I’d have(especially since it’s a hospital) is losing power to loads being fed from secondary side xfrmr panel. That may be an issue if the loads would have to remain active correct? Temp?

Does the "CR" denote Critical Branch?

It may why ?

Well, Critical is for patient life support which will mean all parties and staff will be on standby to manually ventilate and cover what ever other surgeries, trauma/triage rooms, etc... may be affected if normal power was lost during the job. It would probably mean it will be done on a planned shutdown with a window of time allotted. When I was involved in these type projects it was usually from 11:00 PM to 7:00 AM. The state agency governing hospitals were made aware of what was going to take place and we had to submit a detail schedule of events with times of start and completion. It can be pretty involved.
