Fire pump generator conductor connected without overcurrent protection

[hhsting]

See attached sketch. I. have onsite generator which feeds fire pump. However the conductor from generator to enclosed circuit breaker 200A have no overcurrent protection and they run several hundred feet. When they enter the building a 200A enclosed circuit breaker is provided.

Should not the conductors require overcurrent protection?

Is the entire run outside until it hits the 200 amp breaker?

Yes the generator is outside and cables are run outside underground until they come up into the building electrical room right into the 200A enclosed circuit breaker.

IMO the install would comply with 240.21(B)(5)

Sounds like the unlimited length outdoor tap rule applies.

How is the conductor a feeder?

Because it is broken up into two circuits, each with their only OCPD at the load end.
Also, I am not sure that you can have that 200 amp OCPD on the line side of the transfer switch.
