Has there been a consensus as to how to comply with both 700.3(F) for fire pumps without violating 695?
Following NFPA 70-2020, we have a case where an emergency generator supplies emergency power to a fire pump and egress lighting, via two separate circuits.
(There is a third circuit but it is 701 - standby loads).
It is a highrise building. The fire pump is classified as legally required emergency power.
Temporary generator docking station needs to cut into circuit between the permanent generator and fire pump controller.
How do we wire these two circuits to docking station and still comply with 695 for the fire pump circuit?

Not sure what part of 695 would be violated?

695.3 Power Source(s) for Electric Motor-Driven Fire Pumps.
(F) Transfer of Power. Transfer of power to the fire pump controller between the individual source and one alternate source shall take place within the pump room.
Entire 695 appears to be written for one alternate source. I have not been able to determine if there is a section where it describes how to handle 2nd alternate source.
A second (manual) transfer switch is needed between permanent Standby generator and a backup standby generator.

Docking station would it interrupt the emergency generator temporary or not?
